Mana & Cambridge CD4 v Naim CD3.5 - a 2nd opinion

Posted by: Steve G on 04 December 2001

I took a trip over to Mr. Pig’s house last night to have a listen to his system and in particular to consider his allegation that a £99 Cambridge Audio CD4 when treated to Phase 4 Mana comprehensively outperforms a Naim CD3.5 on Mana Phase 3.

As set up initially Mr. Pig’s system was:

Linn LP12 on Phase 5 Mana.
Phase 3 Mana with a 72 on the top shelf, CD3.5 on the shelf below, a 250 on the next one down and a Hi-cap and turntable power supply sharing space on the bottom shelf. Speakers were Linn Saras, stand mounted and placed very close to the wall firing straight out. Wall was about 16’ or 18’ foot square and the speakers were perhaps 10’ apart with the listening position around 12’ away. The Mana racks were against one of the side walls perhaps 3’ from the left speaker. The room is quite bright sounding.

Initial listening was done with the LP12 and initial impressions were pretty good. Nice punchy midrange, reasonable bass extension for a standmounter but I was a little concerned about the treble quality which seemed a little ragged to me, with a noticeable effect on vocal sibilance. Listening to the CD3.5 was similar but listening to some of my music here (notably Massive Attack) identified a potential issue with the left speaker receiving considerably more boundary extension that the right speaker. The speakers were equidistant from the room corners but while there was a hollow alcove behind the right speaker the wall behind the left speaker was solid. This coupled with the nearby position of the racks plus a small table and plant-pot in the same corner could have been the cause. I think this could probably be cured by experimenting with speaker position as moving the Sara’s out slightly from the wall improved things a little.

Anyway onto the main event and the LP12 was moved off the Phase 5 Mana and replaced by the Cambridge Audio CD4. A number of tracks were used for testing including The Ghost of Tom Joad by Springsteen for fast transients, Sullivan Street by the Counting Crows for challenging vocals and Diesel Power by The Prodigy for bass etc. Initial listening was done on the Naim deck and then the track was replayed on the CD4. The Naim deck coped reasonably well with most of the tracks but the sound was poor with the Prodigy track. To my ears however the CD4 was very poor on all of them and unlistenable on a couple of tracks (Eminem’s Stan for example).

It’s a very bright and aggressive sounding player sounding to me like a graphic equalizer had been fitted and all the mid-range levels pushed way up. Lots of immediate impact because that area of sound that the Sara’s do well (mid-range) is emphasized but bass control and extension was poor and treble plain awful. Mr. Pig was concerned that the player in fact sounded a lot worse on Phase 5 Mana that when previously tested on Phase 4. The top tier was therefore removed and certainly the CD4 sounded a lot better now, although to my ears still some way behind the Naim player in overall presentation. Mr. Pig didn’t agree but I think we’re looking for something different from our systems – I like a balanced controlled sound capable of dealing with everything from Sibelius to the Smashing Pumkins and from Emminen to Mozart. Mr. Pig would appear to prefer a fast punchy sound with its inevitable focus on mid-range performance and certainly in that area the Cambridge deck performed well, notably with cymbals.

For someone who listens mainly to vinyl with only occasional use of the CD player I can see the point about the Naim player not being worth the extra £1000 or so it cost. For myself who mainly uses CD with occasional use of vinyl it’s a no brainer – I couldn’t live with the harsh sound of the Cambridge player.

My supposition was that as Mr. Pig’s system was setup primarily for the LP12 neither the CD4 or the Naim (both aggressive decks) suited it and perhaps a sweeter, less aggressive player would be better. Amongst a few bits and pieces I’d brought along was my old Micromega Leader II, which I normally deploy as a transport for a Meridian 203 DAC. This took the place of the Cambridge player atop the Phase 4 Mana and to all ears (myself and Mr. & Mrs. Pig) comfortably gave the most musical performance of any CD player tried. Interestingly this improvement collapsed when the Meridian DAC was hooked in. The DAC was also tried with the Cambridge player and certainly to my ears benefited significantly from it.

Significantly in my main system at home (32.5/SNAPS/140/Credos on a Target TT5 rack with sources on a Wallnutt 2 tier wall-shelf) in which I use a CD3.5 as my primary source the situation is reversed. The Micromega player gives the Naim a good run for it’s money but my system benefits from the extra attack the Naim player brings.

Overall I’d say Mr. Pig’s system outperforms mine perhaps primarily due to being housed in a much bigger room (my listening room is 12’ x 8’ and also houses my main computer and lots of storage). The Sara’s didn’t really do it for me as their obvious colouration, while dramatic in many ways, didn’t work with much of the music I listen to. Controversially I’d have said replacing the Sara’s with my Credos would have improved the balance of the system a lot but even with those in place I suspect a smoother CD player would give the best results.

Thanks to Mr. Pig for his hospitality and his wife for an endless supply of tea. And folks, Mr. Pig is much nicer in person that some have imagined from his forum persona…

He's a nice guy, and will be missed on this forum (despite occasional over-zealous rants wink )

Steve, you should pop round to mine or me to yours seeing as you're nearby. My system is undergoing massive flux at the moment (having temporarily removed a fair amount of Mana from under the sources/amps in favour of the speakers, and also undergoing major work with the TT and interconnects (getting VTA right, sorting out RFI, etc.) but it's coming along nicely. My new preamp arrives today (after 3 months wait!!!!!!) and I'll hopefully get the dealer to reset my TT (it was new and hence needed a revisit to sort out a couple of things like VTA and so on).

My own take on the Saras is well known - I'm not a big fan - but I have heard the comparison between an Arcam 7 series CD player and the 3.5, and whilst it wasn't as conclusive as Mr Pig claimed for the CD4, the Mana certainly does change things and move goalposts. Whether that's a good or a bad thing is, of course, up to the ear of the beholder...

Good posting Steve. It seems to me that based on your report Naim low end CD players (CD3.5, CD3, perharps CD5) now face stiff challenge from some worthy competitors. I have the same experience with my CD3 and Mike Hanson Cambridge CD6 (I think). Yes, the Naim CD are better but in term of performance versus price, the cambridge CDs are way ahead on the game. I guess it applies to other players such as Rega, Exposure etc. Also, 2 conclusions can be drawn from your reports:

1. people have diffeent preference when listen to music. There is no "right" sound.
2. Naim players are good but cost way more than others and for people who dont use CD are main source, they may consider other design for near Naim performance but much less cost. This seems to be the cast with amplification as well as I reflect to Alex S with his experience (and seconded by many) on amplification.

There seems to ba a consensus that Mana has an 'effect' rather than just being a neutral support system like Base. You either love it or loath it. So, as with all things sonic, go and listen to it. Forget the politics, just decide whether you like what it does.

Steve, Did you try the Cambridge on no Mana? If so, what did it sound like then?

Tuan, My own opinion is that Dynavector amps outperform Naim at the 2K and 4K price points; ie. an HX75 is better than a 250 and an HX1.2 is better than a pair of 135s. Others will disagree (although the main disagreement will come from those who have not listened to the DV amps).

I suspect that Naim may soon catch up again by using its 500/150 technology in restyled 250 and 135 replacements. Just a hunch, but if I was at Naim that is what I'd be doing. Along with making me a super Hi-Cap of course.

Personally, I don't think Naim have serious CDP competion except at the CDX level. (There are plenty of 1K players but they don't deliver the 'Naim' sound). The cost of a CDX/XPS at 4.5K must make it worth looking at alternatives. The CDS2 which I am proud to own is a magnificent player and I'm not even tempted to listen to the competition. It is particularly fine when you buy it mint ex-dem with a mint CDPS!

Second Hand, Naim are unrivalled for quality, value and a lack of depreciation coupled to an ease of selling. We should thank their servicing policy and customer support for that (in addition to that fetching green logo).

Naim have very serious competition with regard to their loudspeakers at all price points but that is hardly surprising.

I think that if there were 10 Mana tables under the cambridge, it could sound better.

Many months ago I told you that singers in Israel found the magic of the Mana tables, and there are ranks, A poor singer that sings while he is standing on two phaze 4 - his voice sounds like he is Frank Sinatra.
The same with a whoman singer - if she is black
her voice goes like she is Shierly bassy, if she is white her voice goes like she is Jennis Joplin.

One singer who tried to be too wise, stood on several phases and was wounded hard when he fell.

I have always had a real difficulty with CD players, all the ones I could afford always sounded like, well, CD players. I have run a decent vinyl front end for ages, and have found that obtaining that level of performance was out of my price range.

As far as I am aware, and obviously bare in mind that I have not heard everything out there, CD players start to genuinely work for me with no reservations with the CDX. The CDX is the cheapest player I have personally heard that gets the music in time and in key in the way that a half decent record player does. The drums now sound lined up in time - i.e. the hi-hat is in time with the bass drum etc. The musical phrasing makes sense. This is obviously a good thing in my book. Even so the CDX seems to be a bit of a contentious issue here, with quite a few not seeming especially enamoured with it at all, though I can honestly say mine exhibits none of the aspects (harsh, edgy, forward) that they seem to criticise. I really like mine. I can enjoy music and forget I am listening to a CD player, I can think of no higher recommendation. It is bloody expensive though, 2400 quid for the entry level of music playing CD players…

The point I am attempting to make is that at the price of the CD3.5 I honestly don't really like CD, and would personally choose say a Rega P25 with a decent MC cartridge and not even bother with digital. I suspect this is the possibly the conclusion that Pig has come to as well, though perhaps has not quite realised it yet. It is becoming increasingly obvious that everyone hears differently and has different priorities, but for me neither the Cambridge nor the CD3.5 will adequately do what I personally want, no amount of Mana will change that (IMHO it will actually make matters worse). So there you go.

Tony.

I'd like that - I'm interested to hear how different systems sound in comparison to mine and to any improvements others could suggest for mine.

The Mana makes a difference without a shadow of a doubt and it certainly appears to be a useful tuning tool. Whether it improves things or not would appear to be dependent on your ear and perhaps more so the configuration of your system. Changing my system from 92R/90.3 to 32.5/SNAPS/140 removed some harshness issues I had with the effect of a Naim player on my system balance and I'd be concerned that the "Mana effect" might bias the system further towards brightness and aggression that I'd like. No way to tell of course without trying it - something that doesn't appear too easy with Mana kit.

Possibly, although it should be noted that the player I liked best in Mr. Pigs system (a Micromega Leader II that I bought used for £200 a few years back) was probably nearly as expensive as a CD3.5 when new. I'd like to have heard one of the Audio Note CD players with a valve output stage in Mr. Pig's system as I think that would have sounded nice.

quote:

Yes, the Naim CD are better but in term of performance versus price, the cambridge CDs are way ahead on the game.

I've only heard the Cambridge CD4 in a Richer Sounds demo and in Mr. Pigs system but it's an impressive player for £99, no question. I listen to CD a lot though and I couldn't live with it long term.

Absolutely. The important thing is to get a sound you're happy with.

I don't agree (although I haven't heard enough to come to a firm conclusion) - the CD4 sounded horrible on Mana Phase 5 and ok on Phase 4. I suspect it would have sounded better balanced off the rack altogether but I think that is the fault of the player not the Mana racks.

On the other hand Mr. Pig thinks there may have been a setup problem with the Phase 5 shelf and he may be right (he's not convinced his turntable sounds right on it either).

Wow, let's not go there...

I've heard a couple of components which lurk in that particular category, and I was oddly underwhelmed.

The only ones that I've heard and really rate are the Sennheiser HD600 headphones and the Audio Physic Virgo loudspeakers...

Steve G,

Although I'd never heard it, I don't believe to the Mana stories as they are told to us here.
Every component has its upper limits.
It is totally unbelievable to me (unless someone does it with a mean purpose) that you can take a cheap component and outperform with it
An expensive one by doing some ‘tricks’.
And it is obvious (to me) that you can perform the same ‘tricks’ to the expensive component, an act that has to bring the same improvements you recieved with the cheap one, unless you are talking about miracles and other things I don’t believe in their existence.

The argument is not that a better component is beaten by a lesser one, it's that the latent differences in components is less than we'd think, and the addition of a 'super support' can tip the balance either way.

A 'lesser component' may only be lesser within the constraining limitation of its own physical construction - the circuit topology, for instance, may be much closer in electronic terms than the 'non-super-support'ed component can demonstrate. Add the 'super support' (e.g. Mana) and you remove one of the factors which was increasing the gap between the two players - i.e. its physical isolation/vibrational 'earthing' - and you find that perhaps you are hearing the component properly for the first time...

It's an interesting point, and one I've heard myself, so I do believe in it. It's not unique to Mana, but it is most immediately obvious with their supports.

Bearing in mind that in real terms there is only an objective 10% difference in the performance between (say) a Cambridge Audio CD player and a CDS-II (my figures; they are not the important bit), but in audiophile, musical and/or perceptive terms that last 10% may be the 90% most musically significant, if the addition of Mana to a player gains it an increase in effective performance of 12%, it may overtake a far more expensive player by some margin in musical terms.

This is of course an illustration and I haven't tried such a wildly varied comparison, but with more similarly constructed, single box players you may find that the technical differences in the circuit topologies aren't that significant relative to the extra improvement that a 'super stand' can offer....

a can of worms that I would rather avoid.
I'm with you there but the presence or absence of an 'effect' is interesting and I think one of the reasons that Mana provokes such debate.

In my limited experience I would venture to say that Mana is performance 'enhancing' most of the time. Occasionally, for whatever reason - I suspect it to be something to do with the leaf spring suspension of my CDS2 - I have found it performance 'debilitating'.

Tony L has a general dislike of Mana, fine, I mainly disagree with his findings with regard to 'tune loss' but 'tune loss' is exactly what happened to my CDS2 on three levels (not prescribed phases exactly) of Mana.

Many have found that Mana works particularly well with cheaper CDPs DVDPs and the like and less well with more expensive equipment. I am not surprised since it is isolation and suspension which is integrally much better with more expensive players. The clocks and stuff are often the same or not much different. Conversely, and against my expectations, I have heard a CDX on a pile of Mana and thought it much improved.

Base is not capable of making silk purses out of Pig's ears. It allows the inherent strengths of good equipment to come to the fore - hence you see it under almost anything expensive at hi-fi shows. It is neutral in that sense, not a 'performance enhancer' nor a 'performance debilitator', just a 'performance facilitator'.

I think it's an interesting comparison to make even if, as in this case, I much preferred the Naim player.

I don't think so - I think the issue almost certainly relates to the speakers.

Strange!


Not having detailed experience of Mana I wouldn't know, however it certainly did sound better once the top stage had been removed. Mr. Pig also commented he had been experiencing some problems with his turntable since the last stage had been added, this he attributed to a setup problem.

I can see that!


In my case I heard it. Whether the harshness problem was done to the Cambridge player or to it's role within the context of this particular system I couldn't commit to. However the CD3.5 also sounded harsher in that system than it did on mine so that may give some indication.

quote:

No, however I did comment to Mr. Pig that I thought it would sound better on the floor than on the Mana racks as I felt they were emphasising a harshness in its sound.

Interesting observation!


This was related purely to the improvement in sound noted when the Cambridge player was moved from Phase 5 to 4. I thought the Mana racks were highlighting a problem with the player in the context of this system, which is no criticism of the racks.

I Wonder!


This was from Mr. Pig not from me. I didn't hear the turntable on Phase 4 so couldn't comment.

ok, that explains it!


That was a joke...

quote:

And your next mission should you wish to accept it?


Removing the top tier was Mana enthusiast Mr. Pigs idea, not mine.

Personally I've not heard enough to make a decision on the Mana racks one way or the other. The only way to do this I think would be an extended home demo with my own system - something I'd like to try. One thing is clear - they certainly make a difference to the sound of the system. The only think I haven't decided (and I think this may well be very system dependant) is whether that difference equates to an improvement.

My own experience with racks is limited. Moving my turntable and CD player from my Target rack to a cheap wall shelf gave an immediate and tangible improvement in clarity. In comparison the only expensive rack I've bought to date, a Stands Unique model, was absolute crap and only fit for use in my home cinema system. I did look at one of the Quadraspire models but to my eyes (and more importantly SWMBO) they're way too ugly to consider (someone said they look like a stack of 1970's coffee tables which is spot on).

I quite like the look of a reasonable stack of Mana (say phase 4) myself but I'm not sure SWMBO would agree. I might buy a couple of those bits that fit under the racks (or possibly for under my Credos) to try but until I can get a decent home demo I wouldn't consider more.

I hope this clears up my views on the Mana thing.

As for Naim kit - I bought mine originally because both my wife and I felt (after extended demoing) that it presented the best performance at the price point we were considering. If I'd had the cash I'd have preferred a Krell/Martin Logan combination. The best system I've heard so far was a Theta Digital front end, feeding Audio Note valve amps driving Martin Logan speakers - this I felt blew away anything that I've listened to from Naim.

Also only 1/3 of the hi-fi seperates in use in my house currently are Naim units which I think undermines the role you've decided for me as a Naim apologist! Thanks for the thought though - perhaps I should send Paul Stephenson and invoice and ask for a piece of Naim kit in payment? Hmmm - I wonder what a 500 would sound like in my system. Nah - wouldn't fit on my rack. Has to be a CDS then...

I don’t think you can measure audio equipment systems in a simple mathematical numbers because what counts is the listener’s impression of what he is hearing.
If the impression could go by comparing mathematical numbers like I understand you are suggesting, Maybe Naim, for example, could manufacture a very cheap
Cdp and recommend to set it on a Fraim rack – and maybe they could prove with numbers that the cheap/Fraim have the same quality like an expensive and let’s say QS or the like.
I simply don’t believe it is true, and if you think it is, you are questioning (to my opinion) pulling out the ground under the sophisticated planing and manufacturing by thinking that you can bypass it with some other ways.

Paul D

I agree with you, althogh I think that if Mana does something to a “x” Cdp, it has to do the same to a “y” Cdp. Top Cat suggests that maybe “x” cdp has some faults that “y” cdp doesn’t have.
The Mana support “fixes” exactly these faults and that makes a match between “x” and “y” even if the second is a better one than the first (That’s if I understand TC correctly).

I originally posted this as a footnote to a thread on the Mana forum where Mr Pig is still discussing the superiority of his Cambridge player and to which Vuk kindly posted my intitial entry on this thread.

------------------------------------------------

As a footnote I reorganised my racks last night to take 3 CD players for camparison in my system - the Naim as usual in its place on the bottom tier of my wall shelf, the Micromega (without the addition of the DAC) on shelf 3 of my amplifier rack and an Arcam Alpha 1 on shelf 2. The Naim was linked to the 32.5's tuner input with Chord Solid, the Micromega to tape 2 with Chord Cobra II and and the poor old Arcam with a cheap freebie cable and RCA-BNC convertors to the aux input.

Listening to The Ghost of Tom Joad on the Arcam first and it sounded pretty good. Next the Micromega and a easily discernable improvement in treble quality (very important on this track) was heard. Next the disk was spun on the Naim and the disk again sounded very fine, although I'd have said certainly no better than on the Micromega. Moving to the opening track from Massive Attack's Protection and the Arcam isn't great - bass control especially is poor. The Micromega is a big step up - much tighter bass control. Then onto the Naim and the bass is marginally heavier and better controlled.

Overall I preferred the Naim with the Massive Attack and the Micromega with the Springsteen track. Some of the Naim's better bass control undoubtedly came from it having several advantages - better isolation on the wall shelf, an unbuffered input on the pre-amp and a considerably better interconnect. With these things reversed it's quite possible I'd have preferred the Micromega with both tracks.

The conclusion? My Micromega is a bloody good player - unhindered by the Meridian DAC (and with its digital output switched off) definitely better than the Naim in Colin's (Mr. Pig) system and probably in mine too. This backs up my original demo in which I preffered the Micromega to a Naim CD3. Unfortunately these days its playing up and won't always recognise disks being loaded, which is why I replaced it with the Naim CD3.5 (bought used for £650 at which I think it represents great value). Perhaps I'll try to get it fixed and serviced and relegate the Naim to my bedroom system.

It's probably worth noting that the Micromega when new (it's ancient now) was probably as expensive as the CD3.5 although it's a lot older.

I commented to Colin when I visited that I don't think Naim CD players particularily suit Naim systems (the overall effect being too aggresive) although of course this would only apply to the low end players and amps I've heard to date.

And yes I am going to post this on the Naim forum as well! It should undermine some allegations that have been made over there of me as a Naim apologist.

On the Mana side of things my visit to Colins house has interested me in the Mana equipment and I might invest in a pair of soundstages to try under my speakers in an attempt to address some bass control problems I have with the use of Credos in my small listening room.

Steve
