Hi guys I'm new here need some advice

Posted by: cunningplan on 12 January 2003

Hi to everyone, please be gentle with me I need to have some input and advice. My system consists of Nait 5, Nap 150, Monitor Audio Silver 8's and Roksan Kandy KC1 CD (I know the CD is probably the weakest link but can't afford to change it yet to a Naim) My speaker cable is Chord Odyssey single wired and Interconnect is the Chord Silver Siren with an adapter (this is where the problem lies I think) I've just recently added the Nap 150 and I'm finding the mid range on my system sounding a little nasaly for use of a better word and I'm convinced the interconnect is the cause. I'm tempted to spend a little more on the interconnect as a short term measure to tide me over until I can upgrade to a Naim (undecided yet as to which one)If you nice people can give me some ideas as to what sounds good from your experience it will be appreciated, my budget no more than £200

The problem is not so much the adaptor on the interconnect, but a mismatched loudspeaker cable.

I repeat this again: Naim amplifiers MUST MUST MUST use Naim NAC-A5 loudspeaker cable

Also I doubt you are doing your system any favours by using Monitor Audio loudspeakers.

Hi Andrew
Thanks for your input but I have to disagree my speakers and speaker cable are very good and I like the warm rich musical sound they produce. I did audition various combos and found the above to to have good bass and excellent detail,the problem I've now got as only come about by adding the 150 I can't accept the speaker cable and speakers have become crap by just doing that. I've spoken to the dealer and he seems to think it's the CD and Interconnect, but as I said I want a stop gap upgrade until I can afford a new CD

Do a search on NACA5. Andrew is completely right and it's been said time and time again. The electrical properties of A5 are part of the amplifier design. Using another cable will at best sound different, usually worse and in some extreme cases will cause the power amp to oscillate and eventually fail.

I'm surprised your dealer didn't force some A5 upon you.

Regards

I know the general accepted preference is for A5 with Naim amplifiers, but I too have Monitor Audio speakers (R352s) with a Nait and A5 does NOT work with them, so it's altogether possible Cunningplan has the same situation.
People have to be given credit for making their own judgments on how their sistems sound. Telling every non-A5 user they have it all wrong is really not very helpful.

It's NOT a must, bit imo a recommendation!
If you wanna go safe go for NaC-a5, if you're not blind for other brands, just try some.
In my area there are 3 Naim dealers, and NONE (I repeat) NONE of 'em is using Naca5 with their Naim systems! Roll Eyes
I've tried many different cables, and yes, I agree, most of the times the Naca5 was the best, but there are (better) alternatives.

I'm not familiar with the Chord cable though.

I'm with Andrew, at least try out NACA5 and the basic chord interconnects before deciding to spend money elsewhere.

Thanks Dave
I did listen to various combos including the NAC A5 and even the dealer thought the Odyssey sounded better, as did I. Musically I found it more engaging and found the A5 to me a little cold and clinical. Don't Naim approve of Chord as a good alternative to their own cabling it says so on the Chord website

Din Plugs were once common, but these days are found mainly on Naim Audio equipment. We take great pride in the fact that we produce a range of interconnects to complement Naim and that Chord are the only cable company they recommend.

Why not just get your dealer to lend you a couple of alternative inter-connects on home-trial, most dealers keep several different makes and I'm sure he'd be willing to help. If you find one that works OK with the RCA-adaptor it might be worthwhile having it rewired with a locking Din.

Sadly, Naim don't publish a list of 'approved' speaker cables - they just say you should use A5. I believe it would be enormously helpful for those of us for whom A5 just doesn't work, if they could publish something, but they seem disinclined to do so for reasons unknown.

I'm certainly far from convinced that A5 is the only cable 'safe' for use with Naim amps, although if it had worked for me I'd be using it if only because it's cheap!!

Discussions I've had with Chord do suggest that Rumour and Odyssey may enjoy the 'tacit' approval of Naim HQ, but this has never been formally confirmed.

Inter-connects are less of an 'issue' than speaker cables as I don't believe there are any fundamental compatibility problems that have to be considered. Good Luck!

David,

Subject: Cables Again

Please can I draw your attention to the following notes:

****Ed's Note: MANY CABLES WILL 'WORK' IN PARTICULAR SYSTEMS, BUT IF THE SPECS ARE VERY DIFFERENT FROM NACA5, THEN PROBLEMS MAY OCCUR WITH CERTAIN SPEAKERS****

FOR INFO THE RELEVANT SPECS ARE:

1.3 - 1.5microHenries per metre (Loop)

MAX 20picoFarads per metre

About 25milliOhms per meter (loop)

MIN Length 3 metres

**ED**

and: refering to Litz type high capacitance cables.

*****ED's Note: DO NOT USE THESE TYPES OF CABLES WITH NAIM POWER AMPS IF YOU WISH TO HAVE NAIM'S WARRANTY - PLEASE SEE YOUR OWNERS MANUAL*****


It should be possible to get cable specs from the manufacturer, and check they are close to this. Obviously the Max 20pF/m is the critical measure for safety, although I understand the inductance is also important to get the best sound.

cheers, Martin

Thanks guys I think I'm going to try the approach of borrowing different interconnects and see what comes from that, perhaps I may be taking an incorrect approach here because overall the sound is good apart from this niggle in the mid range I'm just surprised that the NAP 150 should have done this to the system, well you live and learn.

This entry has been edited in response to comments from David an Cunningplan below.

That sounds like a dumb plan.

New: You say you're not unhappy with your current system; you have simply a niggling complaint.

old: Your current system violates your amp's manufacturer's explicit recommendations. You think it's best to continue violating that reco because of your experience in a dem, which appears to have been at a store. What in heaven's name are you thinking????

old: To me it is exceedingly obvious that the best first step is either to dump the 150 or to get a home dem of NACA5. Try it for a week. See what you think. If A5 doesn't solve, or at least significantly ameliorate, the problem, THEN look elsewhere.

new: You say you don't want to throw the 150 out. You don't have to - you can take it back or sell it used.

old: You might also look for some used A4.

old: I hate to be churlish here, but you ask for advice and then reject the manufacturer's own recommendation, one which has satisfied - even delighted - many customers.

old: Asking for advice and then engaging in a dialog in which your repeatedly reject it is a sure-fire way to alienate potential advisors, particluarly when you decide to do something that at best complicates your setup.

new: It doesn't make sense to choose Naim's simplicity and then f**k it all up with multiple levels of non-standard cables.

Perhaps you want members of the forum to recommend that you try out different interconnects. If that's what you want, say so. Maybe someone will oblige. If you want to attack the problem bass-ackwards, go for it. Share your experience, after you've done it - especially if it works....

But the approach that is most likely to solve your problem is to try out A5 at home, for several days before doing anything else. I'm not saying your method won't work. It is possible to find 2 sets of cables with complementary problems that cancel each other out. But why go through the hassle, when it is so much more straightforward to give the manufactirer's recommendation a thorough trial before going into what is really a very difficult search?

I realize I have been confrontational here; and, yes, I can see that what I've written may be insulting.

Obviously, I think you're playing games, and that gets my dander up. I am open to posts, especially first posts, with elementary questions, misguided questions, misguided opinions, different opinions - but I do not welcome this sort of game. If I'm misjudging, I apologize.

I benefit greatly from posts which bring alternative views to light, and I really mean it when I write that you should let us know if your interconnect swapping solves your problem. But I'm at a loss to understand the benefit of trying umpteen-squared combos of interconnect and speaker cable when trying out ONE speaker cable might solve your problem.

I'm signing off this thread now. I'll monitor it, but I do not plan to respond to any more comments here.

Regards.

Phil

Martin,
The cable specs are of some help, but not all the cable makers publish these parameters and without knowing what tolerances are acceptable from the nominal figues quoted by Naim, it is very difficult for the lay person to identify which cable is 'safe' to use. Believe me I've been there!

Hence my suggestion that Naim could provide a list of cables which are 'safe' for use with their amps whilst continuing to promote NACA5 as the one they recommend. I believe that would be a very useful service to their user-base and would avoid the need for threads like this!

Mr Barry
Your contribution is about as helpful as a very unhelpful thing and unnecessarily rude to a new forum member. A little more circumspection might be appropriate!

David

I didn't say I was unhappy with the system I think it's very good I'm just complaining about a minor niggle which perhaps I shouldn't I'm only trying to fine tune. As far as dumping the 150 well I just can't afford to throw away nearly £800 and it's part of an upgrade path. I still think the the front end is the weak link yet no feedback on that from anyone. This is my first posting here all I wanted was some advice and a couple of the posts have been somewhat insulting. Hi-Fi sound is subjective, what suits one persons tastes may not suit another. I don't insult my friends or other peoples Hi-Fi I've listened to over the years it's their tastes decision and money at the end of the day.

We were under the impression that you did not currently wish any advice on buying a better CD Player - "I know the CD is probably the weakest link but can't afford to change it yet to a Naim"

My own advice to you (other than changing to NAC-A5) would have been to save for a Naim CD5 or Linn Genki rather than a NAP150. Even batter, go for a CDX2 - whatever you do, start prioritising your source.

I have MA studio 20's with Naim stuff for 9 years. Started with a Nait , and now 82,hi,CDX, 250, all with naca 5 cable ( 12 foot lengths). Works fine and is the only way to go. Upgrade your source and go from there. Ted

By the way, the speakers still sound amazing, very clear, great soundstage and very good prat. Ted

Allow me to add to the confusion here... I have an old set of NACA-4 speaker cables from when I first bought my Naim set-up. I replaced it years later with a "newer" version cable that was recommended by the dealer that I bought my system from. To be totally honest, I don't know if this is NACA-5 or not!? It looks just like my original cable, but I can't find any markings on it... at least the old NACA-4 has it printed on the cable. Does NACA-5 have anything on it that will allow me to positively I.D. it? Please advise.

Thanx,
TNJB

In response to your comments I can state from the outset here I'm not playing games and I accept your apologies has you have misjudged. I did listen to the NAC A5 and we british tend to have our demos in Hi-fi stores. I found the cable a little cold and clinical for my tastes but I will take your advice, and borrow some and try it in the comfort of my own home, along with some interconnects. My intention was to report back to this forum if my problem had been solved and I will still do that.

Cunningplan,

I have just found this thread. I found some of the responses to be very unhelpful and down right rude, not the best introduction to this place where some useful (and much useless) discussion occurs.

My 2p worth.

Naim kit takes some time to run-in (many weeks). The effects you are hearing could be down to the NAP150 being new (you didn't say how long you have had it). Do you leave the kit switched on, as recommended by Naim? Demos in the shop can be misleading due to the burn-in etc. Did you borrow the NAP150 to try at home?

Do borrow the NACA5 and try it in your sistem and judge for yourself. Cables also take some time to burn in so check whether the cables you borrow are brand new or whether they have been used a lot.

With regard to the source, many here, myself included fall firmly into the source first camp. Garbage in - garbage out, better amps and speakers only tend to expose the short comings of lesser sources rather than making the sistem sound good.

You said yourself you cannot afford a new CD player but do try to make this your next major purchase. Naim CD players are very good (I've got a CD5 and have heard a CDX in comparison.) and when you do take the plunge, remember to borrow the kit for a while.

Hi Seagull
Thanks for your input this is the type of response I can relate to. My NAP 150 is approx 2 weeks old perhaps not run in yet,I do leave the kit switched on all day and off at night. I will borrow some NACA5 and check if they are new or not that seems good advice. I am of the belief that just because the manufacturer recommends something, that it should be read as gospel, doesn't always sit well with me. The dealer I deal with does not have Naim cable on their Naim equipment and there have been other shops I've gone to where they use different cable. As far as the source goes I intend to get a Naim CD perhaps sooner now than later I suppose my credit card will have to take a battering. I will perhaps ask advice here first before I listen and purchase. Thanks again

You should really leave naim kit continually powered up - day and night.

Hi Nigel
Just returned from my local dealer (sounds like I'm buying drugs) and he told me the same I have obviously have made a few elementary mistakes,he also told me to get rid of my surge protector adapter on the mains and use an ordinary one, sounds odd but I'll give it a try. I did e-email the owner of The Chord Company and he seemed to think the cabling was fine and it was probably something else,at least he didn't try to convince me to buy any new cabling Chord or otherwise.I'm just going to leave the system switched on for a few days and change my adapter and then play some music. I will report back in a few days.
Cheers everyone

Naim kit is very sensitive to mains quality (see the saga of Nick Lees mains problems - he has, on paper, a cracking hi-fi but because of mains problems he, and others who have heard it, say it sounds dire at times), you may find most of your problems disappear when you get rid of the adaptor (no promises though). Ideally you should get a separate mains spur (or spurs) for your sistem.

Well, yes, I was downright rude, and I apologize - this time with deeper understanding of why I responded the way I did. CP, if I had realized earlier how annoying I find cable discussions (which is my problem, not yours), I would not have flown off the handle. I think I'll be able to control myself in the future.

Meanwhile, welcome to the forum. Your measured responses to the sniping indicate you're likely to be a really positive influence here as you ask more questions and as you share your experience.

Here's why cables have become a pet peeve of mine.

Response to cable changes is so variable that I think it's fruitless to spend much time choosing them. I can hear differences in cables, but I can't always decide which is better. Besides, choosing cables requires use of analytical skills, while listening to music requires more than analytical skills.

What I see from cable-hounds is constant changing - that says to me that cable-hounds spend lots of time and energy choosing cables but remain dissatisfied anyway. So I conclude that spending time on cables has a very low payoff in terms of listening to music. I did not realize quite how annoyed I get about spending time on cables until this thread.

Meanwhile, Cunningplan, by now you have received some friendliness from the residents, and some good info - info that will delay, and probably prevent, a time, money, and energy wasting attempt to choose the best IC.

Personally, I think the main problem is turning the 150 off at night, but you'll have to hear for yourself if leaving it on raises your enjoyment level.

Regards.

Phil

Hi Phil
Your apologies as mentioned before have been accepted.It appears I've been a bit naive with the way I've attempted to tackle this problem, thats why I joined the forum to bounce ideas off people. The amp has been left on all day so far and will continue to remain that way. I will as promised report back in a few days when I start to play some music again.
Cheers
