I've decided to sell the lot

Posted by: Rockingdoc on 24 December 2007

Finally, after more than twenty years faithful membership of the Naim club, I've given up. My system has just become too shouty for me in the upper mid-range.
It's a an olive active system with CDS2,NAT101,52,SNAXO/HiCap,250s, SBLs fed mainly by a prefixed LP12. I've had it ALL serviced and re-capped (at great cost, I might add). For the past week I've tried everything I know to make it sound better; cleaned all the contacts, fitted new mains sockets, replaced fuses, dressed cables, tried all FOUR walls for the speakers.
The main effect was to give me a strained back, many areas of the sound did improve, but it still sounds shouty and a bit tiring to listen to.

I think the problem is that I now spend about two hours each work-day listening to my headphone system comprising a decent CDP into a Tim de Paravicini EAR HP4 valve headphone amp using Senn HD650s or Grado RS1s to taste. To me this sounds brilliant and I think this has made me a better listener, and now I'm bothered by the shouty nature of the Naim in a way that didn't bother me before.
The other possibility is that my hearing is changing with age. I'm definitely a bit more deaf than 20 years ago, so the volume is set higher, but I wonder if taste in sound changes with maturity? I certainly seem to drawn to the warmer round-earth camp these days.

Why not uprade? Well where would I go? A 552 is way beyond my resources and I can't see what else could help.

I suppose this is a Hi-Fi entry really, but I've never seen a thread bumped in that direction.

Dynaudio Contour S3.4s are another wonderful and smooth-sounding speaker that will let you hear your system to their full advantage. Sadly they've hardly been spoken of in the press etc since their release about 4 years ago. Work great with a 282/200.

Doc,
Hang on to your kit until you have identified a system which you know beyond doubt that you like better. There have been some xcellent suggestions here, another might be to downgrade rather than upgrade. The CDS2 should not be shouty and I wonder how it would sound through a Hiline/122X/FC2X/150X with n-Sats and an n-Sub or Piega TS5's.
Your hearing will not necessarily deteriorate much with age. I have been very pleasantly surprised that my hearing is still good, even now I am in my seventies.

Doc,

I had SBLs and would change speakers first at your place. I know exactly what you hear. They are far too forward sounded speakers. For the same reason I am listen to Grado RA-1/RS-1 at the moment. Sources are CD5 and LP12.

Good luck,
Oz

I'm back, after a brief spell of being unable to access the forum.

Following the above advice, I have been experimenting before "selling the lot".

Here's the test rig;

Pair of circused/lingoed LP12s, one with late Ittok+Ortofon Rohmann into Sugden Masterclass Phono stage, the other with Early Ekos/Expert Stylus Troika into Prefix.

Naim NAC52, Sugden Masterclass preamp, Audio Analogue Bellini pre.

Naim NAP 250 (choice of two), Sugden Masterclass powermasterclass, Sugden A21 power.

Naim SBL, Kef 103/4 , Tannoy IIILZ III LZ

All combinations tried, and initial findings are that the producer of the sound I dislike is in order of shouty;

1)old Troika/Prefix
2)NAC 52
3)SBL
4)NAP250

Changing any one of the above components improves the overall sound to something I could live with. Changing just the Troika but leaving the Prefix in the chain is still too shrill and shouty. (The Prefix has been just run in since a service and latest Snaic). It is important to say that changing out more than one Naim component (apart from prefix+52)begins to move the sound too far in the opposite softy direction.

So perhaps the whole lot doesn't have to go, but my main concern is the NAC52. Changing that for the Sugden improves the sound by a huge amount, but obviously this excludes the Prefix at the same time. Changing the preamp seems the way to go, although I have never heard others complain of a shouty 52. I really can't afford a 552, and my dealer suggests that the difference in sound between a 52 and 252 is minimal. So how would you procede?

I would never have bargained on the 52 as a weak link. Interesting.

How is your 52 powered, Scap or XPS? Has it (and the power supply) been serviced? I wonder if a friendly local dealer/forum member would like to lend another 52 just in case yours is a 'wrong-un'.

Happy New Year BTW

Of your options, the easiest way forward would seem to be to change cartridge - to the Ortofon you tried or maybe a dynavector. Either could run into the 52's internal boards. If that was still too shrill, you could simply get a new phono stage?

The sugden amp is clearly different to the 52, and you would certainly need to take your time to ensure that it really is better for long term living-with, rather than just a change, if you decided to go that way. I presume the sugden produces signal of the right level etc for the 250s. I may have missed this above, but have you set the system up passively to see if that works OK - the issue could be in the active components.

Happy New year chums.
Running in passive mode to reduce complications. All of the above gear is mine already; the Sugden system supplies our large open-plan downstairs where there is are a lot of glass walls and doors. Hi-Fi is never going to sound good there (dealer threw his hands up in horror), so this is a party system (pretty bloody impressive this New years Eve) which also feeds the garden in summer.
Listening room is small and upstairs, and has the Naim system.

The Supercap is freshly serviced. I'm sure Naim don't make Friday afternoon "wrong-uns" Winker. In fact, Paul Stephenson told me that every NAC52 sounds exactly the same.

Having had a chance to cool down, I wonder if a lot of the problem is the Prefix/52 thing. I hated the 52's internal phono boards from the outset, and went for the Prefix as the best Naim had to offer. I have never done a direct phono stage comparison in the Naim system before.
The Sugden Masterclass phono stage (cost about 1K GBP), simply blows the Prefix away. This begs the question, why have Naim risked losing customers by having a top of the tree phono/pre combination that really is pretty crap. I know the new phono stage is nearly here, but did it really take 30 years to get right, and how much is it going to be, and will it need a dedicated Supercap?

Anyhoo, next plan is to not throw all my toys out of the pram just yet, and audition a 252 using my Sugden phono stage and Ortophon cart.

I think this sounds a very sensible and well-thought-out course of action.

The voicing of the newer range of which the 252 is part is inherently less shouty. If the comparison 52-252 is anything like the 82-282 I tried as a matter of interest, there will be quite a difference.

I agree about phono stage - my Naim offering is long gone in favour of a DV P75.

Is it first worth trying the Prefix into the 252 to 'get your bearings' before changing source?

Have fun.

Thanks James.
The advantage of having a matching pair of LP12s is that I can try both together.

doc,

Your planned investigation seems good to me.

You have identified the 52 as a possible weak link so try the 252.

You have identified the phono stage as a possible weak link so try another phono stage. In this respect I would consider Naim's new Superline, reported elsewhere on this forum as due out at Bristol with a price tag of £1,500 (upgradeable by adding hicap or Supercap), or try Linn's Linto, or any of the other well-known offerings mentioned on this forum from time to time. Grahams have always advised me to stick with either an all-Linn cartridge/arm/phono stage/power supply or an all Naim arm/phono stage/power supply (with suitable cartridge)- seems sensible.

In addition to the above, I would be inclined to try a 300 power amp. The 500 ref amp preceeded the 552 by a lot of years and to my ears reduced the "shoutiness" of an Olive system quite considerably, The 300 is out of the same stable. Your 2x250 + Snaxo/hicap + £2k could well procure a pre-owned 300, if you found the 300 solved your problem.

Of course, there are lots of other things you could try, but............you have to somehow retain your sanity, so I'll leave others to add to your list with their pet solutions.

Cheers

Don

Thanks Don, the 300 was my second plan of action. Of course this is already taking me into spending territory that I was trying to avoid, but I think I'll also chop in one of the LP12s and the Prefix, as it rarely gets used downstairs.

I think I'll therefore keep the Sugden phono stage in my Naim system long term. Slightly quirky perhaps, but it sounds good, and has infinitely varible plug-in loading options.

Not yet. You're just going to be listening at first, to see if your problem CAN be solved.

Auditions are afoot, and am already WAY over budget. No surprise there then.

Hi Doc,

I went through a similar period of dissatisfaction with an active SBL system, some years ago.

A swap to a more humble new-syle-Naim-kit passive system worked for me. The musical presentation was more consistent and enjoyable with protracted listening sessions.

I've since climbed up the passive system Naim ladder, and am very happy with the sound I have now.

Our tastes (and hearing) do change - so roll with it. As ever though, throwing money at the problem is not always the answer. Sounds like you now simply want something different.

Good luck.

John.

Rockingdoc--

What are you using for racks?
Posted on: 12 January 2008 by Tuan
New speakers I would say. Try some models (non-naim speakers).
