running in nac552, some questions

Nick Lees:I think we should give our non-anglophone friends a laugh and insist that all posts be written in German, French or Portuguese (or whatever) for the next week or so!

Dein idee ist ausgezeichnet. Vielliecht ein faden fur sprache in die zelle von polster?

My dealer came up with the following; allegedly from one of the techno guys at Naim:-

To 'run-in' a new amp quickly; one needs to switch it on for 30 seconds, then off for 30 seconds.

ONE HUNDRED TIMES!

I kid you not.

Ulrich

Congratulations on the new amp!

Can you tell me if you have undertaken more tests of the prefix powerd by 552PS against the supercap/prefix combination? Do you still prefer the 552PS?

Thanks

I recall that Ulrich preferred the 552PS powered Prefix to Supercap power, it was my dealer (and Roy George at Naim apparently) who said the 552PS powered Prefix was better than using a Hicap but still short of using a Supercap.

The other issue is whether powering the Prefix from the 552PS compromises other sources as happens with the 52

Let us know Ulrich

Hi Ulrich!

Does your NAC552 sound now as desired?

Is there a trick to tune the performance like checking the subchassis or something else?

Regards, Schiller

Ulrich,

and what about your CDS3...?

With *dozens* of 552s ready for shipping, it would be interesting to speculate the kind of demographic they'd be destined for. Hmmm, maybe pop stars, footballers, oil sheiks and postmen...

Andrew;

A friend of mine has a 552 on order. He's a contributor here and probably won't object to me calling him an ordinary bloke.

I think you'd be surprised at the number of 'regular guys' around who are able to purchase such expensive toys.

Thomas!
I have heard tt about 3 hours every day the first 5 weeks. That are 100 hours.
(I have no CD). My dealer has now make an adapter to connect the tuner to socket 7
of the Nac552. Each day brings now 24h music into the tt-input. I think in 4 weeks the tt-
input will be runin.

"Does your NAC552 sound now as desired?"

At the home demo I have heard the SBLs in active mode. - now I hear my SBLs passive.
The SL2s were at the home demo much better than my SBls passive.

Regards, Ulrich

Richard - think laterally, if you can get a decent discount say 10% from the dealer then get an unsecured loan for about 7.6% apr which will be similar amount to the discount.

See the Intereactive Investor site for some loan details

However if you were jesting / dreaming...

Perhaps Naims next product line will be Loans for Hifi....

Thanks for your reply.

I was interested in your experience because I had a 552 at home for some days and was disappointed of its performance.
I was awaiting a big step forward of my existing 52 but at first I was hearing a tamed version of the 52: the 552 was well-behaved, no booming no harsh no sibilance etc. but also no thrill no involving not the usual attack. After three days it was getting better but not very much. After my complaining the dealer checked the subchassis and some other details which helped a little bit.
Two days later the performance was still becoming better but in very tiny steps. After 5 days I had to return the 552. I can say this 552 sounded better than my 52 but for me it is not worth the money.
I know that this 552 was well run in (it was demonstrated at different occasions in Germany)
but nevertheless it needed some days at my home to reach an acceptable sound. Maybe a 552 needs weeks or months to reach a top of the world performance. Therefore, Ulrich, please inform me if your 552 is still developing.

For better understanding: i thought and wished the 552 would be a no-brainer like the NBL substituting my SBL, the SCAP substituting the HICAP for the SNAXO or the NAP500 substituting my 3 NAP 250 of the active driven NBL. In this cases hearing was wanting and buying the new gear.

But I don´t give up and keep an eye on comments on and experiences of the 552 because this should be - in theory - my next desired upgrade.


P.S. In the meantime I bought an AV2 which is much better than my old processor (in-build the DVD-player Panasonic 360). This upgrade, in my opinion, brought so much more fun and pleasure i could never get with the 552 substituting the 52.

Regards, Schiller

Dear J.N. and Andrew, I've just spent around £13,000 upgrading my kit this year and if I spend £1 more, my wife has assured me that I can look forward to spending the remainder of my life alone. I have an appointment with my local dealer on friday!!(only joking dearest!!!)

Thomas!

I am not unsatisfied. Since 9 days socket 7 is connected to the tuner and my 552 has started to develop.
But the prefix is disconnected while the tuner is on socket 7. Therefore the prefix work not really well.

"I had a 552 at home for some days and was disappointed of its performance."

My home demo was great. That is my problem, I have heard it in context whith the SL2 much better.

"i thought and wished the 552 would be a no-brainer like the NBL substituting my SBL, the SCAP substituting the
HICAP for the SNAXO or the NAP500 substituting my 3 NAP 250 of the active driven NBL."

The NAP500 substituting my 4 Nap135 was less than 552 substituting my 52.

If your source is excellent and if your separate spur is 10 sqmm than make a demo with 552 AND SL2.

Regards, Ulrich

552's selling well! That's an astounding statement for my ears (depending on what that actually means for an £11,000 pre-amp)!

I believe I am an ordinary bloke, reasonably well paid (I think), no kids, and I do not envisage a 552 *ever* being in my sphere of affordability (I do hope to be proved wrong!). 11k on *just* the pre-amp !!! <faints>

I have sold my 52, 3*Scap, Snaxo, 2*Nap135 and have no car buyed.

Ulrich

Ulrich,

it´s time for a serious downgrade and buying a few CDs...

"it´s time for a serious downgrade and buying a few CDs..."

I did not hear ever chamber music and jazz of a CD player, which sounds approximately in such a way as in the concert hall.
Perhaps there is someone in the southwest of Germany, who can show me that it is possible.
If there were already sufficient SACD Naim would have probably also a player for this in the offer.

There are the buyers of CDs, those that prevents!

Ulrich

I think my seperate spur is only 3,5mm².
So i plan to change it.
Which wire do you use?
The type consisting of many fine wires (is it called stranded wire?) or the type electricians are using which is only one solid wire?

Regards, Schiller

Thomas

I use the type consisting of only one solid wire. But I have no experience of such
stranded wire.

Regards, Ulrich

Thanks, I will give it a try.

Schiller

I heard 5 weeks long for approximately 2-3 hours daily tt. The Prefix was to socket 7 of the 552 attached. Afterwards I had not yet as good music as on the home demo.

My dealer made then an adapter cable for me. Hereby I could connect socket 7 of Nac552 to the tuner. Socket 7 was now 24 hours daily on signal. In distances of 4-6 days I heard then again improvements. The last improvement I heard 25 days after I have connected socket 7 to the tuner.

The distance of a brand new 52 to a brand new 552 is many smaller as if both are brought in.
Perhaps does therefore longer time need the 552?

Ulrich

I have found the 552 to take much longer than the 52 to run in. Please keep me informed.

Try a few dealers - my own dealer did offer IFC - whether they still do remains to be seen. They are a Naim dealer, though I don't know if you'd get an IFC deal up to the value of a 552. In some regards, if you can negotiate a discount then that makes perfect sense instead of an IFC deal which would undoubtedly eat into a dealer's profit margins. I think a secure sale at 10% off might work out just as good for a dealer as a 2 year IFC deal at full rrp. Then again, I may be wrong...

After 10 weeks I thought now is the 552 ready - but 6 weeks later it was better again.


3 weeks ago I could afford the NL2. They are approximately run in. I would have never thought that I can hear my lifetimes still so well hifi.
