new wet dreams OR where is the next fort knox

WOW ;-)


On saturday the 8th, i got the chance to
hear a naim av system at s.g. akustic in
karlsruhe germany (www.sg-akustik.de).
Here i was invited by Ulrich Hohn
(customer of sg) to
join the happening and afterwards hear
a few notes at his place.

Stefan Gellrich, the owner of the shop arranged
some drinks in the entrance hall (also
non alcoholics, so that one could
concentrate to music, and have the drink
afterwords for cooling down.)

The presentet gear in this AV-Demo was
the cream of naims top end products.
The SL2 where used as front Speakers,
for the rear in this setup nbl's have
done a proper job. Thomas (naim germany)
brought also the new naim center along.
(The center is a real speaker ;-), not a tiny
hideable shoe box.)

There was also one BIG Sub (sorry don't remember
the brand), but stefan quoted that here a
1kW activ amp was pumping in the room. And
more then earthshaking volumes where possible.

Ok, Ok, up to hear it's not that spectacular,
beside the sl2, well known standard equipment ;-).
If one could call nbl standard speaker in each
livingroom.

:-) topping that, i can ;-)

The DVD-Source was an expencive rotel player, down
the chain, the av2 feeds a 175 for the center and
the rear speakers.
the sub was driven directly from the av2, here
using the sub out which (somehow actively???)
provides only the deep frequencies.And hell the
REALY deep ones.

increasing the curiosity ;-)

the av2 feeds with it's unity-gain output
a 552 ;-) there it's out ....
i saw and hear one in flesh. a real beast,
delivered with the flash remote control...

hey naim could i change my flash (from cdsII)
to a pair of sl2's.....(kidding, even
cdsII is out of budget).

the 552 feeds a nap500, kicking the sl2's.

Now imaging us listeneres sourrounded bye
this enormous power and light green shining
new naim logos (independed of whether i like
them or not, in the dark the new black
boxes show an unbeatable attraction...)

We looked at some movie parts, and heard
i thought it was abbc dvd, with for
example susan vega, shinnead o'conner....

Marvelous, this maybe is the new child wet
dreams of today. So even the 552 was only
used with the unity-gain input, in combination
with 500 and sl2 it was an amazing experience.
there was thath much more information available.
(like jump from 72->52)
For a few minutes (thanks to stefan) we heard
a cdsII feeding the stereo part.
CDSII directly connected to 552, for shure.

On the naim charlie haden and.... , sorry
forgot the rest. (Bass and piano, offered also
on vinyl from naim)
It shows a lot more details and flow then i ever
heard from this cd before.
The high frequencies and resolution out of that
where in another league. Even the nbl's don't do
that. (So here the 552 must be the origin for that.)

Stefan also (again with dvd) showed us earthshaking
levels and demonstrated how LOUD sl2's could go.
And that was not the MAX on the volume pot.
Gosh, frightening experience.
They figure the sl2's capable of 100W music capability,
but nobody talked about the db reachable with that.

Thomas also showed us the assembling of the sl2's,
realy much easier then sbl's :-).

***

Dear naim what about dividing the prices by a factor
of 2 ....

552 is in different league, a more or less shure
home dem at ulrichs place will show how it works
in domestic environment.
As a stereo pre alone, and feed with vinyl.

sl2's... if driven by such a power and pre a DREAM.
here i like to get a home dem for selling my sbls
afterwords :-(

Additional to make the best out of the presented gear,
it was put on naim fraim. (undiscussable one of the
best racks available out there)

hope you all enjoy music (much more with 552's but the 72
still is a great PRE ;-))))))) )

naim keep on going

Hallo Mathias,

Sounds like you had a good time!

What did you think of Ulrich's whacky SBL setup (with the tweeter cabinet fixed onto the back wall)?

Thomas
Posted on: 14 June 2002 by M. Brandstetter
yes it was a nice evening.

And i saw your thread about the 552 (sorry,
have read only the first post up to now).
But as you quoted the 552 is a sweat new
toy ;-).

What about the division by 2 in case of an
552 order ;-)))))).

Jokes beside, it was great pleasure to
see and hear it. Interesting also the new
PSU for it. And the new sockets behind.

Is there a possibility that you'll ever build
phonoboards for it?
(poor non lp12 owners realy have dificulties
to mount a prefix somewhere, and the stageline
doesn't do the trick)

Hopefully you enjoy it to ;-), maybe if you
dislike the sound of your prototyp i'll nurse
ist for you a few weeks....

Ulrich's tweeter mount shows a bit of the sl2's way of reproducing the high frequencies.

In both cases, the direct coupling to the
inertial vibrations originating from the
mid-bass driver are minimized.

Of cause, the sbl tweeter is not the
same as in the dbl (sl2), so here you loose
against sl2.

Strange to put the sbl into parts, but it
works. (naim please don't read the sentence
before)

His lp12 also is a beast. It resides (sp)
ontop of a custom linke-pyramide, moded
in cooperation with linke himself (ulrich can
tell more about it then i).
Naimed LP12, with a special Ortofon Pick-Up
produced only for germany (ulrich correct
me if i'm wrong).
One amazing thing is that his lp12 setup
must be near ideal, touched it swings up
to 30seconds. Measurable by putting a mirror on
top of the player, directed lightbeam as an
indicator.

With this lp12 and activ sbl's i think that
one has a good starting point for a 552
evaluation.
If he got the chance, and i the possibility
to join, i'll post it.

Beside, not initiating a new LP12 threat here.
The normal lp12 i dislike (please no bashing for that, maybe i'm deaf; then judge the 552 statement
above like you will).
Ulrich's lp12 is the only known to me lp12 i can listen to for hours without problems. Here all style of music works, and this without the usual lp12 faults.

Here i can't judge whether this is caused by the
stand or his tweeter mount.

You guys are absolutely bonkers. Your writing sounds like Jodie Foster in "Contact", telling everyone how she's just been to another world as they gaze at her in disbelief.

why?

would you believe someone who tells
you that a lp12 swing 30seconds after
fingertipping?

my old thorens made a few up and downs
and that was it.

i don't now whether this is a pro lp12
or a bad thing. nevertheless i didn't
believe ulrichs word in that. thereafter
we measured it.

have a nice day, and take care of the
purple people.

Thomas,
It was the realization from Naim that the tweeter is to be decoupled as well as possible from the bass. I decoupled the tweeter only better than Naim had succeeded with the SBL.

Mathias and I heard the SL2 only with the NAC552. We can say that the NAC552/SL2 goes better than my NAC52/SBL. Whether the SL2 sounds better than my SBL I to judge will only be able if I heard the SL2 with a NAC52.

BTW, Paul Stephenson said in September 1997:
"I cannot see many people wishing to re-arrange the hf box and bolt it to the wall!"

After 5 years I can say, he was right absolutely. But if it is correct for better hifi to strive, then I were right also.

Guys, decoupled tweeter marvelous music makes. As soon as possible the great SL2s listens to you.

I had a look at your technical drawings some while back and briefly considered trying it out, but I'm not very skilled in that respect and I didn't quite understand the drawings - maybe some time in the future when I've got less work ... The concept certainly seems to make sense (even to me).

Hi Thomas K, the topic here the new SL2 and the NAC552 should be. I suggest therefore that we inform ourselves by email.


Dear Mr. van der Vegte,
your demo showed that the SL2 with the NAC552 is extremely high-quality. It showed that the SL2 goes by far louder than the SBL. The demo did not show, how the advantages distribute themselves on the two components. I hope to be able to buy in approximately 18 months the NAC552. Or do you recommend to me, instead of buying to its the SL2?
One excludes however the other one - always.
Besides, your SBLs and my SBLs are two different things.

Regards
Ulrich

dear thomas
so, you had the sl2 at you place?

what did you think about it working in your
room? for my room sbl fit, a bigger box
i can't imaging working there.

so if the output is similar to sbl, maybe it works. a nbl or dbl won't fit (not the
speaker the roomsize would be the problem here.)

as thomas quoted, i also think
that you will gain the biggest
improvement by swapping 52 against
552.

just imaging if the psu realy betters
your prefix-scap. (that must be more
then a dream).
This you have to solve in a home dem.

Here another question occured to me.
Thomas, or some one at naim, how long
does the new 552 need to warm up?
The 52 at least is back to balls after
about a week.

Take care about the purple people ;-)

Thomas van der Vegte,

A home demo would please me much. Beautiful it would be also to hear the SL2 passively. If the SL2 should go better than my SBL actively, could I unite devices to sell:
2*NAP135,SUPERCAP,SCAIC18(black) ,SNAXO2-4,SBLs,PXOs!!

Naturally that has all still much time - a quantity money is to be saved.

Ulrich
