Has anyone else ever reached an audio impasse?


Perhaps I should explain -

A friend of mine has a VERY high resolution system which would retail close to the $100K mark. Each component upgrade he has made over the years has been based upon comparison between components. He has built a fantastic system.

Now here is the problem -
Recently he and I compared his source CD player which is the top model currently available under 15K, against a Sony 9000 ES SACD/DVD player. We A/B compared them.

After extended listening, we found the differences to be so minor that it was difficult to detect which was better. We did the comparisons with Redbook CD vs SACD, RedBook vs. Redbook and still the 15K CD player was only marginally (.05%) better.

The 15K CD player had better more expensive interconnects and power cords than the Sony which was using a stock power cord an old Audioquest Topaz (cheap) interconnects.

In previous listening sessions over the past year we had compared the same Sony 9000 CD/DVD/SACD player against MANY other CD players ranging in price from 2000 all the way up to 7000 and on redbook CD's the Sony always got it's butt kicked! It sounded hollow - with a recessed midrange - electronic - over emphasized highs, etc.

Then - I took a 100 Toshiba DVD player to his house and tried it against his 15K CD player. It sounded the same as the Sony. In fact, the 100 Toshiba sounded as good if not better in some ways than the Sony DVD player but...still was .05% out classed by the 15K CD player.

With each source component in these auditions, the soundstage remained VERY large, images were perfect and tonal balance couldn't be better. The subtlety of the changes between the various source components would be best described as perceived rather than actual.

I am curious to know if anyone else has experienced this type of an impasse. I know the $100 DVD player should not sound like the 15K CD player (at least it never did before)
but it does now. Why??

Could there be a bottle-neck somewhere? Could the character of an pre or amplifier be so strong it restricts performance of a source component? What could cause this to happen?

Help please...

This evening we removed an AZ power cord from the preamp.
We had forgotten it was back there.

Anyhow - when we removed that power cord from the preamp and replaced with an NBS Statement, things started to open up. We were beginning to hear differences between the CD12 and the $100 Toshiba DVD player. Actually - we heard significant differences. It's amazing how that power cord really disguised things.

Another thing I noticed in this recent audition of many preamps is that the more liquid the preamp, the less inner detail seems to be resolved. Has anyone else ever noticed that? Presuming liquidity is textureless sound, inner-detail often presents itself with a slight texture.

Differences in various CD players are at times subtle but I have found that the best CD players have a certain way of presenting inner-detail which is better than low end CD players. For instance, my Mephisto II is as analog sounding a CD player as one could hope to get (tonight it bested the CD12!) But most of those characteristics take form within the domain of inner-detail.

The liquidity of a good tube preamp seems to diminish the texture required to present the inner-detail hence removing the character of the CD player and thus making it more difficult to notice subtle differences.

I figure this is why the cheap solid state preamps were capable of conveying more of each CD players true character.

The flip side of this is that the cheap CD players which typically sound hollow, have limited focus, are harsh or electronic sounding, benefit tremendously from the better preamp as it will mask the nasties with liquidity.

Make sense?
I considered too much liquid as coloration. That's why I misunderstood Supratek Syrah as a SET power amps.=> SET preamp & SET amp.= too much liquid!? Without auditioning C-J's ART, I was not aggressive to say ART was not neutral enough. Especially stereophile & HP from TAS like ART 2 so much. A passive preamp from EVS or Audio consulting's silver Rock will present you inner details. EVS Nude Attenuator is better than Silver Rock only in terms transparency maybe because reduction of one set of interconnect cable. Silver Rock is better at more consistent dynamic, inner harmonic detail, timeless experience- I don't know if you & your friend have ever had this kind of listening experience.
I spent the better part of the afternoon at my friends house and I can say that with the new dedicated power supplies (one for analog another for digital)... his system has transformed.

Earlier this week we were disappointed by the poor bass performance from tube preamps vs. a Krell HTS home theater processor. Today - I take those gripes back. The Supratek Syrah preamp has better bass (and more realistic) than any of the other preamps I have tried thus far. While it is still liquid and involving, with adequate power, it was ultimately better detailed (GOBS of inner-detail) and portrayed the music in a way I have never heard before. This really makes me want to upgrade to the Cortese since it must be the only preamp out there which can beat the Syrah. The ART is a good preamp but seemed so...dull and lifeless by comparison.

Once again the differences between sources are now VERY easy to detect. I feel almost ashamed of myself for questioning the equipment or the validity of my past decisions.

The problem in this case was not my ears, it was however the simple lack of power.
bwhite: thanks for all your followups. it is often amazin', isn't it, that one, seemingly simple thing can affect the sound of a whole bunch of components. your's is an experience that can teach any number of lessons. it's been interesting for me to be following the saga. -cfb
bwhite, I must underwrite everything cfb has said and wish to thank you myself for all your followups. I've learnt a lot from the unfolding story and am personally glad than all is now well
