Bypass preamp, better sound, yet fatiguing?


Does anybody know a good reason why running from the CD player direct into the amp will produce a better, detailed sound (e.g., piano sounds more real, instruments are better separated), but on the other hand, after a while, after an hour or so, the sound becomes fatiguing?

Is there any thing as too much detail?

System consists of Levinson 390s, 380s, VTL MB-450, B&W 802n. Interconnects are Transparent super. Speaker cable is Transparent super bi-cable.

Are the cables not up to it? Room acoustics? B&W tweeter to bright? I don't experience any fatigue, if I listen through the preamp, but the sound is somewhat duller (but better rythmically) than if I go direct. Any suggestions are welcome.

Jsadurni, it appears that you like to tweak quite a bit and that's good.

However, from where I sit (in Salem, OR), it's difficult for me to see if you have any serious benchmarks in which to compare your tweaks.

I've heard one very authoritative source state that isolation transformers have their own pitfalls and in general are no match for excellent line conditioners. But I'm out of my league as to the whys and wherefors. The fact that you seemed to experience some positive benefits by plugging straight into the wall would seem to substantiate such claims. The other problem is finding line conditioners worth owning that do not induce their own sonic harm. In my experience the most popular brands actually sound worse than plugging straight into the wall.

As for the ics and scs, I'd highly recommend acquiring some Speltz anti-cables and anti-ics. Speltz' anti-cable speaker cables cost $10 per foot, the anti-ics cost $100 for 1m pair and are the second best cables I've yet heard. Moreover they require essentially only a few hours burn-in time and they come with a 30-day satisfaction guaranteed or your money back.

These should give you some good benchmarks for your other cables and they induce little to no time-smear. You probably are aware that some to many ics and scs induce much time smear which in the highs produces a digital-like noise or hash and induce much ear fatigue. Time-smear in the lower bass regions simply make the bass sound wooly, loose, bloated, ill-defined, etc.. Anyway, the Speltz' cables absolutely minimize all of these ill affects and when the anti-cables are elevated at least 1 or 2 inches off the carpet, they will sound even more pristine and with greater speed.

In my experience and almost without exception silver cables/ics without the best line conditioning simply accentuate any fatigue already present. And that's assuming the silver ics/cables offer good sonics to start because there's plenty of poorly designed silver ics just as there are copper.

Thanks for your response Stehno, you were right on the spot, I changed speaker cables and things got a lot better I finally decided on the Cabasse original cable which looks like your every day lamp cable but it has diferent color strands (whitish-blackish), I guess its all copper, but it brings out the best on my speakers, I guess they know what they are doing!
10 inches of speaker cable and the Fatigue is gone....

I also returned to my Isolation transformer, when I hooked it back on I could not believe the change, two blankets were taken off each speaker!! It makes the sound of my system.
Going to the wall outlets made my system "undetailed" lost dynamics and extension...?¿?¿?

Thank you Tvad, amazing, I would have gone for the previous set up, but I am sure the new one sounds better then... interesting!

All the best
