I only hope I will not bore you guys to death, but here it goes.
Long time ago while living in Poland I used to have ProAc Studio 100 with Electrocompaniet ECI-2 and Arcam 6 player. I know nothing fancy, but sound for me was excellent, bass was not low but was fast tuneful, I had fast transients, nice micro and macro dynamic. Music simply was alive. I have moved to Âapartments north from Phila (I still did not figured out why they are called this way, apartment in Europe means luxury flat not lousy barn from paper..., how true apartments are called  super apartments squared ?). Now I could afford bigger stereo so I have bought Thiel 3.6 and MF A300 (IÂm using the some player). I was expecting better sound. But it was not the case, voices were dead, transients from big Thiels was nonexistent, dynamic in micro and macro scale was nonexistent. How so big speakers could sound so anemic, lifeless ? I just could not understand it because I had audition small Thiels 0,5 while in Poland and they sounded really good to me, they was to expensive to me though ($2000), I have bought Thiel 3.6 for $1800 here :) (Wadia cost 13k$ in Poland and there is no second market for it, AudioAreo Capitole new cost about 7k$). So problem must be somewhere else. After a while I have figure out that paper walls and power mains and L shaped living room with kitchen are to blame. So I figured out I will have to recompense it by buying much better equipment. I changed source from SACD SONY (9000ES) what a downgrade it was - wrong path  think again - this time harder. Next I tried to replace MF A300, so I bought Clayton M100. A little better, stronger bass more liquid sound but still not there. And there is Âdeal of the century threadÂ. I did not believed that preamp would matter that much, but it was my last resort, what I got to lose (nothing - no maybe 3k$). After half year of waiting I got it. I was afraid to turn it on to not to be disappointed again. But I have gather my courage and:
first impression with stock tubes was very very positive, I finally disconnected my MF A300 (was using it as pre with Clayton), there was music again, nice rich vocals, liquid sound, even stronger bass, but the most important - sound was alive again like it was years ago. I was really moved. Even BMG CDÂs are now listenable. So even lousy power mains in my Âapartment (when my wife is ironing bulbs are blinking like Christmas tree) were not able to kill Supratek spirit that good it is. How preamp could make such difference (cdp, power amp could not do it) I do not know. I just cannot imagine and wait when some day I will be back to my 1.5 feet wide brick walls in Poland and will connect it to decent power mines. It could be really something. But for know this is my first not SS component. IÂm trying to improve it by tubes rolling. So far I have changed to Ken Rod Black Glass VT231 and Philips Miniwatt, there is a difference vs. stock tubes but it is really small, maybe will be bigger after cdp upgrade, and IÂm sure will be huge after barn to true apartment upgrade :) so there is a lot for me to look forward.
