To ghdprentice:
My system is as follows.
CD player Musical Fidelity A3.2 CD (made in 2003 in England)
Turn table Sansui SR 929 (Denon DL-103R)
Preamp Onkyo Integra P304 (ca. 33 years old, Japan)
Power amp Yamaha MX-1 (old, old, 200 watt per channel)
Cayin 860 mono blocks (4 x EL 34 each)
Speaker Vienna Mahler (120 lbs each)
All cables Monster (interconnect, speaker)
Vol. Control SCHIIT SYS
---------------------------------------
I don't use the Onkyo as a preamp any more, but use for only phono section.
I used to own CJ tube preamp, Plinius preamp, Brystone Preamp, Jeff Roland preamp, etc. But the onkyo does its jot close to the preamps by 90-95%. So, I sold all preamps, keep the Onkyo only. Actually, 2 years ago, I purchased the Onkyo P304 one more from ebay. I used both Onkyos. I made one Onkyo as one channel combining two channel using mono-making Y-cable. Anyway, using 2 Onkyos, S/N (signal to noise ratio) was better, but I found no advantage regarding sound quality.
Using the SCHIIT vol. control as a passive preamp, I found my music became a lot better.
(1) Mid - high very clear, not shrill, not analytical, just like piano is playing in front of me, Trumpet = I could hear metallic feeling just like when I was in high school brass band,...
(2) Bass exaggerated booming is gone, but true bass from the source was heard. If you like some sound (boob, boob, boom), then I can not discuss my feeling with you.
(3) True to the source music less component means less additives to the sound. So, if the source music is great, I can feel great. If not good, I hear un-musical sound.
I can still remember that Herbert von Karajan said music from CD player was better than that of turntable. He mentioned that to engineers of CD player-developing, 1980s. At the time, so-called audio reviewers said the CD music was so analytical. I think the reviewers barely attended actual concerts, compared to Karajan. Karajan was involved in CD format such as how many minutes in a single CD, etc. I believe Karajan preference (favoring CD against analog) simply because he spent a lot of time in actual performance, not because he was a very famous conductor.
We have to spend many $ to buy expensive gears.
Expensive power cable = I think this is the most unnecessary item.
