I have a couple of tube amps/solid state amps & I occasionally mix n match them. Solid state and tube stuff do sound 'good'.
BUT, I found that once I had ALL amplification stages running tube (as in my arc ph-3, bat vk-5i, and arc vt100), you take a pretty big jump. All of a sudden the music is REALLY alive with the full-on tube magic. To date that is probably the most engaging system I have.
It doesn't have a wisp of the ultra-resolution that I get from SACD's on my SCD-1/Aleph P/Aleph 2, but definitely more 'alive'.
Swapping a single solid state component into this rig ruins the vinyl playback. Wish I could get my CD's to sound so good...
Anybody out there find a similar effect with a tube cd player ?
