Well, after quite a bit of waiting, I finally got my tube amp last Friday. "kind of blue" on SACD was the first SACD I bought (although a few SACD sample CD's came with my Sony 555)
Anyway, that's one awesome CD.....though I do hear some hiss.
As for the amp, it sounds good and it looks cool. But I'm not blown away. Maybe my ears aren't as good as some of these true audiophiles....and maybe; just maybe...that's a good thing. The amp sounds better than the SS I replaced it with a low to medium low volumes. Can I hear things I never heard before? Yes. Does it make me more critcal of of the harsher highs in my old solid state gear. Yes...but with a caveat. To me, those really harsher highs only become really apparant at high volumes. At high volumes with the tube amp though, the sound seems to get muddled...sluggish...distorted. I'm not sure of the best description, but I know I'm not crazy about it. The bottom line: if I want to listen to more accoustic type music at lower volumes, I definitely want the tube amp. If I want to crank up some hard rock, I'll probably just walk into the media room and play it on my HEC's RF-5's
Actually, the best sounding CD I've heard on my new setup is not an SACD. It's "Sweet Tea" from Buddy Guy.
