I'm not a tube expert, but have tried several, including the VT100 mkII and McIntosh mono blocks. I have also tried many SS amps, including Levinson and Krell. My current favorite is the Pass Labs Aleph 4 (pure class A). For some music some tube amps sound better, but overall for any music, I found the class A Pass amp to produce the most natural sound from very low smooth clean bass to beautiful highs.
