I am a broken record on this, but, the integrated tube amp that I am a BIG fan of is the Synthesis Audio A-40 (40-watt, pushpull, KT-66 tube). It comes with a killer good DAC included
I agree with the above statement. I have a Synthesis Audio A-40 that powers a pair of Audio Note speakers and the sound is just sublime. Feel free to PM me if you would like any additional info.
