To the OP, you could "Put your money where your mouth is." With all the brew-ha-ha about tubes, I went out and bought a Melton P/P KT-88 tube integrated rated at 80 WPC to see how it compares to my 20 year old Yamaha RZ-Z9 in "Pure Direct" mode. The Yamaha is rated at 170 WPC with dynamic power to ~540 watts at 2 ohms. My source is an Oppo95. The speakers are of my own creation and include an 18" JBL 2241H, a JBL 2251J 10", and a modified Great Heil. Personally, I'm a stickler for detail and with well under 100 hours on the tube amp, I don't even listen to it in favor of the Yamaha.
I don't give a damn about what people say about Youtube videos. Get a set of good monitors or use good headphones, and you will hear the difference like night and day. The tracks were matched to within ~0.2 dB.
