Was up early and drove over to Canada nd picked up the amps from a very kind elderly audiophile. I made it home, unloaded and got the amps unpacked, set up, connected and ready. After a brief delay for dinner, I followed the procedures to check the tube bias. After two small adjustments, all was ready to go. I have to say, I had allocated an hour and a half of listening time, and that just went completely by the wayside. These amps are simply superb. What I was listening to before was already at a very high standard, but it's difficult to find words to describe what the ML2's have added. The notes just hang in the air like stars. The soundstage was outstanding, bass was absolutely dead on, treble was that of the purest bell I could imagine. The overall experience was magical. Fours later, I just stopped here to report on my experience, and thank all of you for cheering me on for this purchase.
I do have a question, though. I've read a number of comments saying that tuberolling in the ML series is pointless. That makes perfect sense, as there is no tube rolling with 6C33C's being a single production tube, and 6NP's having no real alternative either. But I have also noted several people who advocate getting a pair of the best 12AX7's that you can, because they do have a significant impact on the sound. What is the truth? Thanks.
