hi, thanks so much for your valuable input! after reading your comments, i believe anyone reading in here would agree everything you mentioned. I'm thankful that you shared your knowledge and explained it very well. Of so many reviews (even from highly respected reviewers in AV mag)that i had read, none of them had given such an insight!
i listen to most kinds of music, from Beyonce, K-pop to Full scale cinematic overtures eg.Battlestar Galactica, Val Hellsing & ERA(songs eg THE MASS, I BELIEVE), Engima (especially with real orchestrial recordings) except jazz, chamber music nor vocals.. you get the idea? that's also why i prefer panals, for large scale use! Youtube have many of those tracks to sample..
i'm so eager to hear your other comments. do you think M275 can power my kind of songs? i read from somewhere M275 is special due to its Unity Couple circuit topology, is it an OTL amp? do DHT amp need ancillary power filament current?
