Hi Emil,
Thank you the speakers play music with such refinement and ease, but are very dynamic and lively at the same time. They are very efficient and only need a few watts.
Didn't try the 300b's yet want to get some more hours on them.
I'll tell you the Pass Labs is no slouch! The bass is awesome such control and power with smooth open mids and treble.
I think the SET should have more purity and openness in the midrange. I'll put them in next week.
Once everything is dialed in, I would like to have a few Guys over. Not a full blown rave , but I can fit more people in this one more then my old one.😉
