Opened her up with some Rush ~ Exit Stage Left "YYZ (live)"
This an awesome Neal Pert drum solo that I've admired for many years.
The wonderful thing about this amp, is that it just doesn't seem to sweat anything. All the dynamics from every piece of kit stayed together without any strain or harshness. Last big amp I tried this out on was my PS Audio 200c. Still a pretty beefy amp, but with only half the output devices of this PL. Sure, it played loud, but ran out of gas on the top end (clipping). This PL is like.." Yeah, whatever, what else you got?"
I've been a bit surprised that it seems "smoother" on vocals, or should I say, more natural, than my lil KT88 based tube amp. However, since these are 901's I'm checking this amp out with, I'm going to have to guess that this big SS amp, with some significant damping factor, is controlling 9 voice coils per channel, with much better control. So, what ends up here is a better focus on every aspect of sound, which in-itself removes the edges, rather then a cover-up.
Every piece of music I listened to through this 700B sounded better in every aspect I can think of. Especially on giving each individual voice and instrument it's own place within the stage. Small dynamics, and all the big ones, were served up with nice focus, allowing you to hear individual character, rather then the amplifier painting on its own.
Now, you have to take my ramble here with a grain of salt. To each his/her own. But this is one kick ass, beautiful piece of vintage gear that I would be proud to own. It's sounds fantastic, looks amazing and is one POWERFUL motherfucker.
Cheers!
