They look identical to the Consonance Ciber 300 B PSE, had the same valve compliment and I had to check the wiring to be sure, but yup, they were PP's. Damn. "No worries says Mawei at Opera, would you like us to send the PSE instead?"

Cue lightbulb hovering over jaded part-time hi-fi scribbler's head:-) "Er could I keep the PP's as well so I could do a true back-to-back, PSE vs PP?"

Yessss!

So not only do I get to play with two sets of very nice amps, I also get to answer a question that's been bugging both me and a lot of other hi-fi nuts...
