Had to mod the input of my X250 and thought you guys would like to see what it looks like...
Is ClassA worth all the trouble for a recording control room.
That review says, it is heavily biased into ClassA mode and has +/-47volts
Pass states that the X250 has a single-ended balanced design. Normally, these two terms are mutually exclusive, so here is a way it might be done (diagram below).
I'd say it depends on a lot of things. For an amp designer like nelson Pass, I think it can make a diff as he's good enough to squeeze everything out of it.Is ClassA worth all the trouble for a recording control room.
This is what it says on the site:The review also claims 250w into 8ohm, how can it do that at +/-47?? :roll: Am I missing a point? Is it due to single-endedness?
It runs hot, but just about everything in my rack is class A, so the AC just runs all the time, summer or winter...All in all a great amp ... I just think you need 75 volt minimum and prefer to get up towards 100. BUT ... in Class A mode that would make for lots of heat in the equipment room. Probably too much
These amps really are about doing as little as possible while keeping the signal as accurate as possible, and my ears tell me he struck a nice balance. I've not heard a better sounding amplifier...
