I have been usin a PS Audio P5 for a couple of months and it has been good.
I had it in Sinewave mode as I run a turntable and think I read that it could effect the speed if in Multiwave mode. Garrard 401 and a Pioneer PLX-1000.
I switched over to Multiwave mode and notice the THD out is always a lot higher. In sine mode it is always 0.1 but in Multi mode right now it is around 0.5. When my THD in goes up so does the the THD out but only in Mulitwave mode.
Is this normal? Sounds good by the way.
I was running .39 firmware and just went back to Multiwave upgrade .38 and it seems to stay around the same.
