Too Much Power

@gnoworyta the preamp is also PS Audio, the model is the BHK Signature

with speakers rated at 900 watts and have little concern about over powering or damaging them

You have a home audio speaker that can take 900 watts?

I bought these to replace a Peachtree 220. They are light weight, dead quiet and sound great. I got an offer from PS Audio to trade them for a BHK Stereo 250 so I accepted and shipped the monoblocks back. The 250 is a lot noisier but is creamy and wonderful.  Too much power is better than not enough, and you would have to turn up the volume almost all the way to get close to the maximum output. The 250 watts is more than I need because my speakers have powered subwoofers and the input impedance is over 20 ohms at low frequencies. 

@russ69 I know 900 watts sounds like a stretch and I can neither confirm or deny, though that is what's listed on the product literature

@stevewharton  Wow. I had not seen that before. That is quite a claim. Not sure I'd want to test that claim. Thanx for the reply.
