OK, one of the FPB750MCX amps has failed and was drawing in excess of 15 amps from the wall at idle so I boxed them up for repair. I sold all my extra amps so now for this system the only extra amp I have lying around was a S300i. I set the little amp up in theater pass through mode for the mean time, and set up the 801N's again, it dosn't sound too bad when you bypass the preamp, the preamp is the real weakness of the S300i. Well ok, listened to a little led Zeppelin then some Michael Jackson from the this is it blue ray, turned my trusty Krell preamp up to about 50%, after about 4-5 minutes the amp went into thermal overload which it stated nicely on the display. Once it cooled off it shut itself off I turned it back on and it played fine. I could see from the P-1200 it's hooked to it was drawing a lot of power for a little amp. Can't wait to get my babies back.
On another note I spoke with Dan Daugustino a fare amount when he was here at the show in SF recently, he said the Krell amps should be running at 220 volts and they will sound a lot better. Come to find out they are all designed originally for that voltage, the MRA amps were designed to only run at 220. So looks like I have to save some pennies and do some more work on the house here...
Have fun guys,
