So a receiver + stereo amp would not work. I am pretty sure that the power AND the gain need to be the same for all channels powering the new speakers


i'd be willing to bet that the amp for the rear section doesn't need to be as powerful as the front section. i bet only the gain needs to be identical. lets face it the rear only has 2 tweeters and 2 mid-woofers. the front has all of that plus 3 (sub) woofers.

time will tell


This was my e-mail to which the response above i received.

However, could i use the 250a for 2 of the channels, and buy a KAV 150 (150W @8ohm and 300W @ 4ohm) for the other 2 channels, i am pretty sure that the 150 and 250 have the same gain, i will have to call krell to verify, or should i just get a second 250a?

I would guess there is a reason why you need matching amplification. Also, Ian specifically said "exactly the same"... I am going to do what Ian said to do, since he and Andrew designed the things.
