Thanks Dave,
You know I can't argue with that logic and really should have come to that conclusion. Of course the dynamics of the amp get thrashed by big resistors and I'll bet the phase get's slightly twisted as well. 

Darn, I was hoping to be able to do something clever to attenuate the output and control it all with my SX's 

I'll have a good look at the link you suggested. My Dad will have a fit though. He's a tube guy. 6550's and big Acrosound TO-330's. I just picked up a couple of vintage Dynaco A430's for him. He's going to build a pair of Ultra Linears. He's not going to be impressed with my solid state amps at all     :nono: 

....But, if I can build a 10 channel 50w per channel amp for about $200, I'm in!   

Cheers,
Andrew
