Hello everyone, I may be kicking a dead horse here but can anyone tell me the difference between the M5150 and the M5160? Both rated at 150 wpc both delta design amps....

I just got a 5150 and would like a matching amp to bi-amp my Polks....but I can aquire a 5160....so good match..bad match...?

I will be temporarily employing the P 3150 preamp fpr this rig.....hopefully making the jump to a p-306 soon.

Any thoughts are welcome..and thank you!
