Kana: My comments are not only based on the technical measurements that John Curl obtained when testing this unit, but the suitability of this product for Rick's specific intended use.
From my past experience with the Perreaux 2150's, these amps typically clip in excess of 250 wpc @ 8 ohms and 400+ wpc @ 4 ohms. The 3150 is a far beefier amp with much greater bottom end authority, as Rick will confirm. While i can't explain the specific problems that he's having, my guess is that the Carver Pro might not solve the problem and would probably be a step backwards in terms of bass output and control.
The fact that the ZR 1600 was breaking up / oscillating at less than 200 wpc @ 8 ohms ( John measured 180 wpc into a dummy load ) would mean that it would probably perform even worse with a more reactive, far lower impedance load. Comparing that to the "real" 500+ wpc that the 3150 is capable of into 4 ohm loads or even the 400 wpc that the 2150 was offering should demonstrate why i have the thoughts that i do.
As a side note judging by what Rick and i discussed on the phone, i don't think that he's unhappy with the performance of the 3150. From what i gathered, i think that his main problem is the hum and other "odd" noise being generated with it in the system. If he could solve this problem, i think that he would prefer to run what he already has. I could be wrong, but that's what i was led to believe. Sean
