help with Classe ca3200 vs Parasound A51

Hi: I need some advice here. I have a Classe CA3200 driving a pair of Paradigm S8s and C5, and a couple of cheap 2-channel amps (Classe and Adcom) to drive the Paradigm ADP3 surround and ADP690 back. Processor is Cary Audio Cinema 11a. My only complaint is that the female voice (whether listening to music or movie dialogue) sounds a little raspy/hoarse. I tried the CA3200 in my music room with better preamp and speakers and it sounded the same. The parasound JC1 in my music room does not have that problem. I am wondering whether the Parasound A51 would be a good choice for my home theater system or its a downgrade. Any suggestions are most appreciated. Thanks. Ron
