I am running a pair of Rotel RB981 power amps bridged for mono. From what I read these were Recommended Class C for their time. Can anyone tell me what the pros and cons of switching over to a higher rated single stereo amp such as Classe 15, Anthem MCA-20 or a PS Audio HCA-2 would be? Any advantage to keeping it the way it is besides the obvious power per channel?
Thanks
