My C356BEE has powered very nicely, my Epos Epic 2 which are 90dB 4ohm speakers, superb sounding combo!! I now have Rega RX5 speakers and still the NAD does not falter. Nice big sound, clean and with tremendous low end....The C375BEE is interesting only for the 150wpc, the other options are not needed, but for a good price never know.
I also use the Audioquest preamp jumpers, the difference is noticeable for sure.....cheap upgrade.
