separate amp or upgrade HT receiver?
I have a pretty inexpensive budget system right now... I have a HK AVR 235 (surround sound receiver) paired with KEF Q5 speakers.
Many reviews say that the NAD T7xx and ROTEL RSX HT receivers are far more musical, more dynamic than the typical HT receiver.
The HK AVR 235 has preamp outputs for all the channels.
If I wanted to improve the musicality of my audio system, should I just replace my HK with a NAD T743/T753, ROTEL RSX-1057 etc, or would I be better off keeping my HK receiver, and, say, get a separate stereo amplifier like a NAD C272?
If I am better off buying a separate power amp, are there any advantages at all to replacing the ht receiver?
Thanks so much.
