Bryston or McIntosh

It is impossible to provide any comment to such an overly broad question.

It it depends entirely on the synergy (or lack of it) with the rest of the system (ignoring the unique wild card characteristics introduced by the warts and limitations in the listening arena etc.)

If you like listening to music, go McIntosh.
If you want more detail, go Bryston.
I have a 4B3 and Mc 452.

I'm agree with you 100%
