Hi all. I have an old Harman Kardon AVI250 Pro-Logic THX amp, which has 5.1 inputs. In your opinion, would it be a good idea to get a decent mid-range receiver to use as a processor in conjunction with the HK power-amps? If yes, what receiver would you suggest? How would such a setup compare to higher-range receivers (specifically a Denon AVC1AD)? Used for: 80% HC / 20% music Speakers: Mission 774, Gale center, Boston VRS-Micro rears. DVD players: Pioneer DV626D; Denon 3800 (which I might be selling to upgrade my tv). TIA.
