Hi

I'm hoping to slightly upgrade my (old/basic/cheap) home theater system and also add 2ch audio-only components to the same system, all driven by one receiver and sared speakers. I'm not sure if this is sensible/do-able, or if so what components might be suitable so looking for advice.

Existing Home Theater audio:
- denon receiver/5.1 speaker combo
- samsung blu-ray player (1), oppo dvd player (2), cable box (3)

Stereo / Home Theater audio requirements:
- turntable (4) (Budget: $200), cd-player (5) (Budget: $200), wireless / streaming audio from PC / home network (6)
- receiver, into which i can feed audio signal for all units mentioned above - 1&2 via coax, 3 via optical, and 4-6 via most appropriate means. Budget: $500-700
- upgrade front L&R channels to optimize 2-ch audio: Budget: $300-700


Many thanks!
