blu-ray sony bdp-s370

given my choice will be keep sr6006 as processor only & connect pre out to power amp.

7008 has more spkr channel, 4k support & audyssey xt32 but not essential upgrade if aiming sound quality

Don't see the point , as the sound won't change much but maybe a little bit more power that is all.

estimate 800usd.

have u removed the link bar behind spkr and do passive biamp?
greatly improved on mine set, that has similarity to yours (mordaunt short declaration & sr5006)

alrite this is the binding post of front pair.
[attachmentid=5148934]
notice the HF and LF has copper link/ jumper removed.
i make another run of cable to sr5006 amp assign port (zone2, surround back)
have to very careful that red and black must follow, just split the HF to front spkr A port while LF to amp assign port.

from avr menu, go system, spkr setting, amp assign to spkr-c which is the bi amp mode.

after that make low volume test to ensure they are correctly connected. may need to calibrate audyssey since it cannot enable yet.

Yes I am sure is a good upgrade. I think the price is about 4.5k

tq sifu.....ok,i go buy speaker cable first....tq sifu

if i upgrade av to sr7008,...sound quality improve or same?
