I currently run a BeoCenter 9300 with a pair of Penta 1 (SL to PL adaptors) and have an odd issue. On one penta the display, amp, woofer, and tweeter seems to work just great just the midrange seems not to be working (did test sweeps to isolate midrange output to no avail). On the other the display works...

I am considering buying a Beocenter 9000, and I have two questions. First, will my Beogram 4002 (with built-in quad decoder) plug into it? I realize it won't have remote capability, but will the 4-channel circuitry interfere? Would I simply leave it set on 2-channel? Second, I see the Beocenter 9000...
