Mike, the 4311 mentioned by AVJ is the one that meets your specifications(i.e., simultaneous 11 channel operation including back surrounds, front heights, front wides, and two sub outs with independent calibration)and is more or less your 3808 three generations later. Also note that it has the top Audyssey version, MultEQ XT32.
