onkyo 805 vs 806


i heard there are a few differences, such as codecs being burr browns vs 806's different cirrus i believe. I was going to do a pre/ with an amp but an audiogoner has steered me this way? Which unit is better both can be had used? Which comes with better features?

Blindjim, yes, I use the Audyssey for the EQ, but usually set my volume levels with an SPL meter after I run the Audyssey. I have found that Audyssey gets the levels pretty close, but typically need a bit of tweaking, especially the sub. Otherwise, the Audyssey works great, IMO. I have not used separate amps with the 805.
There are four for sale on ebay right now:

Go for it!
Cruz123,

My post said the 805 does not have AUDYSSEY DYNAMIC EQ and indeed it does not. This is a brand new feature of Audyssey MultEQ that is on the 806 but not the 805.
i saw these. i am bidding on the one you originally sent me DL, thanks for all your help. So is the audyssey on the 805 not that good is what im hearing???
Athens, IMO, the Audyssey EQ works great on the 805.

Dlcockrum, thanks for the distinction. I just didn't want the OP to get the impression that Audyssey was not included at all in the 805.
