Yep, the rear port vs the front port is also very important. In my room, the speakers will be near the wall so C1 is at a slight disadvantage for me. Also my cables are bi-wire..the C1 only takes single pair of wires, which is another downside. This doesn't necessarily mean I have given up on the C1, so I'll give it a audition when I'm in the bay area. But at this rate, the C1 would almost have to be at another level than the 805D. Thanks everyone for your replies. It seems 90% of people have chimed in about the C1, so I'm hoping for more 805D highlights. Also the 805D seems lacking in bass??? I had the impression that its very tuneful, tight, and well timed..of course its not at the same level of the C1 in terms of fullness, but its not enough to say the C1 totally dominates in this area vs the 805D, would anyone agree?
