Yes, I am not currently running ARC and am letting XT32 do all the EQ/RC. I am able to get a nice flat response with just Audyssey and careful placement but, I am always looking to refine.
Yes, I have been experimenting with different cut off points and have seen better results with limiting Audyssey to the lower frequencies.
Already on that one and it is a planned upgrade down the road when funds permit. I'm thinking of getting a 5 channel and just letting the Denon handle the heights(or at least a three channel minimum for the front stage). Not sure what amp yet though but, something that definitely measures better then my Denon. I'd like a Parasound A51 but, don't know if I can stomach the price tag.
Really? You might be the first person I have ever heard critical of the PSA subs. They get pretty amazing reviews and their measured performance is crazy compared to brands like SVS(PSA is owned by one of the SVS founders I am sure you know). JTR gets amazing reviews too but, the wait for those is often extremely long. You don't think the TV2112 would still have crazy low bass with its 21" drivers? I am aware PSA highlights mid bass but, still. I talked to one guy that had 2 x PB16 Ultra and he said these have almost 3 times the output and completely put them to shame in all aspects.
I'll have to check that out. I thought about getting a MiniDSP 2x4 HD a while back but, I was able to get my response pretty flat so I kyboshed the idea to put the funds elsewhere. Here is my response a while back. I still have work to do in the higher bass but, from 20-100hz I don't think I could get it much better. This is in an absolutely horrible room acoustically too and I will be buying a new house soon with a better room to work with...
