Good plan! I've had my AV20 for around 3 months now and it's running flawlessly here. I'm still working on Audyssey and a couple of it's variations right now.I’m planning on selling my XMC2 and getting the AV20 so I can get DLBC and ART - this was what I was hoping to get with Emotiva when they first integrated with Dirac.
When I get finished with that I will download the trial version of ART to test before committing $1k to it's purchase..
