I Am considering the purchase of a Marantz AV7702 processor which has Audyssey XT-32 and Dolby ATMOS. I like all the features of the AV7702 and ATMOS is fascinating, but my experience was so bad with Audyssey XT I am concerned that even the upgraded XT-32 might not work well for me. However, Dirac looks like a room EQ system with great promise. If I could somehow get a Dirac equipped Mini DSP to work with the AV7702, that is without degrading the basic sound of the unit, and maybe even working with ATMOS, I would be very pleased. Will any of the Dirac Mini DSP units with Dirac work with multichannel systems? I would greatly appreciate any advice any of you can offer.
