There are no "problems," per se. There are defined limitations of the design. The first is that it uses MultEQ, not MultEQ XT. The second is that the DSP engine of the AV8003 cannot do Audyssey processing and decoding of HD codecs at the same time. The solution to this is to decode them in the player and send PCM to the Marantz. Sound quality, per se, is unaffected and, according to many, is excellent. Your move.
