Having owned this unit for a couple of months now, I'd agree with what aolmrd1241 said. Re. mqa discs, which the D-10X obviously can natively play, I've bought and listened to two of them- one a recording of works by shostakovich, lutoslawski, and schnittke; and the other being Zenyatta Mondatta by the Police. I found neither one to be superior to a well-mastered cd, and both sonically inferior to good SACDs of these kinds of material. The classical disc, while having well-played pieces by composers whose works I love, had a strident tonal balance- overly hot treble- which I have generally not noticed in other cds played in the Luxman, which has a very fine tonal balance.
Given MQA's highly proprietary nature, plus its limited and non-unique library of releases, I feel no need to follow up on more discs of that type. And to be clear, I'm a big fan of the SACD and DVD-A formats, so the niche quality alone doesn't bother me, but all this for expensive plain cds plus the early MQA attempts to bend the digital market to its own agenda are no good at all.
