Given the amount of time that's passed, it's interesting that so few hardware partners seem to have come out with MQA compliant equipment. If you do a search here on Audiogon for "MQA", you get the same 3-6 listings (from the same seller) for the Mytek Brooklyn.
Besides that, there's the Meridian Explorer and a couple of portable players plus the Mytek Manhattan II. Anything else?
