It occurred to me that something other than MQA was utilized to make the MQA sample sound so much better on this custom made track.
My mind says no to MQA for many reasons including the fact that it is lossy and claims to be master quality authenticated when it seems to me that it would be difficult if not impossible to recreate and reverse engineer the attributes of an A/D converter and entire recording chain when the converter and chain are, in many cases unknown and/or no longer exist. My ears said yes on that one occasion. I need to hear many more track comparisons before I buy in to the MQA format which just happens to be another opportunity for record companies who adopt it as a new standard to sell us the same music once again.
