Thanks for the perspective but I'm not convinced, I personally find the Q&A responses more intellectually engaging. Also perhaps let's not compare (strictly by instruments) the output of the very first MQA hardware implementations. Tidal has MQA, fine, we can still go and buy hi-res for $30 per album. For me, the important keyword is "splines". Think of taps, but better? So and Pro iDSD doesn't support MQA as of yet?
