This is not special technology just more hand waving from the promoters of MQA...of course they claim their filter is “special” and an improvement...
Well, they have spent a lot of money and time saying the opposite.
I have owned several DACs that had numerous digital "filter" settings. Nothing I have ever come across or heard does what MQA does. No matter the DAC filter setting.
@shadorne...do you have an MQA DAC? Or you just saying the "master" tracks sound better than their regular CD tracks on Tidal, (which I also agree do sound better, but even better if MQA decoded).
After many, many hours of listening, IMHO, Bob and his team did what they claim. Sounds better to me.
I guess we will just agree to disagree...
