The best part about MQA bankruptcy..

@onhwy61 Sorry about that.  I now see you were the one that used the 'unfolding' line.  Very clever.

@audioisnobiggie SACD is not dead, it prospers as even higher bitrate dsd files.  They're up to dsd256, up from the original 64, so far.  There's probably higher already, my dac can do 512.

yes but there is a huge disadvantage to dsd 512 the file sizes are very large and still to this day hard drives are not big enough to fit many albums at dsd 512 size even dsd 256 will also take up way too much space with not that much of a difference in sound from 44.1 kHz and 16 bits, it’s quite sad how much we get ripped off and never taught the truth 

MQA is very good from my experience with a MSB DAC.

I have a dCS Bartok (now being upgraded to Apex) and I have the same experience when playing MQA files on Tidal. These DACs, and perhaps some other high end DACs, have been able to deliver excellent SQ from MQA. If you heard MQA over these DACs you might change your mind about its quality.

Erik, love the play on words you used on ’unfolding’.

True credit here goes to @onhwy61 , I just borrowed his idea.

These DACs, and perhaps some other high end DACs, have been able to deliver excellent SQ from MQA. If you heard MQA over these DACs you might change your mind about its quality.

Isn't 95% of the perceived sound quality a result of convincing engineering in the recording - meaning mics, placement room, preamps, conversion and convincing artistic choices in mastering?
The medium or resolution itself is IMO only a limiting factor if you go below cd quality. A better recording "on cd" sounds better than a lesser recording on high-rez.

Regarding MQA: Its point is not compression per se (and/or the unfolding of your pocket) but the integrated view on the whole chain of AD anti-aliasing and DA oversampling filters and the touted control of an optimal resulting impulse response.

The first problem is the black box, the secrecy, intransparency and lack of control around the process.

A second possible problem is the promised phase- & impulse-perfect stitching together of a 22kHz lowpass signal with a 22kHz high pass signal.

I'd like to see also "neutral" comparisons of impulse measurements AD/DA of a complete recording chain, including measurements of dynamically more complex signals. Usually one only sees "filter ringing" provoked by incorrect artificial digital signals on DA. 

The somehow speculative audibility of filter ringing will disappear the higher the sampling rate.

I still find the idea of MQA intriguing and promising - except the ripp-off aspect...
