Hmmm. A few quotes from VirusKiller's post:

So the MQA encoding process removes parts of the signal in a manner that
will not be audible to a human listener. Exactly how is this something
new? "Encoded for human hearing" is *precisely* what traditional lossy
encoders (MP3, Vorbis, AAC, etc) have always done - some better than
others. Meridian might claim that their encoding is more transparent
than others, but to say it isn't "lossy" is basically a lie. And given
the fact that modern high bitrate MP3/Vorbis/AAC/etc is indeed
transparent in all but the most extreme and contrived situations, is
there actually any need to invent another format?

I appreciate that when played back through a suitable MQA decoder, the
removed parts are intended to be restored, meaning it is no longer
lossy. But the idea is that MQA encoded stuff will be playable on legacy
equipment without a decoder, in which case it *is* lossy. Sounds a bit
like a more extreme form of HDCD to me.

No Sh*t, Sherlock. The music industry will welcome with open arms *any*
technology which promises to allow them to sell their back catalogue yet
again.

The most recent recording that could ever possibly have been made by
Louis Armstrong would date from 1971 (the year he died). This predates
Dolby SR by 15 years. Do you honestly think there was any recording
technology available in 1971 that could have captured the ~100kHz
bandwidth which Bob Stuart seems to think is required to cope with the
human ear's ability to distinguish events down to the 10 microsecond
interval? (Note: this is the same Bob Stuart who once stated that 19
bits and 60kHz sampling rate were sufficient - presumably back in the
days when that's the maximum that Meridian could envisage delivering).
Or that has an S/N ratio even remotely approaching the 96dB that 16 bit
PCM is capable of? No, didn't think so. In which case, perhaps the
wonderful sound that VirusKiller heard might have been more to do with
the mastering, playback equipment or room, and *nothing* to do with it
having been encoded by the wonderful MQA system?

MQA is another solution in search of a problem, and gullible audiofools
are going to lap it up just because it's Meridian. If Microsoft or Sony
had come up with this, it would have been laughed at for the smoke &
mirrors it is.
