^ I concur: the display is showing the incoming signal sampling rate, not how the processing is being done internally. Engaging (I suspect)
any digital signal processing, including how it extracts a signal from analog sources to send to the sub for bass management, is done at 48kHz. According to Chris Kyriakakis, co-founder of Audyssey, this is a decision made by the AVR/Prepro manufacturers to save money on processing chips and not an inherent limitation of Audyssey itself.
There is no good evidence sampling rates higher than this are necessary anyways, because there is no good evidence humans can hear much above 20kHz, at best, and 48kHz can even record up to 24kHz sound, if need be. That is, 48kHz sampling is already better than it needs to be. Hi-Re$ is a marketing scam in my opinion and even Mark Waldrep of AIX records is starting to realize this himself.

There are really only three things one needs to know about MQA, besides the fact that it's a money grabbing scheme according to the co-inventor of SACD and DSD/Sonoma,
Andreas Koch:
A. It's lossy.
B. They specifically tried to keep that fact from us in their initial advertising. Example:
Only once other technical people exposed the truth that it's most certainly a lossy process did they then admit it and pull their misleading ads. [Their use of these misleading ads speaks volumes as to the MQA company's integrity and trustworthiness in my book.]
C. Since it is lossy,
any audible sound difference whatsoever is dubious because we'll never know for sure if what we are hearing is actually just the artifacts of their lossy process.
Cleverly when this was all exposed they argued, paraphrased: "Well, just because our process is technically 'lossy' and degrades the sound as compared to the content on the original master tape itself,
that's not what's important. See, our magical process brings you closer to the original sound, in the air,
before it even got recorded!" Riiiiiiiiiight. See why that's clever? It is impossible to prove them wrong because the goal sound is indeterminable.
