Yes the recordings has to contain actual ultrasonic content otherwise MQA is pointless even for is intended purpose .
And not any haphazard ultrasonic content the producer has to know what he is doing . Did not both Theta and Pioneer ( legato link ) both had some failed aproach to guess/generate the overtones . the failure is that the information is lost forever can not be recreated .... Sadly I thinks it's very tempting to do this again to generate content . The recording process do use 24/192 these days to avoid brick wall filters etc and further use floating point data in subsequent software that mixes and produces the stuff . The benefits are clear to all of us but actually it does not necessarily needs to be distributed in that format to the end user . Like most digital processing the practice to use very high Rez source material makes good sense just like in Photoshop ( I did buttons for my remote control app in more than 1000*1000 res even if they are shrunken down to 72px in iRule , but all plugins and effects etc worked so much better ) . But the subsequent distribution to consumers ? We have very good resamplers and dither algorithms these days . Anecdote I have even used bad algorithms and rather sloppy conversion processes for my own tests , and I could still not detect any difference that's how good today's stuff is . If you want to "test" hirez in some ABX fashion use SoX or something and resample some of the better hirez recordings you have . Do not compare to the cd release or cd layer that came with the disc ;) they obviously sound "different" ( because the obvious fact that they are not the same master ) Personally looking at most distortions curves on power amps they peak in the HF and also typical HF resonance peaks in tweeters ( transformer resonances in tube amps anyone ? ) I only see a possible way for intermodulation distortion this would sound different ofcourse ..... -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
