Are you a recording/mastering engineer, are you saying they use a different master for CD v cassette?

Some cassettes sound way better than the CD, assume they use the same master?

Oops, some require 24bit: https://theproaudiofiles.com/audio-mastering-format-and-delivery-guide-2014/

Here is a thread on Gearslutz by recording engineer who says you can't create a RBCD from a 24bit master without ruining SQ: https://www.gearslutz.com/board/mastering-forum/151620-what-best-16-bit-d-converter.html

Sure, curious why Barry records to aiff when most distributors require 24bit wav files?

I used DBpoweramp, what would you recommend?

I see Barry records to aiff like you do Paul. Have you tried wav? Thing is, I tried converting your Chopin needle drop from aiff to wav and couldn't do so without ruining the SQ.

Couldn't open the file, do you mind reposting? Cheers

So you couldn't tell the difference?

Lol, thanks for the file and graphs though, very interesting for those that can hear a clear difference.

It tells me something I already knew: measurements don't mean squat. Maybe as this is OT the comparison should be posted in a new thread.

Here is your 24/192 (aiff) recording: https://audiophilestyle.com/applications/core/interface/file/attachment.php?id=56129 And here is the same, down sampled to 16/44.1 (wav): https://send.firefox.com/download/1af2ef1d48ecda79/#792ya3sGL2JKAH0pFhJYKQ The downsample sounds bad doesn't it, why?

No Paul, we are referring to your original 24/192 aiff v esitudes 16/44 downsample of the same. Frank confused matters. Your recording sounds great, the other sounds off.

I'm comparing your 16/44 wav downsample to Pauls 24/192 aiff, did you make a mistake when downsampling?

Just tried comparing in Foobar and the 24/192 is clearly better than the 16/44.1 its not even close. Maybe the down sampled file would sound better if the original was recorded at 24/176.4? Very interesting, Thank you @Paul R
