Sound Quality of red book CDs vs.streaming

In the chain below, Tidal 16/44 sounds better than Redbook, MQA sounds much better (afraid I might become an MQA junkie), and I can't hear a difference between FLAC and Tidal streaming.  I have to go back and try WAV.  My disc spinning has nearly stopped as a result.

Also intend to try better ethernet cable, based on what I've read here on the 'Gon, currently have cheapo, want to try Supra.  For what it's worth, I think PS Audio believes transmission via ethernet to be superior to toslink, upc, can't remember why tho.  

Oppo 105D via AQ toslink or Tidal/Roon from modem via ethernet -> PS Audio Perfect Wave DAC with Bridge II.

I find cd is better than hard drive AND streaming through my MSB Transport and DAC. 

If using Roon or Android Hi-Fi Cast (most any app/software except Google’s own), the jitter in the ChromeCast Audio is better than -275dBFS (better than 45Bit). @audioengr’s re-clocker will actually introduce more jitter in this case. It’s only if you Cast with YouTube or your Chrome Browser will the re-clocker actually reduce the jitter; however, any good DAC will be audibly the same for cheaper, $700 for a re-clocker is silly when a $250 SMSL SU-8  DAC has jitter below -120dBFS, what is considered out hearing range (some say 140dB), and accounting for room noise, it’s more than enough.

You don’t give specs as to what dBFS or psec your product is; you’ve stated 7psec before, so I’ll assume that, the ChromeCast Audio has less than 4psec (better than -275dBFS / 45Bit). If your product is better, I’ll retract my statement. Again though, even if your re-clocker was 0psec, the differences are not even close to audible, so spending $700 one one would be waste of money in this instance.

Even the $100 Khadas Tone board DAC has a J-test result of -135dBFS, which allows for more dynamic range than we can hear in a room (say 140dB max and a room noise floor of 30dB, so 110dB; and that 140dB is generous, most music is mastered to 105dB, with some orchestral/classical getting to 120dB).

A ChromeCast Audio hooked up to a “cheap” Topping D50 DAC, using normal cables, produced a J-test of better than -130dBFS, also better than our hearing in a room.
