Sberry,
I see your objective here. I live on Streaming! Local Files, Paid Subscription Services, DAB, etc.
For your Local Files, you can simply add the RME Bit Test Files to your music server, and Fire at Will I do this routinely after any system tweaks as a means of my own, in-house QA to ensure I haven't borked the data path in some manner
I think we potentially get into difficulties with Streaming Services like Tidal, Qobuz, et al. Even their innocent application of Volume Normalization would cause a Bit Test Fail.
*although I'm not sure if Qobuz is normalizing anything, as Levels vary as widely as my own un-boogered Music collection. Qobuz is now my preferred Paid service. They sound great, and I don't have to buy anything else.
I suspect Amazon HD isn't so Lily-White, as in comparison to the CD rip? Amazon is loud!!! (That, and their API is so locked up it's not useable by any device that isn't Amazon-enabled. No Thank You!
*Louder is always perceived as better to the listener. I'm not falling into the "HD" trap.
I like the your idea nonetheless. It'd be fun to try! Live & Learn.
Fwiw: a friend offered to stream a bit test file on his station's DAB to test this very thing...but again, the Bit Test files would never succeed after all the EQ, Compression, Level tweaks, etc applied by any Broadcaster.
So...
My $0.02. (Now worth approx $0.0175)
Stream on Friend!
