The central issue as I see it in this thread is whether or not music can be "distorted" to achieve a sound which sounds more realistic to the average listener. Many here are arguing that transparency alone is not the future or the holy grail and many argue that it is. My point is that in 150 years, I find it highly likely that technology will allow presently recorded music to sound much more realistic (from a live perspective) due to manipulation (distortion) of the recording signal. This process is already underway actually and I would guess that in 150 years, the technology will bring us much close to realistic sounding recordings. Again, not an argument, just a guess.
What you're talking about is a highly advanced form of DSP, and in particular a highly advanced form of something like upmixing a stereo recording to multi-channel Dolby Atmos with various spatial enhancements to create a more physically and sensorily immersive experience.
That's cool, and I have no doubt you are correct that something like that will be developed in 150 years, probably more advanced - and in some way very different - than any of us can imagine today.
But for such methods to work properly, the equipment that reproduces and processes the recordings in that way will need to be as audibly transparent as possible - it will need to reproduce the sounds, however processed, with as little noise and undesired distortion as possible, adding only changes to the signal that are part of the intentional design of the algorithms of the DSP.
The fact that any change in the original signal can be characterized under the heading of "distortion" does not mean that the kind of intentional, consistent, evidence-backed signal processing you are talking about is actually the same thing as, for example, elevated noise, poor rejection of out-of-band signals, nonlinear frequency response, or high intermodulation distortion. And therefore your claim - or at least strong implication - that the existence of DSP means ASR's dedication to transparency is narrow-minded or misguided, is an illogical and unpersuasive claim.
