So how can a great system solve less than great recordings


It seems no matter how good a system is, the quality of recording quality takes priority.

Formsome reason nobody talks about challenges of making older recordings sound better.  Classics from 70s and 80s are amazing tunes, but even remastered editions still cant make sound qualiity shortcomings all better.  Profoundly sad.  Some older stuff sounds quite good but lots of stuff is disturbing.

I stumbled upon some interesting info recently, related to record producer Rick Rubin, criticized for recording (producing?) techniques. See "Production Style" near the end of his wikipedia page. What a shame to waste a good recording opportunity on poor-outcome recording/production methods.
OP, you mentioned "album" but didn't clearly state whether your poorer recordings are on vinyl, CD, or streaming (unless I missed it).

I believe there are threads here related to finding better versions when streaming, as a means of avoiding the poorer recordings/productions/CD transfers.
You can't make a silk purse out of a sow's ear. I too ask this question. If the recording quality sucks, 6 figure equipment won't improve it I'm afraid. 
i think what great systems can do is to unravel and reveal the musical truth of more complicated dynamically challenging recordings that seem opaque, or harsh, or confused on lesser systems. this can be with any media type.

but great systems cannot overcome poor recording processes or poorly mastered media.....or poor performance.

garbage in = garbage out.

but how can you know when it's the fault of the media, recording, or performance.....or your system? that only comes from lots of investment of time and effort. not a quick and easy thing.

i have a number of recordings that were referred to me (as special and worth investigating) but i could not understand or relate to them until my system evolved to the point where i could hear what was happening musically. i suspect it was also me that had to evolve to appreciate the musical intent.

so viewing any music as less than great might be more about us as listeners, than the recording. but system development has it’s role too.

the best systems can reliably separate the wheat from the chaff. which is a main reason for improving your system, for more music to matter to you. widen your reach and depth of your experience.
