Not sure if RP is the a good reference or not as I don't use that service, but there are a couple things to consider.
- If you don't know the CAT # of the specific album, well that is a major prob. That is also a big downside to streaming - you have no idea (many times) of the provenance as well as they can remove/change said album version at any given point and you'll never know (generally speaking)
- The recording/mixing/mastering means everything (provenance) and if one doesn't know that then all bets are off
- Some recordings most def sound better than others (I would hope so)? However, as has been pointed out, the room/acoustics are paramount to SQ along with proper setup. Those two items are an absolute MUST before anything else.
