I get your post and appreciate where you are coming from.
Myself and quite a few others on the forum have been, to one extent or another, involved in and have had a love for audio and good music for many years and like you, have enjoyed an evolution over the years that has enhanced our enjoyment of this fine hobby or relaxing or involving get away, as it might be.
Over the years (starting back in the late 70s early 80s) I progressed in equipment (some a step up, some not) experimented with tweaks (some made a noticeable improvement, some not) and room treatments. Since I have hundreds of choice vinyl LPs and many hundreds of CDs, and I'm still healthy enough to get up and turn over a LP or change a disc - I'm not to excited about a costly move to streaming, but that's a personal, not particularly a sonic preference.
Erik's take, I believe, is that, even if these upgrades, tweaks, etc. do add all that extra detail and resolution, that doesn't necessarily mean it will be more musical.
My point was in line with Erik in that I don't believe that every supposed leap up in detail and resolution necessarily means better sound. More specifically my point is that when one brags about their incredible best of the best system and then later that just replaced stock fuses, power cables, what ever, with XXX and brought my incredible system to a whole new level and a few months later say - just replaced my xxx fuse with xxyx fuse and couldn't believe - just brought my best of the best of the best system to a whole new level of the best and it goes on. At some point I stop believing the hype.......Jim
