@johnlnyc I'll second that, thank you!
I would also add that our hearing perception does get in the way from time to time and, to keep music sounding fresh, we need new sounds, presented in new ways, to challenge us. This can be new music programme, an audio sabbatical, some changes to our system set up, or a multitude of other things, including personal wellbeing.
As an example, I sometimes by-pass my pre amp and plug the XLR output of my DAC directly into my power amp. Providing DAC's have a very good volume control, this works well and only takes a couple of minutes to execute. The sound then becomes a little more "clinical" with slightly more dynamics, but the trade-off is a small loss in musical engagement. However, the "new" sound gets my attention. After a couple of days (maybe 4-6 hours of listening time) switching back to including the pre amp in my system, immediately delivers a more entertaining sound and my hearing perception is refreshed again. Even wetting my industrial scale grounding mat does the trick, sometimes. It is an advantage to all music lovers, to understand the perception of hearing and to consider that maybe our system is not a fault, but we may have become a little complacent with the sound and presentation it is producing.
Only this morning did I have a wonderfully emotional listening experience, playing some music that I had not heard for maybe a year of more. I was astonished by how engaging and entertaining that 2 hour listening session was and, how different music production styles affected my enjoyment of the music to some degree.
Kind regards,
