Listen for a week or two then switch back to what you had before. That can sometimes be more dramatic. Another thing, which was one of my first experiences with higher-quality hi-fi than what I was used to is that the better clarity isn't a dramatic experience. If anything it can be an anti-climax. It's not the same as going from cheap IEMs to ones with great, thumping bass, which is very noticeable. Some people buy different or better headphones or gear for the greater thump in the bass, others (like myself) for clarity (and maybe a bit of an extra kick in the bass too sometimes). Better gear will not have any harshness that makes listening for long periods irritating, which some cheaper gear has. Good gear makes you stop thinking about the gear and notice the music.
That is an excellent description that my own experience mirrors. Greater clarity, lower distortion, reduced or eliminated listening fatigue. Then listen to lesser gear and the loss of those attributes is more dramatic. I have been spending much more time recreationally listening to my library since putting together the WA7 and T90 combination. Alternate for me is WA3+ with 2399/5998 tube and either T90 or HD800. So much music, so little time. I record and edit voice as part of my day job and spend a lot of time working using Benchmark DAC1, Violectric V800 and V200 with various headphones. Very sensitized to listening fatigue. Until the last couple of years and the dramatic improvement in headphones and amps, I could not listen recreationally after ten hours of audio work day.
