@kota1 … once you reach a point… because changes might actually degrade the enjoyment.”
Yes, for the last couple years I have been methodically adjusting and tweaking positioning, wires, and room acoustics and zeroing in on, what for me is the best sound. The improvement has been unreal. While I have done the same sequence and tweaking on previous systems, in the past changes were frequently punctuated by business trips and vacations. Being retired the cause and effects are much more easily detected in continuous long listening sessions.
Probably the greatest thing for me over the last few years was bringing my streaming up to the level of my vinyl system. My content went basically to infinity as I have have more time to listen… so for any group I used to like I can explore all the most of the albums I had not bought. Also, when I feel like it I can pull out an album and enjoy the tradition I performed since a little kid.
