In total agreement about the room, even the slightest correction with treatments makes a major improvement as does figuring out how your speakers respond to placement, toe in, etc..
I personally found by switching from bookshelves, (Triangle Comete’ EZ’s), to dipoles (Maggi .7’s), I was able to enjoy music again. I went back to listening rather than hearing what the speakers were and were not doing.
As we age and after years of exposure to loud sounds weather we produced them or were from some external source, adjustments in our listening must be made to accommodate our hearing and the rooms we grow into to get us back to how we think things used to sound or should sound.
One thing to I need to keep in mind as I go crazy chasing how I remember things sounded, is back in the day I heard music, today I critically listen and my current speaker choice, room correction and the advice I often get from fellow posters here on Audiogon has allowed me to continue enjoying this hobby as long as I don’t look at my credit card bills… LOL
As for Hearing & Listening…
Not to change the subject but… How many times has the wife come in at the part of the song you’ve waited for and starts talking and thinks you hear what’s saying, then says you’re deaf for not responding? … LOL Didn’t hear my wife because I was listening to the music….
