My listening experience with Avalon speakers was not that impressive. They seem a little slow and wooden sounding in the lower mid. The sound you say you are looking for, fast with high resolution, but not in your face detail, should also communicate the micro dynamics, often glanced over in the hunt for speakers. Some times the hope of finding a better sound from the same old wooden boxes ends up simply being new type of shiny drivers.
I would highly recommend Wilson Benesch speakers. Heavily relying upon carbon fiber, not for driver use but rather to add the superb acoustical properties of carbon fiber to the cabinet construction. Carbon fibers are long and can be woven to both direct the energy away from the thinest part of the cabinet, the drivers, to the back of the cabinet which on some models an aluminum spine sheds the energy down into the spikes to the floor. The sound energy vibrates the billions of molecules and moving at 18,000 feet per second, away from the front of the speaker as that energy is converted to vibrational energy part of which is converted to heat. This is how stealth aircraft avoid radar. Converting the radar to heat not letting it return to the radar.
A little long explanation but with all this technology the fear is they won’s play music. This has been a very long term project for WB. A number of years ago they came out with a model that drew acclaim as the most accurate speaker available. I was not a fan. Only a few years later they found the sweet spot make music easily accessible.
Not sure on your electronics however it might be better to get your speakers let them break in before you change out other gear. You might make yourself crazy doing that.
Just read your post again. If you live in an apartment the Benesch speakers are clean and fast. Where most speakers will double at 40 hz and the 80 Hz waves always seem to get the sheetrock moving and the neighbors complaining.
