1-06-2024....A little over a year ago I picked up the Rockport Arrakis 2 speakers and CH Prcecision M1.1 Mono blocks. Also "newer" to my system is the Allnic L10000 preamp and Nordost Odin power cords, and I added some more acoustic treatments to the walls. The room is serviced by a dedicated Equitech sub panel with seven dedicated lines feeding the room with balanced power.
The recent addition of these little plug in wall conditioner/filters from Nordost and the Puron are very worthwhile tweaks.
8-19-2015....System totally rebuilt from ground up. Moved to a larger room in basement. Room is 18'x 31' with 10' ceilings with seven dedicated circuits feeding into a dedicated wall mounted Equi=Tech subpanel.
4-30-2019.... Finally added proper room treatments focussing mostly on diffusion. All products from GIK Acoustics.
Mike, it would depend what you're using as "art". Canvas as a material isn't the best thing but you could use other more "transparent" material over a canvas stretcher and place some Auralex foam behind it. It would at least look decent in your nice space as well as providing some benefits from an acoustic dampening perspective. Let's see what the professional suggests and very interested in what you do at the end of it all. Good luck!
