Upper Midrange Glare problem


I am seeking advice to eliminate hard upper midrange glare. I spent alot of money and the sound improved, but the glare is still present. Is there something wrong with my set up, or etc? My systems is as follows:

Counterpoint DA 11.5 transport with Shunyata King Cobra.
Sonic Frontiers SFD 2 MK II DAC with Shunyata Black Mamba.
Sonic Frontiers SFL 1 Signature Pre Amp with Shunyata Viper.
All above components connected to the PS Audio P300 with a Shunyata King Cobra attached to it.

Bryston 7B ST Mono block with PS Audio Lab Cables connected to two Ultimate outlets which is connected to XLO Type 10 powercords to the wall outlet.

Speakers PSB Stratus Gold, placed 3 ft away from rear wall 2 1/2 ft from side wall, room is 15'wide 21'deep
8 1/2tall. Listening distance is 9 ft away from speakers.

Cables:
Digital - Illuminati D60 - BNC and Illuminati DX-50 - XLR
Interconnects - AudioQuest Diamond X2 - RCA
Speaker Cables - AudioQuest Dragon to highs and Clear 3 to bass.
All Cables are raised by ceramic tiles.

Brights star foundation platforms, tip toes, for each component sitting on a Stand design rack, set of room tunes corners, side walls and tune stripes.

New additions will be XLO limited edition XLR digital cable and Siemens CCa tubes for SFD 2 MK II. Will be here shortly.

Very fraustrated. Any suggestions will be openly noted, thanks.

The glare could be caused by any of the above or a combination of them. Something cheap ($3-$4) to try would be to pick up a small piece of wool felt at a fabric shop along with some double sided tape. Cut rings out of the felt to go around the tweeters (approx. 3" wide, so that they can later be narrowed for less of an effect) and mount them with the tape. Sounds stupid, but it can sometimes be very effective (smoothing) in the mid to upper registers.
JC: When using a mirror to locate the first reflection point, how much of the wall area needs to be treated (is their a reasonable minimum)? This has always confused me.
Sean: I somewhat remember the cables that you are talking about which were very inexpensive. Please re-list the source of them, if you will. They sound like they might be a good choice for the few new posters that are just starting budget two and multi channel systems as well.
Thanks JC: I will start with my 6' and 5' tall (foamcore) free standing Empire State Building and Sears Tower. They won't do much good from the listening position on the sofa, but should be easy to place for near field listening.
JC: We coudln't find a tiny King Kong, so placed "Lambchop" up there instead (good place for him/it/she if you ask me:-).
