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.

Thank you for your suggestions. I have read all the feed back and noted all of them. I made some changes to the room and the settings on the PowerPlant. My system sounds impressive. Something to enjoy and be proud of. I am also going to upgrade my preamp to a Herron VTSP 1A or the Levinson 380S.
I found out my front end responds better to the PS2, SS5, SS6 settings. I made minor toe adjustment to the speakers . I found that the cables were not the problem even tough I ordered the XLO limited digital, I guess it would be better than what I have now. My Siemens tube are due to arrive today. I will replace them on the DAC, it should sound better than the stock Sovtek 6922.
