Trying to eliminate hard upper midrange


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.

Hi Bowlerds,
one really cheap tweak not to be missed. Try BDR Mk3 or Mk4 cones under the preamp and/or other source components, with the cone points on the more resonant surface eg. isolation board, rack shelf or thin walled casings.
The Mk3 is said to give a warmer sound and Mk4 a more linear sound. I have the Mk4's under my preamp yesterday and was pleasantly surprised by the extended bass i never heard before. The Mk4 had not removed any hf (as predicted)significantly, but for the extend bass now, my system does not sound harsh in its new found balance. The cones didn't work well with my cdp however. If i have a great setup like yours i would definitely get a set of both Mk3 & Mk4 and experiment, you never know it might be just what you want. Btw I dont work for Black Diamond Racing.
Regards.
