Focal sopra 2/Gryphon Diablo 300 not good match

Hallo Friends. I have the Gryphon 300 and the focal sopra 2 playing together with an Aurender n10 streamer.
I thing the most fatiguing system. I don’t know why. To much highs..absolute no synergy between bass and high frequency..
Can’t hear it more then 10 minutes. Have also the Isoacoustics Gaia 1 installed.and quality speaker cable’s from jorma. And Wireworld power cord. 
Any Suggestion?

I own the Focal Sopra 2's and I would not describe them as bright sounding.  
But, I have Stillpoints Aperture panels at the first and second reflection points and also ASC tube traps in the corner.
My guess is there is an impedance mismatch with the amp and speakers.

I agree with @d2girls. The idea that you are going to fix your sound with a server is pretty illogical to me. Get your matching and sound right by matching your amp, pre, dac and speakers. The server is more of a final touch if anything I dont see it as a solution to problems with timbre.

All opinions are welcome.
I tried not to place the speakers so far apart from 3.5 m to 3,1 meter. With more critical listening.i think I have more boomy bass now. But still can’t find the mid bass ( this smooth mid bass). They are now 1.4 metres away from the front wall. I also don’t know about the opinion of audiotroy. It’s because he is like an Aurender “hunting killer” as I
I have read many of his posts in the forum that he criticize very strongly Aurender.
