Preamp Advice Needed - Gryphon Amp - Currently ARC Ref5se


Hello
I am currently running an ARC Ref5se (which i had enjoyed with various ARC Ref amps).

I now have a Gryphon Antileon Signature amp.
In comparison find the set-up a little dark or rolled off in the highs.
I tried a PASS X2.5 in place of the Ref5se and the top end opened up.

Does anyone know of other pres which might match or surpass Ref5se qualities but help the Gryphon top end open up a little? SS or Tube.

Any thoughts would be very much appreciated.

Thank you.
Yes, I would prefer balanced operation from preamp to amp.

I am vinyl only, current setup:
Techdas AF3
Herron VTPH2
ARC Ref5se
Gryphon
Wilson Sasha

My friend has this Gryphon Antilleon Evo Signature with Wilson Alexia MkII and with my passive pre feeding it, it is pure magic with all the highs and lows and dynamic slam you could wish for.
My opinion is your tube pre or phono stage is rolling off the highs.
