Currently have a PS Audio BHK 250 Signature, but am finding tubes really aren’t my thing,
No, you're finding the PS Audio BHK 250 Signature isn't your thing.
If it was the tubes, then all amps running the same tubes would sound the same. Which, spoiler alert, they do not.
For what that amp cost you could buy an integrated from Prima Luna or Raven, sell your overbuilt overpowered monstrosities and superfluous preamp, ICs and power cords, and have better sound with money left over.
