@audphile1 - Apologies for misreading and thank you for the clarification.
@gochurchgo - I like the amps a lot more than the pres for that exact reason. Even with the amps, I would encourage you to seek out something more colorful in a pre. A Luxman if solid state, or a CJ or Rogue for tubes. I’ve not heard a lot of tubes in a very long time so sorry I don’t have more to recommend.
My experience in general with ESLs for instance really encouraged a tube pre/ss amp combination and the results were pretty glorious with the right speakers. Coda/InnerSound was no exception and I imagine the benefits of sweetening up the amp with a tube pre still holds.
