Just an update on my search. It was so helpful to get everyone's input.
I've narrowed down to either switching the Arcam out for a dedicated tube pre or selling both pieces and just using an integrated. I'll get a separate DAC either way.
For integrated amps, I'm looking at the Yaqin MC-30L or Rogue Tempest. Both are in price range and come with the all important remote
For Preamps (if I keep the Carvin), I'm looking at the Akido pre that was suggested, and also the Schiit Freya and a few options from Rogue Audio.
For DAC, I've got all manner of options: Musical Fidelity, Schiit, Cambridge. Seems like lots of options there.
I think its most likely I'll sell off all buy gear and buy an integrated tube amp and a decent DAC and go from there.
thanks again for the advice and I'll update when I pull the trigger.
