I second the suggestion of Sim Audio. Not only did Totem commonly use Sim components to demo their speakers, they actually collaborated on an integrated amp called the Totem Amber which was built by Sim Audio.
Full disclosure, I currently have a Sim Audio W3 listed for sale on US Audio Mart, so I am somewhat biased, but the Totem Amber was essentially a W3 strapped to one of their pre amps. Shoot me a direct message if you have interest in learning about the W3 or recommended pre-amp pairings. I think the W3 combined w/ a Tube pre might be an even better fit for you then the original Amber.
