Mapman, I can't say how happy I am to hear your testament. Class D has got such an undeserved bad rap over the last 7 years.
It has been my experience that a great class D amp requires great everything else. By great, I don't mean expensive necessarily. The Fire preamp was made to work with the demands of a class D amp, but it also is superb with any other fine amp. Almost all tube amps match well to class D.
I still use Speltz's Anti - Cables for the ICs. I have found very thin ribbon SCs to be, by far, the best SCs.
