Hi Powder:
I currenlty own the Concert Fidelity CF-80 preamp, the Silicon Arts ZL-120 Monoblocks, as well as their Phonostage SPA-4B. I agree with you, these electronics are incredible. To answer your questions, I am using a "Matched Set" of Mullard Tubes (Which is what Olsher found to be the best match with the CF-80 Preamp).
In terms of speakers, I am using the "Venture Excellence Speakers". I have owned a number of speakers, and the speed, resolution, and realism that Venture Speakers offer nothing in my experience matches. They are an excellent match with Concert Fidelity/Silicon Arts Electronics (These are the speakers typically featured with their electronics at shows, and it is the system that Dick Olsher picked as best of show at CES twice in a row).
Hope this was helpfull
