CSM41, my gear is in my sig but I'll elaborate.
I use 2 pre-amps. I have the Adcom GFP-750 which is both active and passive at the flip of a switch. I use that for shorter listening sessions and movies, etc. This pre has a processor loop (for HT) that allows me to run the Dared Sl2000A straight through. The processor loop is staight pass through (no degredation) and can be activated by remote or at the pre. This works incredibly well because I don't always have to power the tubes on for music, dvd's or background music. So I have the flexibility of active/passive and tubes. I use Signal Cable Analog II I/C's to connect the Dared thru the processor loop. MIT Terminator II cables from the Adcom pre to the amp.
My source is (2) pieces, I use a Squeezebox Touch wireless music streamer which I bought an aftermarket linear power supply from Welborne Labs for, since the supplied walwart is a cheap switching power supply. I have all my music ripped in FLAC (lossless) format on a stand alone computer I use only as a music server. The digital output of the Squeezebox is fed into a heavily modded Adcom GDA 600 digital to analog converter via COAX, again Signal Cable Digital Cable. MIT Terminator II cables from the dac to the pre-amp
My amp is a Pass Labs Aleph 30 single ended Class A amp @ 30wpc. I use the single ended inputs because I think they sound a tad better than the balanced inputs. Speaker cables are MIT Terminator II.
I have a Marantz DVD player that is hooked to the Adcom DAC via coax and I use that for movies or in a pinch single cd's that I haven't ripped to my music server.
Speakers are modded Polk Audio SDA 1C's w/ rdo tweeters, Sonicaps and Mills resistors. Power cables are all MIT Z II
