Hi Fiddler. In my conversations with Rick, it seems he feels that the closer to the source you place the PC the better. I asked him the opposite question you posed, "where would you NOT put the PC if you had to skimp?" He said on the amp. I don't know if I would hardwire the PC to the component. Just a personal preference, but I like the convenience of being able to change cords or upgrade if needed. Give Rick a call, he'll definitely help you out.
I appreciate the kind words Sherod. Rick said that after break-in with his cables and cords, I would realize the true nature of my components, and changing tubes would then really show a difference. When I swapped out my mish mash of cables for an all cryo'd Audition Package the sound became slightly leaner, but opened WAY up. Last weekend, I changed out the Siemens CCAs in my Kora Hermes for a pair of Mullards and am now enjoying full rich sound with all the glorious soundstaging the Virtual Dynamics initially brought to my system. Now my Blue Circle gear display all the detail, pace, and expansiveness that I had hoped for. And with the ability to swap tubes in my preamp and DAC I'm able to tune the music to the way I like it.
So much fun!
