I am not Thomas, but I thought I'd chime in in support of
what Christine said about optical. I like the idea of electrical
isolation between the PC and the stereo, and if you're
reclocking at the receiving end, you don't have to worry
about jitter.
Another great thing about optical -- you can use really **long**
runs of it. I've had no problems at all with 50-foot Hosa
optical cables. Your Mileage Might Vary, I suppose, depending
on the details of the S/PDIF (or ADAT -- I've used both)
transmitter and receiver, but I have yet to have any
problems that could be attributed to using long optical cable runs.
Optical is light (no pun intended) and flexible, too.

Long runs are a good idea - Christine Tham 10:30:05 02/21/07 (4)
It means the PC can be positioned far away (perhaps even in another room or the attic/basement) which reduces the possibility of EMI interference with the rest of the system.
WinAmp for example can be controlled via a web browser - any Wi Fi PDA can do that.
This almost makes me feel like rushing out to buy a DA10. Except I'm already pretty happy with my current system :-)
- A short run is all I need but I like the electrical disconnect advantage anyway - dave in gva 11:02:59 02/21/07 (3)
  Thanks Jim and Christine. My plan is to have the PC, DA10, and integrated amplifier all out of sight and sitting adjacent to one another on a shelf I'll build in the basement, just below the listening room. The amp and DAC will be powered off one of those master/slave extension cords with the PC on the master outlet, meaning that when the PC is shutdown the DAC and amp will automatically power down as well (and repower on when the PC is remote booted via a wake on LAN call).
  This means I am talking about very short runs on the interconnects between PC and DAC, and DAC to amplifier. The longest run will be the speaker cables off the integrated amplifier up through the roof of the basement into the living room, but even this run will be on the order of 2-3 metres max. From what I've read on cabling discussions one is better off with longer runs of speaker cables than equipment interconnects.
  So the only evidence of an audio system in the listening room will be the speakers. I'm not thoroughly decided on remote control but at this point I'd have to say I'm inclined towards a UMPC that accesses the remote PC via the remote desktop facility of Windows XP. I'm planning volume control via this as well by asking the remote PC to fire an IR blast (it will have a USB based IR transceiver) at the integrated amp. This latter process can be accomplished with something like Girder on the remote PC.
  So I feel like I am closing in on the architecture of the system. These threads help enormously. Thanks for allowing me to benefit from your experience.
  Best,
  Dave M

    If everything is in the basement anyway, there's no need for the three components to be next to each other. In fact, the further apart they are, the less the chance of EMI interference between them. You don't need to be on opposite ends of the room - even a few feet/metres may make a big difference.
    And you probably want to avoid powering the amp and DAC using the same circuit as the PC, for reasons already discussed (possibility of interference).
    What you can do if you are really keen is:
    - power the amp and DAC using a dedicated power line, and put some filtering/condition on this circuit.
    - the PC can be powered the household circuit, and turns the amp and DAC on and off using X10.
    - volume control can be achieved using IR blasting as you suggest
    - Thanks will give it some thought.....whats X10 (nt)? - dave in gva 19:54:14 02/22/07 (1)
