A little off topic from the most recent posts, but just thought I'd share something with you all.
On Friday, my local authorized dealer/integrator was back to install a Savant home automation system, which is pretty amazing so far, but not entirely complete - it's a pretty complex process on their end, so there are a few bugs to work out as well as additional functions to still add. We're getting it not only to control the entire HT system, which I use for LPs, Apple TV, Cable TV, all digital discs plus USB stick files on an Oppo 105D, and with various separate connections between the Oppo and the Foundation, but also to control lighting, alarm system and thermostat. And we live in a 1420 square foot condominium! I use a wheelchair though, so it'll make things easier for me . . . and for my wife more importantly! She jokes about the six remotes we have . . . not including her!
Anyway, I had the Oppo connected by RCA analog cables and by HDMI. I was using the RCA analog cables over the HDMI for 2 channel though because, at least to me in my system and room, I liked the results more than using the Foundation's internal DAC with the HDMI connection. So, while the dealer was here, I pulled out an decent s/pdif coax cable that I was not using and asked him to add that to the digital 1 input and assign it to "BD1" on the remote so I would have a third option, and I have to say it's now my favorite for 2 channel digital sources. While I still think the Oppo's internal DACs produces a wider sound stage, using the the Foundation's internal DACs with a decent s/pdif coax cable is very close in that regard and oh soooo much more refined in all other respects. Deeper sound stage front to back, and smoother, with no loss of detail. YMMV, of course, as it's all about system synergy and room interaction, and we all hear things slightly differently.
Also, I played a 2 channel SACD though the coax and the Foundation registered that it was receiving a DSD signal, so I need to follow up with my dealer or Krell on that since I thought DSD would only pass through the HDMI.
