COMMENTS
The article states, "...it was little more than a tick from the main speakers and a bip from the subs. I only heard it from the unbalanced inputs—it was absent when I hooked things up with RCA."
Kal, I suspect that you had intended the word "balanced" rather than "unbalanced" in this, if the problem went away on the RCA terminated interconnection.
Thanks. Actually, it really should say "I only heard it from the balanced outputs—it was absent when I hooked things up with RCA."

...keeping the audio interface separate from the separately replaceable and upgradable computer and software.
I prefer the idea of having the multiple input options on the s88 without additional boxes and cables.
Hi Kal,
I'm looking to make a major upgrade to my current multichannel DAC (Oppo 205). For 5.1 SACD music (harder to convert / download to files), would it make sense to use the Oppo 205 as a transport and send the files digitally to the Exasound from the Oppo? I plan to start burning multichannel DVD-A's and Blu-Rays to a NAS down the road but want to know if the Oppo digitally into the Exasound will produce strong results on par with feeding the Exasound with NAS files. I've learned not to assume anything. Thanks, Gary

I do not see how that is possible. The only MCH outputs from the Oppo are HDMI or analog and the exaSound will not accept either.
