It would be interesting to compare the sound of CD with a SPDIF signal from an outside source, like a Sonos or Squeezebox. Or for that matter, a cheap DVD/Blu-ray. I myself own a G91, and wonder if an upgrade to 808.3 would be adequate.
I have already noted that a CD played through G91s DVD-Video/Audio transport sound significantly better than the SPDIF-signal from my Sonos ZP90 box (see
this thread).
I wonder if this can even be bettered by a 808.3. Or will it be a huge and very, very expensive disappointment?
