Didja try adding a Monarchy 24/96 DIP? You weren't clear as to what sounded better between your Toshiba using its internal DAC versus the MSB. In any case, jitter would be the primary culprit. Keep what you have, get a Monarchy 24/96 DIP for $150, and get a Powerbase for $225 for your Link while you're at it.
