MSB Link DAC III, yes. The previously described setup is -- SACD/DVD transport with analog outputs plugged into analog inputs of DAC, then listen to outputs of DAC. If there's no digital input to the DAC, then it plays through the analog inputs, so there's no plugging and unplugging necessary, but a small amount of deterioration due to the additional connections.
That's my home system, which I hardly listen to. My work system is the 3910, pretty much.
The Apollo is currently not being used. I'll probably hook it up to my speaker rig once I fix my vintage Pioneer SX-5590 receiver which blew an output. (It sounded pretty good right up until it blew the output -- had it refurbbed with black gates.)
