I am a bit confused by Apogees information sheet. On their spec sheet they state that the regular Mini-DAC takes a USB input. But in their blurp advertizing cost they state that USB and Firewire are optional. But then they only seem to have a Firewire version as the only upgrade.
Is the $795 "regular" Mini-DAC inputed via S/PDIF (of these three choises USB. Firewire, and S/PDIF)? Does the Firewire option include USB?
Is Firewire sonically superior to USB and S/PDIF, especially in regards to reduced jitter?
