Forget going from the Firewire 410 into an external DAC. The DAC within the Firewire 410 is a fantastic Audiophile DAC in my limited experiance, and it is capable of handling high resolution 24-bit 96 kHz sampling rate through all outputs, and up to 24-bit 192 kHz outputs via the analog outputs 1 and 2. You will be amazed at the sound quality. Of course you will need a couple of male 1/4 inch phono plug to female RCA adaptors, which are available from Radio Shack for about $10 to output to your stereo system.
