At work I use a different rig than at home.
I tried two different setups:
Foobar WASAPI -> Firewire -> Firewire 410 -> Optical -> d10 (headphone out) -> Gilmore Lite -> cd3000
Foobar WASAPI -> Firewire -> Firewire 410 (1/2 Output) -> Gilmore Lite -> cd3000
For a few days I listened to the first setup and was pretty pleased, after I finally got an adapter hooked up to the fw410 to use its outputs...
I found that the d10 as a DAC via optical fared worse than the fw410 as a DAC; it was like the bass wasn't as well rounded on the d10 and couldn't keep up. I could also hear more coloration with the fw410, especially apprent with extreme high frequencies (it kind of hurts) as a result of this. I would venture to say too that the detail was better with the fw410.
I do recognize that volume matching at that point gets difficult, but do you guys think that there's some flaw in my setups here or would this seem accurate?
