Matt,
We are actually in full agreement.
When I put up this list :-
"1. Cool, dry, lean, thin, fast -> FIR1/2
2. Warm, slow, boomy, laid-back -> SDLY 1/2
3. Balanced - DSD",
I meant that the settings to be used depends on the overall sound of a system or recording. So, if cool, dry, etc -> use FIR. If warm, slow, etc -> use SDLY. And in a well balanced system, the DSD setting is best.
Hope this clarifies.
As to your finding that the ODSE is better as a straight DAC, I predicted that in several posts back. :) What might improve your current SQ is the addition of a usb-spdif converter from the mac mini to the ODSE.
Cheers! J.
