Problem is that the ad/da converters are not that good. All my tones are colored for the worse. I seem to have to build a separate bank of profiles to use with this system.
Yeah Henry, it's as I've been saying - it comes down to the quality of your convertors as to how much better S/PDIF will sound, if at all, and in your case, what with the workflow / band's recording issues you outlined as well, it seems you have no choice in the matter.
I don't think you should have to edit your Rigs to compensate for this; I'd have thought EQ'ing during mixing would suffice. I'd try this first as it would surely be a whole-lot easier. Good luck man.
We can discuss it in another way too:If some people use audio cinch wires instead coaxial wires so the s/pdif can't reach the digital quality.
And to colour a sound @Michael_dk should be reserved for myself and shouldn't lie in the hand of the interface. My point of hear.
If I transfer a sound I will hear the same sound with headphones at Kemper and at interface and after recording. If not, then I don't need a interface of course.
I know you're joking, Kulle, but I hope you haven't missed the point:
Some interfaces' convertors really do sound crappy when compared with others'. Zoom would have to be somewhere near the bottom of the heap, especially older models, so IMHO you should be able to hear quite a difference between analogue -> Zoom and S/PDIF. If the interface's convertors are for all intents and purposes "transparent", then there'll be no problem using them.
Some preamps add "color" I may want in my tone.
Other preamps/interfaces do not, and result to a worse tone than going SPDIF.
... and others are transparent, which do not result in a worse tone... in theory at least, Dimi.
Just adding the third-case scenario as you've left no room between "desirable" colour and non-coloured.
