Is it better to use s/pdif or anologs ins and out ?
The Question is what you like better, not what is better.
I think you have to make clear what you mean.If you just want to "Edit" something it is better to transfer it via Digital i/o (or smidi).
If we talking about Recording/Soundesign there are different ways.
In particular the Digitally transducers D/A from the old E III and Emax 2 ( there are many People out there with this meaning) have a special Sound- Character in connection with the Emu Filters.
I had Experience like this with my E4XT output Extention. Longtime i connected my Setup via the Adat i/o , after a while i had to
tried instead of them the Analog OutPut Extention ,( because my AudioInterface had not enought i/0 etc) ,and the Filter-Sweeps sounded Realy different !. Specially the Morph-Filters came very different via Analog than Digital.
But it?s Subjectively. It?s Soundesign . It?s up to you. Try it.!
That Emu ;-)
