Topic: which choice between HDSPE-AIO and Fireface UC

Hello everybody.

Which choice in your opinion between :
- (the old...) HDSPe-AIO
- (the new)  FireFace UC
for the following use which is very very basic :

1 - to listen to the music recorded on my PC (XP Pro 32 Bits equiped with the last mother board Gigabyte P67A-UD5) via my preamp KRELL (the modulation goes from the PC to the unbalanced RCA inputs on the preamp)
2 - to record on my PC all my DAT digital tapes via the S/PDIF output on my TASCAM and STUDER DAT.

This is all the use I need, but I want to do it in the best conditions.

What would be your opinion as regard to the choice I have to do between HDSPe-AIO and Fireface UC

Thanks a lot for your help.
Claudius.
