Marco, the easiest way to record your vinyly is to take the output from your pre-amp into somrthinh like the Rowland A2D/D2A and then plug it vias USB into a laptop. Then use Audacity as the recording software - job done.
Thanks, Mark. I'll bear that in mind. However, since I've already bought the EMU sound-card, which I've been informed is good, I'd like to persevere with that for the moment.

If in the end it doesn't work properly in my set-up, then I'll obtain the Rowland you mention, and do it that way

Marco.
