Hi guys, I'm currently using a Line6 Toneport UX1 for my recording and am not really satisfied with the results. I was thinking of getting a DI box to put with the interface but after reading up on this forum it looks like upgrading my interface would be a better idea. I'm looking at either the Saffire 6 USB or the Saffire PRO 14. Is there any reason why I would choose one over the other (eg. is using Firewire better than USB)? Similarly, is there any reason I'd choose the PRO 24 DSP over the PRO 24? Thanks.
