The PCI interface card I'm looking at buying (the RME Digi96/8 PAD) has only UNBALANCED analog inputs. Almost all the threads I've read here talk about the advantage of going all balanced. Should I drop it from consideration or is the lack of balanced inputs not a problem? Similar alternative cards like the M-Audio 2496 support both balanced and unbalanced. Open to other interface hardware suggestions. Only need two channels for voice-over work. Thoughts? Recommendations?
