RCA's.....so what? I run eight in and eight out thru a Mackie board with a ten foot snake with RCA's on one end and 1/4 inch on the other. Cost about $35. Certainly no difference in sound quality.
Yes...you can add tracks to your 1680 with the VSR. In fact, it may be the cheapest way to do that at about $400 for eight additional tracks. The VSR can be a slave to to your 1680 which allows you to use your faders to control the VSR's tracks. You get 4 gigs of useable hard drive space.
The VSR has eight virtual tracks assigned to each "real" track and two banks to work with so you really get 128 tracks...!
