So I bought some equipment from somone recently and they threw in the Tascam US-428 with it for really cheap.........I figured I'd give it a shot as it does so many functions at once and reviews say the sound is great for the price............

I know all the Tascam's capabilites I think but I still have my other audio interface that I'm not sure what to do with........it's a Delta 44..........now is it a good idea to use it in tandem with the Tascam or go with one of the other? I realize the Delta has a bit better sound capabilities but at this point the difference between 96khz and 48hhz recordings is not such a big factor for me..........so I wanna use the Tascam for it's other features so should I get rid of the Delta or use both (if that even makes sense)?

thanks!
