Help! Replace my VCI 300 with an s2?

It is hard to argument against the S2 as NI has made the prisedrop.
So you might do fine with that.
But if you want a really grat unit that has a hardware 3 band EQ for the mic and a broadband echo built in in the unit 🙂
There is the Denon MC6000 and as well as I know, no other controller can match the MC6000 when it comes to mic performance!
