What about a bigger Interface. Balance 2.0 or something.
What I have seen of the Balance Interface I like. Its good looking, has a lot of smart functions. I can't say anything about the sound, but i bet its okay as well.
But the main reason it never crossed my mind to buy it is the lack of in- and outputs. Atm I'm working with a Focuswrite Saffire Pro 40. 8 i/o are great for me. I hardly use more than 4 inputs at the time, but i happens that I use all eight of them.
So you should consider giving balance a bigger brother with more i/o. And perhaps some magical sounding pre amps. Thank you.
