Actually I'm not sure if i2s is a deal breaker or not. I'm looking at the MSB Discrete which I don't think has the option for i2s but then again it has modular input cards.
If I could afford it I would get the Emm Labs DA2 V2. But my budget is about half that right now. I'm just not sure if the MA3 will beat out an MSB Discrete, plus I can upgrade it so I think it would last longer?
