The "gold standard" I've always read about is how amazing the mic preamps sounded. I thought "Sure, what big difference can there be with my 788T/664/633?" Wow, they really sounds different.
We all know Sonosax makes great sounding mixers. Their strategy of releasing the R4+ and slowly implementing firmware updates to fulfil it's full potential was something I anticipated and eagerly await. It is an unusual way of selling a product compared to the other brands, one that has drawn lots of flak, but how I long for the day, and I hope it is soon, where we will have the last laugh.
