My final choice is PreSonus Studio 68c - can't find many videos with this exact model,but considering preamps are a step up from cheaper Studio 24c,which has this clean,transparent sound i was after,expect Studio 68c to do the job - don't need all inputs and outputs,but 24c has undefined preams probably limited or something XMAX-L instead of XMAX.
I am kind of fan of presonus since use Eris E5 monitors and probly wlll continue with this brand.
Cheers
