I've only ever used expensive interfaces like RME, Universal Audio and Apogee... Then tried this interface by recommendation. This is worth much more IMO.
It sounds great (using my external pre's obviously), and the AD/DA convertors are top class! It's stable, and operates without flaws... That goes for Mac and PC.
I've been in this industry a VERY long time, and Presonus knows what they're doing in terms of interfaces and control surfaces... Well done Presonus, at this price I should be buying 2.
