I was also wondering the same.
I recently bought the studiolive 32 iii.
I was very concerned about sound quality. I have been using a MOTU 16A for past few years. The sound quality of the 16A is STELLAR!!
I did considerable listening tests with different material, monitors and loudness in hopes of gauging where the SL fits in. In past, the motu won hands down vs focusrite interface.
Here is what I found...lol...ymmv.
Motu had slightly, again...slightly more Air and hi end definition. The SL had a slightly tighter and more pronounced bottom end. Since I was, at times, finding myself indecisive about which I liked better...I was VERY pleasantly surprised at the studiolive!! It made the cognitive dissonance phenomenon obsolete where the purchase of the studiolive is involved!
I am really impressed with and happy to have bought this amazing piece of gear.
If others have compared the SL with other hi end sound units, please share.
Peace!.....we all need it more than ever at this point.
