I was just playing Stevie Ray Vaughan's The Sky is Crying. Cuts 4 and 8 sound awesome on a good system (like yours).
Also, Dave Matthews and Tim Reynolds' Live at Luther College has some amazing guitar work on it. And speaking of Ry Cooder, I always liked his Bop Til You Drop, on LP. I believe this was one of the first digital recordings pressed on vinyl, and it sounds great in my opinion.
