The best acoustic guitar recordings??

Ottmar Liebert - solo Para ti

Check out The Romeros on Mercury Living Presence for a special treat.

José Luis Montón's "Solo Guitarra" recording on ECM is a recent favorite and recommended to those who like a modern take on the flamenco tradition.

Rodriguo y Gabriela. Beautiful, electrifying, great music and their albums are nearly all reference quality for showing off systems...kinda the best of both worlds for me.

2 acoustic guitars playing Spanish, rock, elaborate intricate and fiery renditions of Dave Brubeck...these two are super-creative. their Live in Japan album is great.

Not sure if it's been mentioned yet, but Ry Cooder and VM Bhatt "Meeting by the River" is very interesting music by 2 great players. It is beautifully recorded, too. Cooder plays guitar, but Bhatt plays a variety of acoustic stringed instruments from India - so it is just a little OT. IMHO, it's well worth checking out and in the spirit of the OP.
