Ultimate Audio Upgrade

No, not something from Machina Dynamica. I made the big plunge in my next step in music appreciation. I purchased a cello and am learning to play! Seems that after several years of audio listening I continue to want more and more. The last time I got so excited was when I listened to a pair of Verity Parsifal Ovations driven by a VTL 6.5 and MB 450's and dcs SACD source. And they didn't even sound as nice. And the cello was a little less expensive. I would be interested in peoples recommendation of cello music that is "outside the box", bluegrass, jazz, etc so that I may expand on what might be possible with this instrument. I would also appreciate anyones experience with picking up an instrument late in life. Thanks, David.
