My old rig was just CSB's > Sharp MDMS722.
I've made tapes that sounded FANTASTIC. Search db.etree.org for Spiritualized at the Fox Theater in Boulder in 2002. A few people mention that show as the best sounding AUD Spiritualized show they've heard.
Granted these people aren't tapers so they aren't as anal about sound quality. But you still can pull some pretty decent tapes if you stand in the sweet spot.
I too would suggest the JB3 over the MD, but I haven't tried a stealth recording with the CSB's > JB3. I understand if you do analog in on the JB3 that it doesn't sound to great compared to using the optical in. I dig the easy transfer though.
Good luck,
