I am a huge fan of both Shindo and Devore O/96s...I visited two different dealers of both brands, and at my assigned dealer, heard the combo. I know many on this forum love the combo and think they are a great match.
They were NOT the best combo in the one instance I heard them. And both dealers, both of whom I trust, told me AHEAD of my listening that they felt there were better pre/amp combo brand pairings for the O/96s, and both dealers are obviously big fans of both brands. I heard some similarly priced Auditorium 23 speakers with the exact front-end/Shindo pre/Shindo amp, right after I heard the O/96s, and the combo was much better. At the second dealer, I heard the O/96s with some different amp combos, and they sounded much better.
YMMV, but from my two experiences, there might be a better pre-/amp combo than the Shindo if you're really looking to get the absolute most out of those speakers. I would definitely try to hear the combos before you spend that much without a listen, and call around and speak to multiple dealers around the country and ask them for their honest opinions. BTW, in either case I do NOT feel I was being upsold...
