Not yet. I've got Ormandy's version of Carmina Burana, but I'll take your recommendation and give Slatkin's rendition a try.
WRT the system - that - aside from the north Idaho spread I bought a few years ago - was my one big self-indulgence after walking away from Microsoft. I've got about $28K invested so far, and it would have been more if I hadn't made some practical choices by buying part of it used. About half the cables, the LS22R and the CD transport are used. There are some great bargains out there if you know what you're doing. AudioWeb.com is a good place to shop for used gear. I've also got a review of the Pass X350 out there.
At some point, I'd like to upgrade the system to the latest version of the Magnepans (20.1Rs), An ARC REF-2 preamp and a pair of Pass Labs X600s. Now that'll rock. If music be the food of love...
