I'm surprised nobody's mentioned the new Telarc SACD with Donald Runnicles & the Atlanta Symphony Orchestra and Chorus.
Perhaps some Carmina freak out there will see fit to take issue with a particular aspect of the performance, but overall it seems to capture the spirit of the music exceptionally well--and everyone I've played it for (audiophile and civilian alike) thinks it sounds fantastic!
The disc itself is a hybrid, with a regular CD layer and an SACD layer (containing both a two-channel and a multi-channel mix). The recording is pure DSD (essential if you want to hear what SACD is all about). I've only listened to the two-channel SACD mix, so can't comment on the multi-channel mix or the Redbook layer.
Folks who have yet to be impressed by SACD ought to give this one a try. A megabuck setup is definitely not required: any half-way decent system (good subwoofer highly recommended) with enough juice to attain realistic SPL's ought to absolutely electrify you. If not, something's amiss with your equipment, or perhaps you just need to have your neurotransmitters drained, flushed and replenished.
