I am listening to the Sacred Treasures I CD right now. Yes, it is an excellent recording -- the rendition of the cathedral ambience and choral imaging are both impeccable. The Russian cathedral bell at the very beginning is almost scary! This recording also sounds excellent in DPL II Music 5.1. The only nit I have to pick is that most if not all tracks have a significant noise floor (tape hiss); this must be an ADD or AAD disk (surprisingly for a "classical music" CD, the jacket does not specify the recording mode). Nevertheless, this is an entirely enjoyable CD, especially late at night. I look forward to receiving the series II and III CDs in 3-4 weeks!
