We agree with Seandtaylor99 that the Decca Legend CDs are fantastic - and we have a very high resolution system (Audio Aero Capitole mk II, Lamm L2, Edge Signature monoblocks, Valhalla, Shunyata Anacondas, Acapella Campanile Highs). The CDs are all classical music, remastered at 24/96, and are recordings of some of the best performances of the last century. In general, I find them to be better than XRCDs (we have have about 20 XRCDs here, mostly jazz, and about 20 Decca Legends so far - but have just ordered the complete set) and they are MUCH cheaper ($12 at AMZN, $13 at iclassics.com). At iclassics you can see them all together (I have not found a way to search AMZN correctly to see an exhaustive list there):
