I have most of the RCA-derived XRCD2's, and they are a significant improvement over their conventional CD counterparts. The best ones are the Reiner Bartok Concerto for Orchestra (just breathtaking), the Reiner Respighi (much smoother and fuller than the Living Stereo CD), and the Reiner 'Iberia' (which, BTW, has no Living Stereo equivalant--the XRCD2 blows the older CD issue away completely).
