I can recommend one NOT to get. Having no Elvis whatsoever in my collection, I decided to buy the 2013 Sony K2HD re-release of "Love, Elvis" because that compilation (originally by BMG, 2004) has the best selection of tracks for my taste, and I figured it would also have top drawer sound quality. So I rationalized away the very high price. Big mistake!
Issues with this K2HD release include unforgiving treble, annoying volume fluctuations between tracks, too abrupt fadeout endings on some tracks, having a mixture of both studio and live performance recordings (something that always drives me nuts in a compilation), and the inclusion of at least one track (the final track "If I Can Dream") which doesn't fit at all with the rest of the compilation because Elvis' voice is so different on it as compared to all the other tracks.
Incidentally, I do have a couple other of the very pricey K2HD CDs in my collection so I have some basis for sound quality comparison, and "Love, Elvis" does not make the K2HD grade. Sony, shame on you!
