If it is to be only one, then this!

Absolutely striking combination that connects with rare marksmanship hit singles with the truly great Abumtiteln. Where available, also excellent Stereo mixes were used. (Exception: "Mothers Little Helper" is available only on the UK version of "Aftermath" in stereo, "Play With Fire" and "Get Off Of My Cloud" currently do not.)
Excellent remastering, the SACD layer brings some significant benefits in terms of naturalness and liveliness. Therefore: Buy SACD and let the normal CD on the left. The hardware can be upgraded later, the present hybrid SACD here's run on any CD player.
