Help to pick redbook player

I want a player mainly for redbook CD listening, but SACD, DVD, DVD-A or changer would be a bonus. I narrowed my choices to these players. I might would have to get two players. I have no opportunity to audition most of them so I am asking your opinions which one has best redbook CD playback, perhaps in decending order:

1.Arcam CD72 - $500 used

2.ROTEL RCC-1055 CD changer $500 used

3.Yamaha DVD-S2300 SACD/DVD-A/DVD $800 new

4.Philips 963 SACD/DVD/CD 192upsampling $360 new

5.Sony 222ES changer SACD/CD $300 used

6. Rega Planet 2000 $550 used

Are they all pretty close in terms of redbook playback quality or some stand off much more? Thank you!
