In my system, I tried the Audiolab 6000cdt and Denafrips area 2 and the Marantz hd-dac1. Neither produced a better sound for Redbook cds than my Jolida JD100 CDP that was modified by Modwright 3 years ago (changed the 12ax7 tube circuit to a 6922 plus some other upgrades). In total, I spent $800 for the player and the upgrade.
If you're looking to play just cds and not stream, I would find a CDP that plays all your cd types. Ayre would be my first choice if they do sacd and Redbook, but you'll have to get it used. Awesome equipment with great service. Good luck. Feel free to pm me.
