My Gamut is the original. I read in a post at the Digital Asylum from the designer of the Gamut, he wrote that the "revised" CD1R has an improved power supply. And that this improvement affects the midrange not bass. I had a number of audiophile friends over to listen to the CD1 and none of them thought that the bass was lacking. Again, the strengths of this player are balance (no bass or treble boost), lack of digital edge, and soundstaging. All of which the Wadia does equally well or better, but at more than twice the cost.
