I've had mine for about 6 months, and I'm thrilled with it. I haven't used the DAC or headphone amp, though. I'll use the DAC soon enough, once I get an Airport Xpress or similar.
I shot it out against my previous CD player (Cambridge Audio 840C) on Redbook format, and I felt it was just a shade better. A tiny bit warmer, maybe a slight loss of edge, but equally detailed, to the best of my ability to resolve those things. Throw in the extra features (SACD, DAC), and it was a no-brainer as far as which one to keep. I certainly haven't looked back.
