I am using a Doge 6 since a couple of years (together with a Doge 8 preamp) and I am loving it. The only thing to know is that with this CD player the sound is not only warm, but also smooth, smoother than with other tube players.
The DAC seems to work in an excellent way – it is definitely better than my stand-alone DAC (TEAC UD501), which has also it’s qualities.
The sound is altogether very full and rich, good dynamics. I like it. Moreover the manufacturing quality is also excellent (as with other Doge products).
Marc from Doge Audio was moreover always very helpful with any q1uestion I had. I can really recommend this device (and, up to now the service behind).
