Yes, I forgot about that. Some slight changes to both over the years. The Little Dot also changed the Hi Gain from 8 to 4 as well. It was 500mw into 32ohm, now it's 300. Still plenty of power.
Either one at $100 is a great buy. The C&C has a slightly bigger soundstage, the Dot has a deeper tighter Bass and a tad cleaner from top to bottom, plus a little more power.
It really comes down to flavor. Myself pick the Dot, for the cleaner sound and power. $100 is not a lot of money for a great amp, either way!! I'll give the C&C a plus for the battery being able to be changed the Dot is soldered on.
