For those interested. Branislav just posted a comparison between the Lampy Big 6 and the Concert Fidelity DAC-040 (without battery option):

Summary: "Concert Fidelity slightly more impressive, for what its worth, with electronic music but Lamp more musical with most everything else...wish I could keep both and maybe I will but I might have to let Concert Fidelity go in the future."
Thought that comparison belongs in this thread. It certainly fits the thread title.
