Hi punkaroo,
I hope you don't mind a message out of the blue, but I've been wondering about the performance of the devilsound with a tube amp, relative to other quality dac+amps, particularly the ibasso D10- two items that you alone seem to possess in the head-fi community. In HeadphoneAddict's review of the well-regarded EF2 hybrid tube amp (with a pico dac), he mentions that he preferred the sound of his D10, which was surprising. Do you find that the D10 usb dac+amp compares so favorably to a hybrid amp with a decent dac like the pico? Or does the devilsound provide a major improvement over the d10 usb dac (in case you've done direct dac comparisons)? Or could the EF2 amp just suck compared to the d10's or a different hybrid, like your Millet? Sorry to ask so many questions, but I am about to part with a lot of money on either the D10 or devilsound, and would like to hear the impressions of someone who has heard both.
