There really should be a Lampizator thread. I have the gen 4 level 4.5 (level 5 PCB) and it's outrageously phenomenal. Whether with electrostatics (SR007, SR009, HE60) or dynamics like HD800, HE6 and LCD 3, it's a marvelous listen and allows one to forget about upgrading for a while. When I first heard the Master 7 it clicked for me and I found I preferred it by a great margin to the PWD MKII I & W4S Dac 2 I owned then. Apart from the Lampi, I've yet to hear a DAC that sounds more natural and pleasant than the M7. Yet, the Lampi trounces it to my ears, particularly in the areas of weight, texture and openness. I also have an Offramp 5, which improves considerably upon the Lampi USB section and does wonders for the M7 as well. There really ought to be a Lampi appreciation thread...
