I received my REGEN amber last night. I was able to listen for about 1.5 hour and with stock switching psu. Holy f**king sh*t. This is at least as good as improvement from going from a crappy Sovtek 2A3 tubes to EML or even more. I don't know if it'll sound even better with time. But I'm waiting for my linear PSU to arrive that I'll use to power the REGEN. According to feedbacks from computeraudiophile, linear PSU should further increase the sound quality.
As much as I love my Lampi, I don't think the amanero based USB input does justice to its capability. Maybe that's why REGEN has such an incredible positive impact if using USB input. But then again, everyone is reporting how awesome REGEN is with all sorts of dac. All I know that, anyone using Lampi should try the REGEN before reaching for the uber tubes.
