@valinar picking up this old thread. I did pick up an LFD power cord a while back. Cant say i heard a difference, but I did not do focused testing either. Probably should do that. I did get my first power regenerator recently, and that definitely made a difference, so I am a believer there.
Thumbs Up on LFD!
Wow, giving a plug for less well-known brand. Just testing out my recently purchased used LFD NCSE Mk III integrated right now. This is digital audio via Roon -> Bryston BDP-2 player -> Lampizator Golden Gate DAC -> LFD -> Harbeth 40.2.
Clearly the best solid state components I have heard in my system. Probably not as good as my ARC Reference preamp and amp combo, but very good in a compact solid state box. Good sound stage, good separation, good resolution, "liquid" sound. Is somewhat "hard" at moments, but clearly more musical and hifi sounding in my system than any other solid state gear I have tried, including First Watt F7, Luxman 509x, and Bryston 7B2 monos.
Very simple, few-feature box (no remote), but sounds pretty darned good.
