Hey, Regarding the power supply issues it really depends on who you want to believe, I would suggest do some research for yourself. I have read comments on YT and on this thread that point out various reasons why there are psu, there were early teething problems hence the units now being shipped with mains filter. My unit just arrived and I have to say straight out the box it’s disappointing as the binding posts are awful, they are really tiny and cheap. Anyway I’m gonna see if I can set it up. Fingers crossed!
