Cables to settle brightness

@w123ale Which PowerPlant did you get, and when? If it is not broken in, give it time. If you have a current hungry amp and are plugging it into the PowerPlant, unplug it and go straight from the wall. I’ve owned a few PowerPlants and had to do this every time. I’ve since moved to the Synergistic Research PowerCells (first the UEF 12 SE and now the Galileo) and those solved any brightness issues for me. 

Otherwise, cabling and component upgrade suggestions above also help.

Audioquest cables are probably the right cables for you.

PowerPlant is new—about a week—and probably has only 30 hrs on it so far actively playing. I’ll try plugging the amps into the wall.

Yeah, as @blisshifi mentioned I’d give the Power Plant more time to settle in.  It’s hard to believe a Mac and SF Olympica combo could sound bright, but I’m not familiar with their DACs so that might be something to explore as well.  

@w123ale Yes definitely let it burn in at least a week or two before buying new gear or cables to address issues. What amps are you using, and which PowerPlant do you have?
