A little background – I set out on a quest to get the best sounding and looking high definition sound and video I could muster on as little budget as possible.
I started with a $750 Furman power conditioner for all my audio/video/cable box/modem/router/switch equipment in my main entertainment center. BUT when you plug in cheap wall warts, even if it is plugged into a $750 power conditioner, in a way you have defeated the power conditioner, because they are AFTER the conditioner. What to do?
I ordered these (3 of them after trying one) for the last generation of Chromecast Audio streamers and 2nd generation Chromecast Video streamer.
As you probably know, noise from linear power supplies is much lower than switching power supplies. If you want to know more, put “linear vs switching power supply audio” into a search engine.
Anyway – this is a high quality LINEAR power supply. It tightens sound, represents the soundstage more accurately, helps remove artifacts and distortion from video, etc., etc.
Try it – You have 30 days to make your decision. BTW – look at the other voltages they make. You can clean up your cable modem, router, Ethernet switches, on and on. EMI/RFI is some of the most difficult noise to remove from video/audio equipment. This power supply is an inexpensive solution.
