Sbooster, formerly known as Squeeze-upgrade, is the first Dutch company that is specialized in the development of Plug & Play upgrade products for network music players, headphone amplifiers and or D/A converters. The upgrades are suitable for practically all product with an external PSU in the music chain including the network.


All in all I’d highly recommend the BOTW P&P ECO BOTW Power Supply, its a sure way to obtain increased performance from any product with a less than bespoke off-board PSU.
