With a clean power supply, you will achieve a perfect "black" background and you will not lose the finest details. Your home system will sound much better. PowerQuest 2 is a very interesting solution for demanding music and home cinema lovers. With this device, you can optimize the entire system at once - including AV components - and at a price that everyone can afford. PowerQuest 2 brings a range of advanced Audioquest solutions that clean your power supply of high frequency (RF) and low frequency interference (hum and other network problems). Audioquest PowerQuest 2 filters signal interference for audio and video players, displays and other parts of the chain. Two of the six sockets are not filtered and allow the connection of high-performance components (amplifiers, subwoofers or active speakers without actual compression). The icing on the cake are two high-speed USB charging ports, through which you can quickly charge your mobile phone, tablet, Bluetooth speaker, headphones and more.
