Wow

Wow, for the price it's beyond expertations. It's literally now background noise it's totaly quiet when not playing any music, even when the volume is set to maximum. It delivers good amount of power, I have not been driving it so hard, but it's obvius that I've got enough headroom when driving my DyneAudio Emit 20 bookshelf speakers to normal and a bit louder than normal listening levels.
I've got the 5A power supply for the amp.
