ART Headamp 6

With six output jacks on the front panel and twelve on the rear panel, you can plug a lot of headphones with powerful output if you don't go too low with impedance.
Sound is very good considering that its main task is to support professionals in their work more than allowing silky hi-fi listening sessions.
Many characteristics make the HeadAmp 6 a pleasure to use: the sound has very low noise; the appliance is compact and seems well built, with damped knobs, no slack on connectors and not too much LEDs that may further clutter the rack.
In the front panel there are also six input jacks with mixing controls, one for each headphone channel.
