I use it for a few weeks, I tried a samson before, but they are based on the same operational amplifier, only the channels change.
opportunities are attractive, Front AUX, 12 headphones manageable

it is not expensive, and frankly for a small home studio, it's really very good!
course, we feel that the quality of manufacture is not a standard utlisation intense and caution, but a headphone amp does not troll around!

I carefully considered my choice and knowing I'd do it again!
you just know what lo'n wants is a product intended to be fixed, manage headphones, and not of HP.
I did not notice any saturation or breathing, even pushing the knobs. I drive the Sennheiser HD560 (old high end), hd 477, hd 515, hd 201, hd 450, hd 435, and no problems, we come easily to match the levels.

short, a very nice vehicle to advise! but being aware that for the accurate recording, you need a more accurate monitoring than him.
Me, I plug my best headphones directly to the mixing desk to monitor, since the powerplay connects the output line, he!
