This piece of equipment is great for anyone, who is on a small budget, but has a pair of great cans.  I for one use the Headpod with Akg K701s and have achieved very good results.  The amp can get these headphones to pretty high volume levels - definitely beyond anything I could physically listen to without blowing out my ears.  It also delivers nice and tight bass to cans usually missing it slightly.  Build quality is also superb, completely housed in metal, with a glossy white finish on top.  Five volume knobs, including one master volume, top it...
