Focusrite is a UK brand more well known to professional musicians than audiophiles and/or home theater enthusiasts. However since the release of Apple's iPad, Focusrite has begun making products aimed at Apple and/or iDevice enthusiasts. This has opened the brand up to more mainstream consumers as many of their iProducts have solid consumer applications.
Their iTrack Solo, while designed to be an affordable, portable, recording device, it can also serve as a cost effective headphone amp for audiophiles or headphone enthusiasts on a budget. As convergence marches forward you can expect to hear more from this pro audio brand.
