iFi Audio GO Bar Ultraportable DAC Preamp Headphone Amp

Very good sound & build quality. It's really small, but very solid.
It would be good if the LEDs and the labels were bigger. But that's not a big issue.

good portable DAC and amp for any earphones and headphones. its smaller than you expect. it has a lot of options and has analog bass boost which helps with headphones that don't have much. also includes small cables let you plug it into 3 different devices... PCs/Macs, android phones/tablets, and apple iPhones/tablets. Electronics for less shipped it two hours after ordering, and its as there right after the weekend.
