great little usb dac/amp. I prefer it over the Fiio E7. Under warranty still with a few months to go. The power on LED is intermittent, but doesn;t effect the sound of the unit. A little tap will make it light up or go off. To fix the LED, I'd have to ship it to iBasso in China, and the postage isn't worth it to me. Comes with original box, warranty card, and usb cable. Free shipping in the states. Please gift the paypal payment. Thanks.
