Purchased 12\/10, used ~2.5 years until my system changed; stored in a closet ever since. This handsome device with a pretty blue light works flawlessly & does exactly what the manufacturer claims. Here's a relatively recent review: http:\/\/hometheaterhifi.com\/reviews\/audio-accessory\/accessory-misc\/ade-24-1-analog-digital-enhancer\/. Don't have orig. box, but will pack securely w\/print of the pdf manual. Selling for $150, includes shipping and Paypal.
