Originally sold, but buyer backed out. Fantastic all digital 100 wpc integrated amplifier with an outstanding DAC as well as the Bluetooth dongle. From the NuPrime website; 'The NuPrime IDA-8 consists of an ultra-low-noise integrated amplifier and digital-to-analog converter that decodes USB PCM 384 and DSD 256 with the convenience of wireless audio in a small, handsomely designed home stereo component. NuPrime's new Class A+D hybrid amplification technologies deliver the substance and warmth of Class A amplification and the efficiency and speed of Class D technology in a milieu of un-measurable noise. The IDA-8's spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to be believed.' I barely used it in a second system - it has very few hours on it. I have far too many amplifiers and need to 'cull the herd.' PayPal please add 3%.
