The device is good. Compared with the Home Spot () but the Philips adapter is much more expensive and worse in the equipment. I AEA2500 / 12 compared to Homespot and Phillips right on my Onkyo amplifier. I could not hear a difference with the best intentions. My Onkyo amplifier outputs sound from the Pure-Function again unadulterated. It was to hear no difference, even in classical music is not. The Philips also has no USB power adapter as opposed to home spot, which is the biggest criticism. The Homespot can I operate on USB from Onky amplifier, the Philips contrast needs its own power supply.
