The Pasi, made by the Great northern sound company, a serious upgrade for all digial playback components. Just plug it in between the CD/Dac/dvd/Sacd and the pre/intergreated amplifier exteremely simple but very effective. A seriously more open and detailed sound, great 'body' to image and a more flowing and natural sounds emerges too. Bomb proof build, takes either Single ended or XLR balanced also great way to get a balanced output.
