I use it with Dali Oberon 3 and a Fosi audio ZD3 DAC (XLR connection) after replaced a Fosi V3 stereo (RCA) and the improvement is surely noticeable with a clean sound, a little better bass, no hiss noise in silence from tweeters (extremely low noise -inaudible). The volume bypass and standby mode are its main advantages to get & with quality input/outputs connectors. I wouldn't expect and ask something more for the cost it has. Many Thanks to Audiophonics for the opportunity to offer it in stock and for the quick/safe shipping
