But after experiencing Perfidus, I realised the headamp could present such a wide sound stage and a three dimensional feeling of the recordings. It has lots of details in the low, mid and high range, a sweet enough mid range, accurate positioning, and yet and the same time sounds musical, and I believe it can greatly improve the musical performance of a headphone set up. If you are looking for a headphone amp, I would strongly suggest you audit the Perfidus! http://www.fuwen.net...fidious-headamp Edited February 11, 2016 by fuwen Share this post Link to post Share on other sites
