oh my gosh this small amp has 4 freakin threads.. I gleaned quite a bit from the other impression thread but have no idea which on to subscribe to. For those of you who have a pulse infinity, how much of a step up is this from the balanced headphone out of the infinity? I only ask because one individual felt the amp on the infinity was better. I am very doubtful of that comment for two reasons.. the headphone out of the infinity balanced sounds thin, slightly bright, and definitely not my cup of tea. From what I understand the pulse infinity dac is actually not bright so I am hoping to have better results from this as a stand alone amp with the infinity. I just left the thx00 drop and think I made the right choice by purchasing this amp instead, I can always pick up a used txh00. If this doesn't work for me then I will save up for an eddie current black widow.
