I have been an audiophile for about fifty years, but have only been into headphones for maybe two years. My idea of headphones came from the 60s when all the sound imaged in the center of your head. Today I find that in many way headphones are a more intimate and rewarding experience than speakers. To that end, I have found the Darkvoice 336se to be by far the best of the four headphone amps that I have owned thus far. While I prefer the tube sound, the small, little bitty amps with tubes sticking out do no create and expectation of good sound...
