If anyone thinks the HD800 is 'soulless'.. they haven't listened to it through a BH Crack.. with the Raytheon VT-231 tube. It's heavenly. As far as full sized headphones go.. there's nothing.. NOTHING else.. that I want to listen with (under $1500). It possesses the clarity, speed, transparency, and extension of what you'd expect from an excellent, neutral sold state amp amp.. but provides the rich, natural, vibrant presentation of a great tube. I've rolled a number of 12AU7s and 12BH7s.. I've yet to find one that sounds as phenomenal as the the Raytheon VT-231 does.
..and it's absolutely badass with rock/metal.
..now, back to our regularly scheduled knob-twiddling.
