Just read the reviews! The tube input stage, with a single-ended mosfet output stage will deliver the cleanest and smoothest signal to even the most demanding headphones. When the music is this close to your ear, the tubes really help with respect to taking the edge off the upper midrange frequencies. They also create a deeper wider soundstage.
I am the original owner and the unit will be shipped in its original box with all original accessories.
***The unit is in (like new) perfect aesthetic condition.***
