Schiit Audio Mjolnir 2

Please also see my add for Sennheiser HD800S headphones.  I just couldn't get into headphones and found them uncomfortable and less enjoyable than speakers.  This amp, like my headphones was barely used.  I tried to improve the sound with some aftermarket NOS Philips Miniwatt SQ tubes that I ordered from Tube Depot (worth ~$375; see attached email photo of my online order confirmation).  Tubes were used lightly for about a month, so they have very few hours on them. Again, although the tubes and amp sound great, they just aren't for me.  I am selling my headphone gear to buy a new speaker amp. 
I will ship in the original box with the original foam packing spacers.
