I live in a Schiitty neighborhood
Turns out that Schiit audio is just across town from me. I am going to stop by their showroom to demo their headphone amps when the Sennheiser 6XX's come. By then I should be able to save for something better than a $100 and something dollar amp. Does anyone have any experience with their more expensive amps that would be good with the above-mentioned cans? They say the have a bunch of demo stuff on hand so I can go anytime to get some ideas.
