Great amp from a great seller. GLWTS

Price update for anyone watching this sale

Bought these a few months ago and put on a fresh set of Audeze leather pads. At the same time I picked up a good deal on a set of LCD-X's and I do not need both. Photos show a small scratch on the bamboo where the left gimbal stop jumped the track in shipping somehow. The sale comes with the...

I am selling of a recent acquisition. The amp runs perfectly, and looks the same as it did when I received it. I am only selling due to finding more engagement and fun in a DIY Sangaku that I also recently picked up and am in the process of upgrading. The Sangaku is a much better match for my...

Thank you for taking pictures. I was hoping to find some earlier this year, but failed and never thought about it again. I plan to do just as you suggested. Get one in house and swap out some parts. Did you trying running the amp without the DAC board installed? I would assume it works...
