As detailed in the blog posts,here, and here.
I got it for $50, made some mods that drastically improved the sound, but I'm drowning in headphone amps around here and it frankly is not going to compete against my reference so I should like to pass it along to a new owner.
It's a sweet little amp, linear, split supply, a "proper" circuit, no virtual grounds and such nonsense. NJM4556 op amp (like Grado RA-1). The sound is honest and easy on the ears.
Looking to sell for $40 including shipping. I'm sick of ebay's shenanigans, this is a old-school "pm me if interested" offer.
