Hey,

Could you please direct me onto some blueprints of the amp that would be the best for my 80-Ohm headphones? Any help would be appreciated

Mine's built from Rockhopper Audio but you can find the blueprints for a mini^3 from AMB Labs official site

The Mini³ Portable Stereo Headphone Amplifier

Sweet sweet amp for the price, its a little big for out of the house portable IMO but its great for around the house DAP listening with the DT770s, tightens up and greatly refines the bass
