Saw this headphone amp for 99$ on Super Best Audio Friends. Its a balanced amp and has very low distortion. Its 99$ for the PCB and parts to solder yourself. Thing is the Chassis costs 200$. How can that be twice the price of the very amp itself lol.
Anyway this looks like a great option for a low distortion balanced amp for 99$ if you want to put together yourself. maybe i could get a different chassis for it thats not so expensive.
