Big HeadAmp

Recommended Posts

it's just...another diy headphone amp project (again) :shifty:

 

This amp very well compliment the MPA2.5; not very much of details, not very powerful, not very fast sounding, but....it's wonderful for woody, and supposedly, the akg k70x. ppl said it's sounds like tube amp but in fact it's solid state amp :lol:

PSU: Copper Taped R-Core + Precision Single Rail Voltage Regulator
