O2 Headphone Amp (teaser)

Recommended Posts

Just got mine and great, I'm only wondering if I should upgrade NJM2068D amp chip for NE5532AP, been told at standard gains it has lower distortion but since I'm not at all an electro technician, need feed back. I'm basically using the amp with Ultrazone Pro 900. Since I also have two cMoy v2.03, I'm thinking of upgrading actual chip on one with NE5532AP if it fits and sound...better?
