Phones: AKG Q-701
DAC/Amp: Nuforce Icon HDP
Aprox 100 hours of burn in with music + white/pink noise
Short but sweet background:
Have a small studio for music production with hard/soft synths and have noticed that certain notes and frequencies seem to distort my Q-701's but not my Yamaha monitors which run on a focusrite DAC. Nothing distorts in the low end but once I start to play notes in the higher frequencies I get distortion BUT if I go 1 note higher the distortion ceases. I don't play particularly loud and don't over emphasize the bass.
Could I have blown one of the drivers? But then why wouldn't it sound distorted upon the notes prior to and after the one that seem to cause the distortion?
Appreciate you taking the time to read this and hopefully respond.
