Hey Guys,
I have a pair of Sennheiser HD650s that I picked up about a year ago. I've been using them on my computer with a Nuforce uDAC-2 running into a LittleDot MK III amp. They worked great for awhile, but now I'm having some confusing problems.
1) The left speaker was buzzing, and mostly playing only the lows, so I took the pads off to clean out any stray hairs/dust. I found nothing, and when I plugged it back it, it worked.
2) Moments later, the right speaker started buzzing (same problem/sound), so I did the same. I plugged it back in, and it still buzzed.
3) I plugged the headphones directly into an iPod, and cranked the volume - both speakers worked flawlessly.
4) When I plugged back into my computer/amp, the headphones worked great for about 2 seconds, then the right speaker started buzzing again.
5) I've been able to repeat 3 and 4 a couple times.
The LittleDot amp puts out 350mW of power at 300ohms (same resistance as the Senn 650s) - any idea if/why the amp may be causing this?
Thanks
