What do you have feeding the magni? When I have Modi feeding Magni, I don't hear any noise until the volume is dangerously high, and I'm using Hd 280s that I've found to be fairly sensitive.
The whole reason I bought the M+M stack was because there was that my laptop sound card's headphone out was very annoyingly noisy, and the M+M stack is (to my ears) dead silent within safe volume ranges.
Now if I feed the Magni from the noisy output of my soundcard, the Magni does exactly what it should, and it sends the soundcard noise through to my headphones...
Now, if I turn software volume all the way down, and crank Magni to max, right as the knob reaches maximum volume, there is a noticeable amount of white noise and I can hear a local radio station if I hold my headphone cable just right. I'd be interested in a technical explanation as to how a maxxed out Magni can magically turn into a (poor quality) FM demodulator.
I have the modi feeding the magni and I'm using MrSpeakers Mad Dogs. It does not matter what my software (Win7) volume is set at, I start hearing white noise right after it passes 12 on the knob. For music, this usually isn't a problem as I almost never get near 12, but for videos and movies I routinely have to turn it past 12 and the noise gets annoying. Should I contact schiit?
