i think it was stated a few (maybe 30 pages back now haha) the faders decrease the sound quality some m100 users tried to use them on airplanes and it just doesn't work. my question is why do you want to listen so loud? an then have the faders dampen it? why not just turn it down?
i don't have the m100s but even with my monoprice 8323 i don't listen to above 50% on my iphone (which is loud for me anyway) and its like 40ohms with sensitivity 100 +/- 3 dB / 1mW (S.P. L at 1 k Hz)
to each their own but as a fellow head fi i would want to preserve your hearing for many years of audio nirvana ahead
Yes I agree that's why I would like to know what the loudest safe level is. I don't always listen to my music real loud, but for some songs I want to crank it up. I've just never tried the faders so I don't know what they do. On their description, to me it sounds like they only reduce the dangerous sounds. If they only make things less loud then yes there would be no point to me.
