Hi,
 
I have for a while an MF M1HPA amp. I bought it to be used with DENON D7000. Recently I connected at the same time two headphones, DENON D7000 and SENNHEISER HD 555 and noticed some changes in the sound, bass in both headphones is boomy. When I'm using just one pair of headphones everything is ok. Who had the chance to use this amp with 2 headphones at the same time did you noticed same issues ? Thank you.

That's easy. With 2 pair of headphones you getting half the power and thus less control in bass.

Thank you Dexon for reply. I was thinking about this but some people are saying that M1HPA is powerfull enough to drive two pairs of Audeze LCD2. And as I know D7000 and HD555 are not so hard to drive ... but who knows. Anyway till now I can't find another explanation than lack of power or defective amp.
