I am using the Senn 600s with Headroom Max. I like the processing circuit which removes some of the "music in the middle of the head" feeling headphones are sometimes prone to. Should be just a little under your limit used.
Headphone Amp. for Sennheiser HD 580 headphones...
Any recommendations for a GOOD headphone amplifier? I have an Audio Research LS 15 pre amp. and would like to be able to listen to the headphones at night. CD player is Naim CD5. I just noticed an add for an Earmax headphone amplifier and it looked really nice.(Sold) Will set the price range up to $800. Unit could be SS or tube. thank you for your suggestions. Richard.....
