I'd recommend the Quicksilver Headphone amp, and it should fit nicely in your budget.... Excellent out of the box and even better with some judicious tube rolling.
ISO: Tube headphone amp for Planar headphones
Hello everyone. I recently purchased set of Audeze MM-100 headphones.
https://www.audeze.com/products/mm-100
At 18 ohms and 98 dB/1mW sensitivity they shouldn't be difficult to drive. I'm currently driving them with a beyerdynamic A20 Headphone Amplifier that I was using with a pair of beyerdynamic DT 770 PRO 250 cans.
While the new headphones sound okay with the A20, I can't help but feel that the current amp isn't driving the MM-100s to their potential. Granted, the MM-100 are analytical as they're meant to be studio monitors but I'm thinking that perhaps a decent tube amp would warm them up a bit.
So I'm looking for a tube headphone amplifier that will work well with the planars.
Budget is $800-1100. Thanks in advance!
Happy listening.
