Looking at the specs though it does from 20-600ohm if I've not misinterpreted them?
Can anyone confirm they're successfully using 32ohm headphones with this amp?
I've used mine with 250ohm modified Sony's, 16 ohm IEMs, and a bunch of stuff in between. Now, it definitely works better with higher impedance headphones, but it will work with 32ohm headphones. It just wont be driven to it's full potential. It sounds best, to me, with a 150ish ohm headphone. However, my Grado SR60's sound nice with it as well, and they are 32 ohms.
