Headphoneus Supremus
I can't comment on the PM-3's but I am running Bowers and Wilkins P7s with my Fiio and they sound great straight out, but even better through the E12A Mont Blanc.
If you get a chance to try them out, they are lovely headphones and so well made, just thought I would throw my 2c behind them
Oh no, I don't know what to do ! ?
