STX - M-Stage - Philips Fidelio X1
What do you think? I will be buying the M-Stage a little while after the cans. I am just worried the sound might become ruined because the headphones have a 30 Impedance ..
The M-stage has a 5 ohm output impedance, giving you a damping factor of 6. That's a bit shy of the recommended 8, but 8 is just a guideline IMO. I wouldn't expect it to ruin the sound. However, the X1 is supposed to be easy to drive, so I don't really see why you want an amp in the first place. The STX could easily be enough amp for you. Definitely try the X1 with STX before you buy the M-stage.
Any particular reason you want the M-stage instead of a different amp?
