I finally ordered my Ultrasone PRO 550's today and I really cannot wait to get them.
However, people on OCN have been telling me different things about whether or not I will need an amp or not to drive these headphones. I am a novice when it comes to headphones so I wouldn't know either. All I know is that the headphones have 64 Ohm impedance.
So would I need an amp to drive these? If so, would my current Fiio e5 do the trick? If not, are there any good headphone amps under $50 that I could use?
If I don't need an amp, I would prefer not to buy one to not waste money of course.
The headphones will be used 80% of the time with my Titanium HD sound card, and the other 20% of the time with my laptop or phone.
