First off, this site is strongsauce.

I just bought Sens HD 595, which are low impedance headphones (~50 ohms).

In several threads, I've seen the terms "low impedance amps" and "high impedance amps". Am I supposed to get a low impedance amp for low impedance headphones? How do I know if an amp is tailored for low impedance headphones? I thought that a given amp could be used for either low or high impedance headphones. Or did I confuse myself by reading too many threads?

While we're at it, what are the best amps for Sens 595? I'm using the headphones for movies/games/music/pr0n mainly on the computer. I'm thinking i should get a soundcard with a built-in DAC and built-in headphone amplifier (e.g. ASUS Xonar Essence STX).

P.S. I was kidding about teh pr0n --> DAM SOUND LEAKAGE

You are overanalyzing things.

Most "good" amps have nearly 0 output impedance (considered "low") and work perfectly with any headphone. Some are limited by voltage output, some by current output and others are more "specialty" amps like a large variety of tube amps - they are more suited for low/high impedance because of output coupling schemes.

If you're going with solid-state, it generally should not be a problem.

There is no "best amp for x", need to know source, price, music taste, solid-state/tube/hybrid preference, portable/stationary and most importantly budget.
