What is the best way to determine if you should buy an amp for your headphones? Is there a certain impedance that headphones should have before you consider an amp?

I would put that limit more around the 80-100 ohm range personally. If I run my 70ohm (and pretty high sensitivity) HD25's straight off my iPod, I have to turn it up louder than I am comfortable with to get decent volume out of most tracks, around the 70% mark if I remember correctly.
How much will a cheap amplifier like the Fiio E5 or E11 affect a pair of Sennheiser HD25s?
Is the difference that much to actually make me want to carry these around? It's not really the price I'm worried about, it's the portability factor here.
12. Is a headphone amp necessary for IEMs?
Some (though very few) IEMs do need an amp to shine, but not all. Less sensitive IEMs, such as Etymotic ER4S, often require an amp to function at its best. However, most IEM on the market do not need any amp to reach their full potential, even though amping may sometimes show an improvement in SQ.
The easiest way to identify which IEMs need amping is to look at the specifications. The general guideline is: IEMs which have less than 50 ohms impedance and more than 98 dB on sensitivity most certainly don't require an amp to sound their best.

Any amp has different style, so the problem is how can I listen various music via one amp...However I don't want to buy 3 or 4 amps for different music....
