Do they make the sound quality better?
I really don't know much about them and I just heard about them this week when I was looking through this website and I am just confused about what they do.
Thank you for your help!
Well a better amp is improved, higher quality circuitry too so it does help the SQ. The difference isn't gigantic but it is definitely there. Aside from allowing the use of higher impedance headphones it bypasses the music player's/phone's internal circuity and its substandard headphone jack. The amp will also allow greater clarity at higher volumes.
You do not need to know how many Ohms go with an amp. A wide range of headphones are 32 Ohms or less, with pairs like these you can drive them with any of the cheaper amps absolutely no problem. Headphones with a higher impedance will demand more powerful, expensive amps. The Ray Samuels line, ALO Audio's line of amps, and several other brands will all suffice, it just takes doing some homework. Some amps sound different than others, some are far smaller, it just depends on personal preference to a degree. There is no concrete "best portable amp" despite what people argue. There is a litany of options on the markets and what one is best for you will likely depend on price, power, and size of the amp itself.
Hope that helps. Happy to help! :)
