Yeah but I wanted to hear some opinions. Is higher volume all the amp will offer or does the sound quality also improve? I don't really need a mic and "moderate volume" could still be good enough for me as I don't need the headphone to blast my ears off.
He says that one with a warm signature is recommended. Since I'm new to this idk what that means and which one offers that. >_>
I had my Q701 for a month or two with no amp and was perfectly happy with it. Then I got an amp and realized what everybody was talking about. It's not about volume. The amp changes the sound for the better...I don't understand the science behind it, but my ears were used to the sound without the amp and could hear the difference with the amp.
Is it necessary? No, absolutely not. However, when you read about how good the headphones are, people are reviewing them with an amp. If you aren't using an amp, you won't hear them to their full potential. If you're not hearing them to their full potential, you're kind of wasting money (IMHO).
Regarding the amp sound signature, I believe Fiio's tend to run on the warmer side, as well as the Schiit Vali. The Magni and the O2 tend to be more "analytical" and "cold". I'm sure someone will correct me if I'm wrong...
