Hi, newbie here. I found that some headphones need an amp to get most of out it cause they have high impedance. Just wondering from what impedance and on would you need an amp?
Also is a Fiio E7 enough to drive a pair of headphones at 300 ohms?
Would it be a waste of money to spend $100 for an amp to use it on a pair of headphones at 32 ohms that cost around $250?
