Amping can improve the SQ of even the most sensitive iems, it's not just about loudness, I know that people tend to think that an amp is being used only to get more juice to feed hard to drive cans.
In fact, it also acts as a frequency booster that reveals the full potential of a pair of headphones, IMO everything sound way more balanced, no more recessed lows,mids or highs depending on the chosen amplifier of course ☺
I agree with this. Sledge recommended I try the fiio e12a amp. It will not only power iems and low impedance headphones. It will make everything sound better.
I used to follow the same mindset that amping probably only gives more power. But the Amp i used made acoustic guitars, vocals sound more organic. Everything was improved in a good way. Even the instrument spacing.
I had to buy it and try out the amp for myself to understand.
Another thing that I find neat about the amp. I don't know if every amp has a volume knob. But I like how mine has it, it is very convenient plus only the incredibly expensive digital audio players have volume knobs on them.
