Pros: Excellent warm sound, Powerful, Detailed, Transparent, Black silent background, Form factor and design
Cons: I don't know why they didn't design the amp with an on/off switch, Slight interference at lowest volume
There were many amps in 250$ range to choose from, but I liked iCAN's unique design and the shape. I don't have many headphones to do a comparison. I'm not a big fan of bass boost and 3D, but sometimes I do use bass boost on one dot position (by the way, I'd like the one dot setting to come after the direct setting).
The bass boost works perfectly and doesn't bleed to mid range (in one dot setting). The 3D holographic effect works fine with some tracks, you have to figure out on your own.
I'm very much pleased with this amp, if you are looking for an amp in 250$ range, do consider the iCAN micro, because it's very powerful and very smooth sounding amp.
