FIIO'S E11K KILIMANJARO 2
FiiO has done a great job in my opinion. While users who have listened to more expensive setups will probably not be wowed by the E11K, it’s hard not to be impressed by the good SQ at the extremely reasonable price point.
Fiio is a Chinese maker of audio equipment that has become well known for offering good gear at highly competitive prices.
FIIO E11K: THE NEW BUDGET KING
I’m glad I turned out to like the new E11K, my ears have been spoiled with higher end gear a lot but if you can enjoy your musical collection and headphones with a $60 amp, you just know Fiio did it right. Again.
Everyone loves Fiio. Just look at their Facebook or check Head-Fi. The Chinese company is known for its budget friendly setups and they are genuinely nice people who really listen to the community. Lately they have even been targeting the high resolution market with their X5 DAP. Today however we take a look at the updated version of their successful E11 amp.
