FiiO K11 R2R - “Ready 2 Rumble!”

FiiO K11 R2R is an outstanding value product, providing a solid performance across the board in a very slim package and at reasonable price point. It's definitely here to disrupt the competition in sub-$200 all-in-one market. If you are looking for something with a different flavour from the slew of modern delta-sigma DACs in the market now, I can wholeheartedly recommend the K11 R2R.
