FiiO K11 R2R DAC High-Resolution Compatible [Excellent Condition]

【Product Features】
This is FiiO's first model equipped with their in-house developed R2R DAC.
It features the smooth sound connection characteristic of R2R and a high musical texture.
The black color blends easily with your desk setup, and despite its compact size, it's a powerful unit that supports full balanced output.

【Product Condition】
This unit was purchased new from Amazon on January 30, 2026.
It has been used for approximately 1 month, and there are no scratches, dirt, or signs of use on the main unit.
It has been carefully stored in a non-smoking, pet-free environment.
The operation has been confirmed, and it is in a very clean, like-new condition (mint condition).
I purchased it expecting the natural sound unique to the R2R method.
However, the matching with my current main vacuum tube system was slightly different from the sound profile I had anticipated.
While I am very satisfied with the performance and quality of the device itself, I have decided to pass it on to someone who can cherish it more, considering the compatibility within my system configuration.
