FIIO K11 R2R

It offers a very organic, musical sound with very good technicalities, especially the imaging department. It is so good that it trades blows with more expensive DAC-AMP products such as the FIIO K7.
Not gonna lie, I feel bad for the owner of the OG K11, the K11 R2R feels like a step up from the OG K11. I genuinely thought this product was going to be a side grade of K11, only offering R2R organic tonality on a budget price, but NO, it also offers a step up even for the technicality part, all of it with a very accessible price.
