FIIO K11 R2R

The K11 R2R is an affordable desktop kit, and arguably one of the cheapest R2R containing desktop devices presently. While there are no DAC filters, there is a more resolving OS mode and an analoguish laid-back NOS profile, so one is getting 2 tunings with a single purchase.
Other than the solid price-to-performance at its $100ish pricing, there is good power available with 3 gain settings, all housed within an attractive and compact profile, coupled with robust build. The volume steps are implemented well in terms of levels, and the K11 R2R runs cool during usage. It also has multiple inputs and outputs, and even a USB gaming mode for our gaming enthusiasts. I would have preferred additional buttons other than the sole volume knob that handles everything, but that is a nitpick.
