The K21 includes just the Player engine from the K50, to play to the USB input on a customer’s DAC. The K21 can also run Server apps, but is only medium-powered so is not suitable for very large libraries (>8TB) or heavy DSP functions. The K21 can have one SSD added by the customer (up to 8TB). The customer can upgrade later by adding a K41, improving Server app responsiveness and significantly enhancing sound quality.
