Cayin RU6

UNLIKE MANY RIVALS, the output of the RU6 is generated by two precision resistors to convert a digital binary number into an analogue output signal proportional to the value of the digital number. It’s fairly uncommon, especially in a form factor as compact as this, given there are 96 resistors in it.

The Cayin offers sample rate handling of 384kHz PCM and DSD256, which is combined with a discrete volume control so it is independent of the level of your source. It has a USB-C digital input to both 3.5 and 4.4mm balanced outs. There’s also high and low gain settings and you can use it in oversampling or non-oversamping mode.
