I have Cyan2, A26 (sold), R26, and X26III. The only way I can recommend Cyan2 is together with HQ Player to upsample. And the best it can sound is when upsampled to DSD with the HQ Player DAC correction pipeline enabled. which is slightly out of reach for me with my gaming laptop since this setting is too processor intensive.
With no HQ Player, I would prefer the R26 Hands down. The Cyan is NOS only. If you listen mainly to small combo audiophile recordings, the Cyan can sound very pleasantly liquid and fleshed out. I listen to rock with deep and wide studio effects and the one word that constantly popped up when switching back from the R26 to the Cyan2 was "boring". And the R26 has the deepest, widest layering of any of my DACs with the optimal setup of HQ Player to 768/ 23 via LAN NAA and a cheap external clock.
Now that I have the newest Gustard X26III, I find it to be the best at incisive see through detail, and slam. The R26 still holds a slight advantage in sound stage depth but now sounds slightly "hazy" compared to the X26III's crystal clean presentation.
If you can get a used R26 for $1000, it is a solid deal. Otherwise, if you want more speed and dynamics than the Cyan2 and don't have a cutting edge gaming tower to feed it HQ Player, I am recommending the X26III.
