Verdict: The Gustard R26 and iFi iCAN Signature serve fundamentally different roles—one is a pure R-2R DAC and the other a hybrid headphone amplifier—so direct comparison is limited. The R26 provides superior measured linearity and natural timbre according to user reports on Head-Fi and r/audiophile, while the iCAN Signature offers 7500 mW output and tube warmth that the R26 lacks entirely. Pairing both together is the logical use case rather than choosing one over the other.
Winner: Neither - different categories
Gustard R26: 7.5/10

Our pick: Neither - different categories. That said, Gustard R26 still wins on natural r-2r timbre with wide soundstage — consider it if that single trade matters most for your use.
