Cayin RU7
Universal Summary
The RU7 brought Cayin's discrete 1-bit resistor-ladder DAC concept down to dongle size at $289.99, decoding up to DSD256 natively with everything internally converted to DSD. Both major approved outlets gave it their 2023 best-dongle award: Headfonia hears a neutral-leaning but full-bodied, powerfully controlled presentation that stays musical and engaging, and Headfonics rates it the best of Cayin's dongle line in both agreeable timbre and technical prowess. The consensus flags analog-like smoothness and naturalness as the signature; the tradeoffs are moderate battery draw, a warm-of-clinical character that measurement purists may not want, and pricing near very strong delta-sigma rivals.
