Quick Read

Cayin RU7

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.

FiiO KA17

The KA17 is FiiO's $149.99 flagship dongle: dual ESS DACs feeding a THX AAA 78+ stage that scales from 300mW balanced on phone power to 650mW with an external supply in Desktop Mode. Approved reviews agree its pitch is unmatched drivability-per-dollar: Headfonics rates it one of the favorite dongles of its price segment for driving both IEMs and full-size headphones while staging well, and MajorHiFi's measurements confirm the power story. The recurring caveats are practical: it is large and power-hungry for a phone-fed dongle, and its clean, balanced tuning is more capable than characterful.

Strengths

  • Discrete 1-bit ladder architecture yields analog-like, natural timbre
  • Full-bodied, controlled bass with genuinely musical presentation
  • Double 2023 best-dongle awards from approved outlets

Weaknesses

  • Noticeable phone battery draw in DSD-heavy operation
  • Not the choice for strictly neutral, measurement-first listeners
  • $289.99 sits close to flagship delta-sigma dongle competition

Strengths

  • Desktop Mode unlocks 650mW balanced: genuine headphone-driving power
  • Clean, balanced sound with good staging for the class
  • Feature-dense: app EQ, gain modes, display, and dual outputs at $150

Weaknesses

  • Chunky for a dongle and thirsty on phone battery at high output
  • Neutral-clean tuning offers little romantic character
  • Desktop Mode requires carrying or plugging a second cable
