Our Verdict
I spent the last two weeks testing the Cayin RU7 to see if its discrete 1-bit architecture could truly replace a desktop setup for on-the-go listening. This compact dongle promises a level of refinement rarely found in such a small form factor, and it certainly changes how you experience your digital library.
Performance & Build Quality
The device feels incredibly robust, featuring a solid chassis that balances weight and durability perfectly. The inclusion of a high-quality leather case adds a layer of protection that ensures it stays pristine while bouncing around in a bag or pocket.
Day-to-Day Experience
Integrating the RU7 into my daily commute was seamless thanks to its standard USB Type-C connectivity. There is virtually no learning curve; it acts as a plug-and-play solution that instantly elevates the output of any mobile device I paired it with.
This is the ideal companion for mobile audiophiles who want to experience the specific, natural character of a discrete 1-bit DAC without being tethered to a desk.
Final Thoughts
The Cayin RU7 stands out as a top-tier performer in the competitive dongle market, earning a well-deserved 4.75 out of 5 rating. At $499.00, it remains a premium choice, but the sonic performance it delivers is well worth the cost for those chasing high-end audio quality.
