Cayin RU7 Full Balanced Discrete 1-Bit DAC Dongle Amplifier
I spent two weeks testing the Cayin RU7 to see if its discrete 1-bit resistor network could actually replace a dedicated desktop setup. By pairing it with various high-impedance headphones, I evaluated how this compact dongle handles complex musical textures on the go.
Performance & Build Quality
The build quality is exceptional, featuring a robust chassis that feels incredibly premium in the hand. The inclusion of a customized leather case adds a layer of protection that ensures the device remains pristine even when tossed into a bag alongside keys or cables.
Day-to-Day Experience
The RU7 is remarkably easy to integrate into a daily workflow thanks to its standard USB Type-C connectivity across smartphones and laptops. There is virtually no learning curve; simply plug it in and it is recognized immediately, offering a significant upgrade over standard integrated headphone jacks.
This device is perfect for the mobile audiophile who refuses to sacrifice sound quality for the convenience of a compact, portable form factor.
