The RU6 has a rectangular shaped body which is bulkier and heavier than the usual D/S USB DAC/Amps like the EarMen Sparrow. Canpur is showing that they have come to do serious battle in the space, and these CP32E are no exception! The sound stage is wide, especially in depth; the layering is impressive; the separation between instruments is solid and I even find that RU-6 has 3D presentation.

With NOS mode, you get the unadulterated input signal while in OS mode, the digital audio bridge up samples digital audio data to 384kHz using digital filters. The more effective solution with R-2R design is to keep the incoming bit-stream at full volume and then implement a high-quality analog volume control after the R-2R DAC circuit. The RU6 is prone to picking EMI interference from a phone that causes background noise which can range from a faint hiss to a louder humming especially when using more sensitive earphones. Cayin therefore recommends a music player app for the smart device that supports Bit Perfect USB and thus bypasses the level control of the source device. In this section of my review, I will go over how various earphones and headphones pair up with RU6, and mention volume setting (v) and gain setting (High Gain or Low Gain).This architecture minimises power drain from the mobile source allowing you to enjoy music without the need to worry about battery drain.

And when I say discrete solution, I’m talking about dozens of small resistors forming a discrete R-2R Ladder DAC. The sound has a natural smoother tonality, good bass extension with a textured sub-bass rumble, natural detailed mids, a little peaky lower treble but nothing too harsh, treble has a decent airy extension; soundstage is wide; background is black except for a very mild waterfall hissing. That means you can plug it into your laptop, iPad, or phone as well as DAPs and enjoy R-2R decoding. According to Cayin, that presented a challenge of picking the volume control with higher precision, lower noise, and less power consumption.Audio U18t (v28, HG) – slightly mid-forward signature due to more neutral bass quantity of U18t, still with a good extension and punch, just closer to neutral in quantity.

The FiiO KA3 might have the technicalities edge for electronic music and such genres or be better suited for ultimate detail and clarity lovers but the RU6 with its more natural timbre and grander soundstage is the obvious choice for classical and acoustic music. That surely improved the sound with deeper sub-bass and beefier mid-bass, more body in mids, and overall, more natural balanced sound. Cayin is using only resistors that can deliver extreme precision and remain stable during temperature changes. The RU6 isn’t a device that photographs especially well but exudes a classy, high-quality impression in person. Being one of the most powerful dongles on the market and boasting a unique DAC design, many question marks are raised regarding power consumption.

Voices and acoustic instruments are heard organic with natural overtones and plenty of harmonic wealth, a wonderful combination which leads to an engaging and authentic listening experience.

You can use the mode button to enter the menu and configure gain settings, NOS/OS mode and screen timeout. Switching to the OS mode doesn't induce extra digitus but the sound somewhat loses some of its analogue, organic magic. I've been gravitating towards this dongle over the iBasso DX240 lately too, but part of it is due to a new experience, but it's also a nice intoxicating blend of soulfulness and low-fatigue that provides a long lasting listen. It reaches deep but neither very low end or mid bass are pronounced - just detailed and right sounding.Not because they had many things in common - but mostly because people asked for a dongle shoot-out and so here it is from me. Another thing to note, RU6 doesn’t have a fully balanced design since there is no room for all the components.
