The initial listen was just a tad harsh and bright in the upper midrange, while the low end was warm and thick, with a smooth and relaxed treble. the only cable I have with these 470ohm cans, and raised the volume to 74 since these are harder to drive. I find the tonality very much similar to the Chord Mojo, with a warm and intimate presentation, and overall smoothness that sounds mature and inviting. Hi, saying “RU6 does have a more natural warmth and body while W2 tilts the scale in the opposite direction while being more transparent and more revealing” did you use NOS or OS mode on RU6 while comparing?

I was trying to resist the temptation to try this, but curiosity got the better of me, and I had to see how this little engineering and packaging wonder sounded. My two top pairs - IER-Z1R and UM Mest - so perfect: well controlled bass, improved vocals , enlarged sound stage and 3D.

The FiiO KA3 is one of the best examples of a well implemented D/S USB dongle with the least possible digital imprint but the RU6 is a step above with a more organic and natural texture.

As for the advantage of R-2R, unlike delta-sigma dac chipsets, it does not require a digital noise filter nor a feedback loop design, so it is born to be very quiet in the background and at the same time very unaltered in tone. The very expressive midrange on RU6 performs really well with indie rock, slow jazz, old pop songs, and house music. It comes packed with single Cirrus Logic CS43131 DAC chip and good build and some nifty features including BT and the volume dial. It subverts what you may expect, delivering powerful bass but also an energetic and detailed top end.Actually, dongles have been making a big comeback lately, feature-packed with SE and BAL outputs, control buttons, and a display to access the config of the device without a need for an app, everything you will find in this latest Cayin release.

Most USB dongle DACs will rely on the volume control of your mobile phone to control the volume of the headphone output but this is not a viable solution for the Cayin RU6.

The effect is more pronounced when streaming and not as severe when playing music from local files but still there.
