To achieve 24bit R-2R decoding, Cayin need 48 pieces of resistors (23xR and 25x2R) for one channel, or 96 pieces of high precision resistors for stereo. 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. However, they often ended up being too clean sounding that they lacked musicality and some even lacking realism altogether. Cayin has implemented this using a USB Audio Bridge that receives digital data and sends it to the Digital Audio Bridge where DSD is converted to PCM if required.

The RU6 can pick up a bit of EMI from a phone and cause some faint hiss in the background which is audible on more sensitive IEMs. I don’t have iPhone but measured current from lightning connector of ipod touch with RU6 connected, and it was drawing 130mA as well. The Oversampling DA mode – again according to Cayin – will offer noticeable improvement on details and frequency extension. The Cayin comes standard with a USB-C to USB-C cable, along with a USB-A adapter, but for iPhone users, a lightning cable can be purchased separately.It is the first ever dongle to feature Discrete 24 bit R2R capabilities and have some very nifty new features built-into it.

The Cayin RU6 offers a different “analog” approach in the world of highly integrated delta-sigma chipset packages and DSP filters. The highs seem like there may be a spike or peak somewhere in the upper mids or treble, but not in a painful way. Sometimes the faintest hissing was still present even with host devices without cellular antenna but it must be related to the host device power supply. I did not have any issues with getting audio working with any of the devices, however with the Chromebook, I did get the occasional stutter and pop when I was loading a webpage or doing other background activity that was may have interfered with the audio stream.It subverts what you may expect, delivering powerful bass but also an energetic and detailed top end. 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?
