Hi, saying “RU6 does have a more natural warmth and body while W2 tilts the scale in the opposi So for a stereo 24 Bit R-2R decoder, RU6 features 96 units of resistors for life-like audio reproduction. The proposed solution has come in the form of a resurgence of R-2R DACs that were superseded by modern delta-sigma solutions decades ago.

While owing to the analog tonality of all R2R tech devices - this may not be the most resolving one but the Oversampling mode somehow takes care of it quite well and the resolution is just great.

The RU6 from Cayin is a portable USB DAC and headphone amplifier, allowing you to connect to your devices for high-quality, audiophile-grade sound wherever you are. U18t does present you with a more forward and more revealing tonality, but in pair up with RU6 it sounds less harsh and a lot less fatigue in comparison to some other sources. So, it will depend on if you are pairing with warmer or brighter tuned IEMs, the synergy will be different depending on tonality of the source. Digital filter-less, no post-processing, optimised in time domain, low phase distortion and jitter, no ringing artefact. Oriveti's new flagship hybrid offers a unique sound with Harman inspiration augmented by a big sub-bass focus.

To me, the biggest appeal of RU6, it was designed with a legacy Rail to Rail Array Resistors audio processing which clearly revealed the intent by Cayin on why they choose it - True Analogue sound. 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. If you think that was challenging to pack into a pocket friendly DAP or a small modular card, imagine getting it all inside of a small usb DAC/amp dongle.The signal path is single ended as the audio signal goes through R-2R DAC, Low Pass filter, Resistor Array volume control, Line Driver, and Phone Amplifier with gain control. There is a small pinhole vent ahead of the 2-pin connectors, not sure if this is actually for tuning or letting the sub-bass drivers breathe or pressure adjustment. Included were a short, properly shielded usb-c to usb-c OTG interconnect cable and a cool usb-c to usb-A adapter to use RU6 with devices that have standard usb port. One of the achievements that surprised me most is that RU-6 drives successfully not only demanding iems but also demanding headphones - it drivers perfectly the Z1R iem but also the Z7M2 headphones, it also drives very well the P1 but also even the T60rp (for the headphones I used the 4.

The superb performance of the Cayin RU6 makes it an easy recommendation to anyone who is looking for a dongle with R2R capabilities. The new Andro features Knowles' new dual diaphragm BA drivers and employs a more comfortable shell design. RU6 was connected to my Galaxy phone with volume set at the max (on the phone), and I was using HibyMusic app. output of RU6, and was able to regain body in mids of Empyrean and can hear now a deeper sub-bass with more weight in mid-bass. Following a popular release of R01 which brought their 2-year-old N6ii back into the spotlight, to an unexpected surprise of many audiophiles, Cayin scaled down the R01 design into a small standalone usb dongle with a power to transform your smartphone, tablet, laptop, or another DAP into a hi-res audio player with discrete resistor R-2R Ladder DAC.The leather case for extra protection and the lightning cable for iOS users can be separately purchased. While based on the specs mW stats this is slightly less powerful than the W2 - but in real life scenario I found this to be quite powerful and can easily power even power hungry IEMs. On the front of RU6 you will find 1” OLED screen display to view playback info, such as sampling rate, volume level, gain setting, and NOS or OS oversampling mode. Tested with my listening gears, what I am hearing is super transparent resolution throughout the dynamic range.

Instruments are quite precisely imaged and you can pick from the mix easily where the instrument radiates from. PROS: R-2R discrete resistor DAC design (the first R-2R portable usb dac dongle), natural analog tonality with a resolving sound, NOS implementation, Resistor Array volume control, 3.

Hello, sorry for my ignorance (I'm kind of new to the hobby) I own MEST MKI coupled with a FiiO BTR5 - Does the Cayin RU6 offer bluetooth capabilities? balanced jack of the RU6, switched on NOS mode, and was playing music out of Roon from my desktop PC. With sensitive IEMs such as the Campfire Audio Solaris 2020, background noise wasn't an issue for me but I'm not the pickiest about this.
