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.

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.Still for a device featuring an R-2R network and resistor array volume control, it is quite compact and lightweight, not that larger than the FiiO KA3.

It is warm and laid-back, and does a great job of eliminating digital glare that I find most noticeable in the upper midrange. Bass could have benefitted from a little boost, but overall, the bass has a deep extension, nice fast punch, mids have more neutral lower mids, clear detailed upper mids and vocals, and detailed crunchy treble with a nice airy sparkle. One that preserves a tube-like musical quality but with much finer volume control and packed within a favorable form factor. The RU6 is plug'n play compatible with all USB-OTG devices (iOS and Android), Mac OS, Windows PC through the available driver and it can also be connected to Digital audio players that support USB out. By the time Cayin completed the R01 Audio Motherboard for the N6ii DAP, they noticed that the R-2R resistor ladder network could be implemented as a low power consumption DAC circuit that offers outstanding audio performance.Despite receiving the dongle free of cost, I will attempt to be as objective as possible in my evaluation. A longer USB cable may be a fast rescue or you may try to stick some copper foil at the back of the RU6 inside the casing. 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. Cayin states the playback will become very musical with a natural, organic and coherent presentation. Safeguard signal integrity, make sure the noise from reference clock and DSP will not bleed into the amplification circuit.
