cayin ru9 review ProsCons...
The Cayin RU9 takes a legacy form factor, mixes it with modern audiophile needs to create a DAC/Amp with impressive, yet very 'tweakable' sound, excellent power output, and all inside a low-profile yet extremely sturdy design.
Pros
- Lots of tone controls and performance options
- DC mode capable of driving demanding headphones
- Internal battery has a significant advantage over non-battery dongles.
Cons
- Too be big to be classed as a dongle and makes its presence known when stacked with a phone.
