Cayin RU9 Tube/Solid-state DAC Amplifier

Sounds awesome, has great power and life span features such as DC mode, has trash LDAC range. Can't fault the bt function being mid. For all I know it could be my phone's fault. What a beautiful unit

Amazing!

This unit has some great features and an amazing tonality. It has power to drive full-sized headphones and sensitive IEMs. I love the MagSafe capability as well. The only downside for me is the battery life. The 4-5 hour claim is generous as I don’t quite get that. But, the hyper mode via DC ups the tonal game considerably. The RU9 is my favorite DAC amp I own so far and I have been collecting for a while. Very happy with the purchase and you will be too.

Fantastic OTG Device

This is a perfect travel device and awesome in "desktop" mode in the office. It has a surprisingly tubey sound and can power my 300ohm ZMF headphones while being dead silent with IEMs. MusicTeck was easy to work with, shipping was fast and secure
