Thanks for the info. Do they get a good amount of volume with the RU6? My current dongles are barely louder than using Bluetooth, and in the end the sound over Bluetooth seems fuller if less detailed than with those dongles.I have the Cayin RU6. Paired to the 5909 in passive mode, it sounds good. The character of the RU6 is preserved. I don’t know if you absolutely need to EQ the 5909 in passive mode. They sound very good as is paired to something like the RU6. Its not at all like the Sony or Bose that are absolute crap in passive mode.
To be honest, a lower distortion source (like the Mojo 2) sounds great with the 5909. With the onboard DSP EQ, you can drop the 20kHz treble down a notch if you feel the 5909 a little hot.
The Mojo 2 is very tempting... though a bit pricey and not as convenient.
