The Qudelix 5k is a fantastic little DAC/Amp. It is very easy to operate through the IOS App, it is very small, light, and it sounds great – I am using it with 64 audio U12t. The bluetooth connection is great - I could leave my iPhone 10m away and still have no problem. The Qudelix EQ is quite elaborate and one could choose a setting that is designed for a particular headphone or IEM. After trying the EQ, i actually prefer to use it without, at least with the U12t. Headphonebar’s service is great as always. Highly recommended.
This little (and I do mean little) box is perfect for on-the-go listening with my phone, tablet, or laptop. Plenty of power to handle any IEM (does an admirable job with my Focal Clear as well). The Parametric EQ is where this guy shines and really helps separate it from the competition like the FiiO BTR5.
