*The FC4 features an MQA renderer now, and it is going to include MQA full decoding technology in the next few months.

The smartphone must be using apps supporting bit-perfect and MQA (e.g. HiByMusic, TIDAL), in order for MQA unfolding to occur with the HiBy FC4 connected via USB.

HiBy FC4

Was also considering iBasso dc06 but decided to go with the FC4. iBasso was a little expensive and lacking any physical keys to control the volume, though iBasso has an app which allows to control the volume but you need to access the phone all the time to control it. FC4 on the other hand has physical volume buttons which gives you additional control on volume. I was able to drive the Sundara at around 80% of volume and pairing it with the Timeless was superb. Overall a great buy and speedy delivery as well.
