Priced around US$300 with single-ended 3.5mm output. Already placed an order, let see how this stack up against RU6, which is cheaper and also has balanced output.

Conclusion: Overpriced, roll-off treble, glitch, so AVOID, AVOID, AVOID.

P/S: July 27, 23. New firmware 1.06 finally fixed the glitch that causes extra noise in non-elcusive mode.

Looks great. I'm still single-ended at this stage, so don't mind lack of 4.4mm output.

Do we know the power output?
100mW @ 32ohm is the official number, though I won't put too much stock on any unverifiable manufacturer's claim.

It’d have to be quite a bit bigger to include 4.4. I like the size. Maybe there’s a 4.4 version in the future.

Cayin RU6: 65mm x 25.4mm x 13.7mm (138mW @ 32ohm)
Hiby FC6: 50mm x 22.4mm x 10.0mm (100mW @ 32ohm)

There is size increament given the additional 4.4mm jack and circuitry but not substantial I'd say.
I have not heard anyone complaining RU6 being bulky.
