Really enjoying my ZD3 and ZA3 combo.

I purchased the ZA3, ZD3, and Box X5 for a new stereo build that is going in our living room along with two POLK ES20 bookshelf speakers and a Fluance rt82 turntable. I connected the ZA3 and ZD3 with XLR and attached and ran an HDMI ARC from our TV to the unit. Everything else is RCA/speaker wires... What's awesome is that when running audio through the TV, everything can be handled by the TV remote! This makes for an easy streaming system. It even handles power on and off... I wasn't sure what to expect with the HDMI ARC, but it has been the most used feature of the ZD3.

All in all, for a small bookshelf system, I really think Fosi has done a great job here. I've been watching the company grow for the last ~5 years and really happy with their gear so far. Only nit pick... The power supplies feel a bit lacking in quality. I'm sure they're fine, but the cords feel very thin and flimsy.

Sound quality is quite good for the price but I have some strange issues regarding volume controls and connectivity. Sometimes volume “sticks” and don’t change when knob is turned. Sometimes when the device is turned on by HDMI Arc input it makes loud static noise for couple seconds.
