Yes, got the zodiac this week, and listened for 10hrs from DX220+AMP8Ex-FE. And this a fantastic IEM to tell you! My impressions are very much in-line with
@davidmolliere
I too ended up using all the switches up, but even with the 020 mode, it sounds so balanced with a very lush mids which i wanted. I was looking for a midrange specific IEM and this is it for me.
With all switches up, the sounds is very full bodied, the sub-bass is quite strong on these, the mids are forward but still retain the timbre and the lushness, so vocal based songs are very nice to hear on these.
Treble is not harsh here at all, its present and quite clear, but not airy.
Soundstage and depth isn't the biggest here with the stock cable, but pairing with Eletech's Prudence made the soundstage bigger and gave the overall signature more air. But i went back to the stock cable since i loved the full bodied sound.
Love this IEM quite a bit, hence decided i am good for 5-6 months or more, so going underground for a while and saving for a flagship that i'll buy then. If you need specific or want me to test something, drop me a PM
