That's quite a gamble! (not AE standard shipping, but buying this fairly expensive unknown IEM)Here comes a madlad.
Since GS audio only takes Aliexpress standard shipping (and it will take like 1-2month), and offers no other options, I placed the order for ST10. (430+10shipping+US sales tax, totaled $470).
-A custom built ones are not returnable, so if something happens, it’s a risk.
-AE standard shipping (kinda worried to ship expensive IEM over this shipping channel…)
We will see…
I'm looking forward for you impressions and I'd really like a short comparison with your SA6!
