I should have mentioned in my previous post that I own an ARC Ref 6SE, and that I toured the ARC factory last summer (I live nearby). The i/50s are built by the same folks in the same building as everything else. They were building a lot of them, palettes and palettes marked for shipping all over the world. They even have their own paint booth for them in-house (cerakote I believe). They sweat the details at ARC, the i/50 is no exception.
