Yes and not, this move (V2 version 6 months after launch of HEX and 1 year after HEK) would be correct if they didn't do the beta testers program.
This is the product that the beta testers wanted, so this "V2 versions" should've been released one year ago, that's the purpose of a beta testers program, to know what your customers want.
Is normal to improve products, Sennheiser launched HD800S six years after and without public beta testers program...what Hifiman did is reserve the opinions of the beta testers to save the R&D for a V2 version, and of course to make more money of that second revision, not a very honest way to do things.
Focal was the wisest company, I'm sure they hired someone to read Head-fi one entire year, recollected info, and they said: OK, a headphone like this and another like that, and...boom, totally disrupted everything. Oh, and very wise pricing decisions, they have a nice opportunity to collect feedback of the 1kusd and the 4kusd headphone and release a 2kusd headphone that suits another part of the market...that's how you do things right, what Hifiman is doing is laughing at customer's face.
