What I'd love to see is just a clearer stripped down line-up, so you can focus resources on fewer products (and it make it easier for all of us to choose which to go for). There seems to be so many iFi products coming out and a lot of confusion amongst people about which to buy, or even in the microDSD signature thread people holding off because they thought with the Diablo around the corner they should just wait. So I wonder how many will just hold off from current or future products because they figure there'll be another new iFi product just around the corner anyway. A simpler line-up will provide a bit more surety to users, and presumably allow iFi to concentrate on making each product as best as possible to stand out from the crowd.
Would love it if companies in general (not just iFi) went more with this approach. Obviously, I don't run a company and maybe the many-new-products model is working well for business, since everyone seems to buy out of FOMO. But you know, the world is burning, so less products that stay top of the line for longer would get my vote.
