So I'll preface my Q by saying I don't really know anything about running a business. I have to assume there's evidence of market demand on their side, although this is a somewhat unique situation given what happened with AKM.
But, at this point I'm struggling to understand the evolution of Toppings product lines. They seem to have literally set the new bar for price/performance value but are reiterating existing devices when there's so many other avenues where they could almost certainly compete within top tiers:
Meizu Hifi Pro replacement (moderate power at paperclip sizes)
Multi-channel DACs (Okto8's are still backordered 6+ weeks, even putting out something comparable and keeping it in stock would be huge)
Benchmark AHB/Purifi competition (rumored for some time to be on the way but still no previews that I'm aware of)
Qudelix/ES100 competitor (both good in their own right but some room for improvement)
MiniDSP in general (good stuff but always seem to fumble in weird ways in the last mile; DIRAC-enabled Topping has a nice ring to it)
ADC comparable to price/performance ratio of existing DACs
Having wirtten all that I'm not even sure what my Q is, I guess I'm just confused about why we're starting to see, basically, v2-v3's of already amazing, beyond audibly transparent gear instead of outward expansion.
