Patmatt, you're asking for a clear "value proposition" from manufacturers. I agree. I think this is most pertinent when it comes to electronics and digital sources. IMO, we're getting products, but rarely, bang for the $, even in giga$ propositions.
I won't go into the economics behind giga$ "reference" products and min$ compromises -- we're all tolerably familiar with this argumentation.
I'll give an example: an EE friend build an *awesome* (tube) pre-amplification unit. The replacement cost of all components used (0,6 farad power supply, for example) without the casing was $2.1k, his involvement & research NOT included. In commercial parlance, we're looking at a 10x multiplier i.e., a retail price of 21k + tax, for the cost alone! (to include, distribution channel, advertising, we've got to make a living, etc).
However, that's a niche-market lemon: "who's going to buy that product", the Sales & Marketing VP might ask... The same VP could also note: "there's few enough buyers out there, if I produce the *ultimate* today, how will I survive tomorrow?"
I forgot to mention that the pre is based on modified 70's & 80's topologies, that are *cheaper* to realise today, God Bless the www.
NOT the latest, rocket-science technology.
I'm not asserting the aforementioned pre is the ultimate. I don't have the knowledge & experience. I can say it's better (by far) than my $5k pre.
So, before I buy, I join in asking manufacturers the question, "what value are you adding to my system, commensurate to the investment".
