Over engineered? Well, the game we are playing is, after all, engineering. Right? It seems that there are two points of view in play. First, the best is the enemy of the good. Second, there are no winners here; everyone gets a ribbon just for participating.
To my mind, the point is to reward engineering excellence. If company A can produce a device that is SOA for a 'reasonable' price, then that is what I want to buy, regardless of whether the DAC can be subjectively distinguished from its lesser counterpart. I like excellence. But that's just me. On the other hand, if pretty good is good enough, then a consumer has a choice of a lot of other audio engines, for a lot less expense. At the same time, consumers have a lot of pretty good (and sometimes not so good) options for a lot more dollars than this particular DAC/Streamer. So you pays your money and makes your choice, depending upon what's important to you, and what your pocketbook can stand.
