This is an exercise in the art of designing audio gear. Much like over the top autos are out there, or over engineered watches, and so on, these products are targeting the Japanese market where serious audio nuts have small rooms in which they put large speakers and have room for one amp, one source, and so on. If enough people want them in the US or other nations, they have the parent company to help import the products. They are not mass marketing these products nor expecting huge sales volumes. I respect the approach and love seeing someone doing it right (rather than relying solely on pointless gimmicks which can often hurt the performance). While many expensive parts are unnecessarily costly, nearly all are related to actual measurable and potentially (theoretically) audible improvements in performance.
While I will never buy anything like the new Technics products, I do get what they are doing and think it is very respectable.
I would definitely not turn down a one of those amps received as a gift (hint, hint, guys - step up for all the great advice, education, and entertainment I've given you over the years).
