Does it annoy you when companies don't show the internals of electronics ?

I own four EAR products (use only 2 now).  They are brilliantly designed but use much less than SOTA parts.  All on circuit boards.  So what?  They sound great and are priced well below SOTA comparables.   They have good looks as well.   Using a 50% markup and 50% profit margin, it is difficult to image EAR making much money per unit.  They are built in the UK not China.  Labor costs are significantly higher.   Just remember, like PNB products, the cost is about 25% of the retail price and the manufacturer only gets 25% of the price as their profit.

Architecture.  I had a Muse Signature 9 CD player decades ago.   It was mediocre sounding, totally inferior to so many other players I tried after I bought it on a recommendation without hearing it (I won't do that again).  It was beautifully constructed.  Assembly is probably the least important although the Muse had a good transport.  However, component quality and assembly count towards longevity of the product.
