Apologize for not agreeing? That’s interesting. Not going to happen, this is a discussion forum and we are expected to politely disagree.
As a manufacturer of electronics in the US as well, and having worked for electronics manufacturers in the US for 40+ years I am quite familiar with the complexity of the supply chain and that there are components that are available only from certain suppliers in certain countries, This has been the case at least since the semiconductor hit its stride in the 1960s. Some of our parts, chips in particular, are only available from Asian suppliers. When parts become obsolete (a lot of that happened during the plant closures in the Covid scamdemic) there is no option on the primary market for chips, products that use them either need to be substantially redesigned or become obsolete, that is a business decision.
Regardless, McIntosh is an American manufacturing company, and there is substantial manufacturing of their core product in the US including some of their suppliers. There are many companies that have abandoned all of their US suppliers and manufacturing operations to partner with low bidders for the entire product, this is not McIntosh (and we hope it won’t be).
Whether McIntosh sources some or all of their stampings in the US, or circuit-boards (they don’t use turrets anymore), stuffing, etc. overseas is important but I can tell you with confidence that there is no amplifier that is 100% US sourced, it will all be a matter of percent of content plus final assembly and I’m happy that McIntosh still does at least some of this within the US.
I (we) don’t know the why of each obsolescence, likely a combination of things but McIntosh (as a division of BOSE or independently) needs to turn a profit to justify its existence. Given the two choices of streamlining the product offering to products that make money, or offshoring everything I think I’d choose the former. There is of course a “door #3 where BOSE simply retools the entire product line to become a handful of products that leverage the good McIntosh name on a bunch of cheap offshore products for maximum profit, car/mobile audio, lifestyle products, lets it exist in name only which even Clarion didn’t do, … hopefully BOSE won’t either.
