I can honestly say from personal experience this is utterly not true.
Are you trying to make something up to make yourself feel better because you're personally buying and endorsing an absolutely pirated knock off?
McIntosh has been excellent to me over many years, owning many components from them, and they are solid people working hard, trying to survive, the've sold me parts for my old tube amps (yes, parts can be expensive), They've shared schematics and provided my local service tech with valuable information to get them singing again and back to orig specification. Unlike some companies like Krell, Mark Levison, and Audible Illusions that wont help your local tech, attempting to fix one of their legacy products.
McIntosh as a USA company is alive, on top of that, they're very nice, hard working people. Yes; its true, not everything is still available parts wise from 60 years ago and they can't support you for everything due to the age, but they will help you as best as possible, and they do try to offer the specs info to help you find replacements parts, they go beyond most companies in this way. But here you are pirating them
I dont think you realize how expensive it is to house and store all those old parts for all those legacy products, for the just in case someone calls up and asks/needs one, They literally need to buy a whole warehouse to store them, and hire people for years and years so they can offer you that part; for that service & support help does not come cheap and your not respecting it. But I grant you, it can be very expensive. But also, that part you buy from McIntosh, also helps you retain its high value unlike that cheap knock off.
It makes me sad reading your attempts to bad mouth them, McIntosh is one the few legacy companies that is trying to do the right thing for its customers and employees; unlike many large audio companies. It's awesome they're still around and offering made in USA audio components. They're sadly expensive because of the sheer overhead costs of manufacturing here in USA.
I love they idea of resurrecting old amps, audio components and old designs that are long gone and bring them back alive; but doing it in this way is really bad, your consciously supporting straight out stolen identity it's a pirated knock off and is virtually a fake pretending to be McIntosh when they are simply are not, and virtually stealing and profiting from an active USA company that created that amp; that's is a pretty low blow and morally bad for the ones buying it.
I'm too guilty of buying Made in China audio gear and no name clones, but this amp below is straight out piracy and as fake as a chinese made Ferrari. If someone is going to benefit from copying the design and schematic, at least use a different look and chassis; and certainly call it something else. I'm actually very surprised AK moderators have been finding this thread of a pirated audio product being promoted and endorsed here on AK by letting this continue.
