The little big company that so many people loved is not the same company anymore. There's so much that I want to say about this, but out of respect, I won't. Instead, I'll simply mention one of the largest problems that may come from this maneuver...
Here's the thing. Even today, McIntosh is one of the largest and most well-known hi-fi brands in the world. Their products draw tons of customers to B&M stores each and every day. So the big question is, what will happen if people begin to lose confidence in this legendary brand? Obviously nobody has the answer, but if I had to guess, I'm thinking a lot of people may end up getting bernt.
I mean - why in the hell would anybody buy from a dealer now? What's the motivation? Can most dealers afford to offer you no-interest financing for up to two-years? Will they be able to have McIntosh drop-ship a brand-spankin' new unit to your doorstep only two days after you place the order? Will the dealer give you a 60-day trial period on that MA8000 or whatever?
Now if McIntosh only sold a very limited amount of products on Amazon, then perhaps this wouldn't be a problem. Likewise, if they gave their dealers special accommodations that would balance out the advantages that Amazon has, then things may ultimately be OK. But that's not at all what's going on, and quite frankly, it's a slap in the face to everybody who've invested time and money into the brand.
That's just my PG-13 take on the situation.
