Mcintosh-Bad customer service?

Every company puts a "warranty reserve" into their pricing so they know their potential outstanding financial obligation, so if you sell before the end of the warranty period, Mac, or whoever, gets a freebie against their warranty reserve. They must love it.
It's probably hard to reasonably defend such a practice, but they get away with it.
Thank goodness for Bryston et al.

Who's taklking about shipping damage? Manufacturers won't cover damage from "misuse, abuse" etc. to anyone, even the original owner. The point we're discussing is transferability of warranty obviously without abuse from shipping, dropping, etc.
Automobiles have transferable warranties which are products that suffer more abuse in a day than an audio component will in a lifetime - temperature extremes, bad roads, crappy drivers, etc., plus they consist of thousands of components, sensors etc, but yup, if your within the warranty coverage you're covered, even if you bought it used.
Forget what warranties are supposed to do for dealers - the manufacturer already included the cost of warranty in the price you paid for the unit new, so short of damage inflicted by an owner, or UPS or FedEx, or any other caveat the manufacturer can come up with, there's no good reason why warranties should not be transferrable.
