More to point:
Ir would be an absolute shame if Outlaw were to fail. Though they seemingly have had a good, successful run for a while. Since I haven't had a bad experience yet, I'm also loathe to consider not buying again from them if the product fits my need and budget.
Admittedly, as sexy as the 975 comes across at the price point it sits in, that is one product I wouldn't consider for myself, maybe not even the 976. But the Amps and Subs, and possibly the speakers... yes.
Moreover, having dealt with D&M/Sound United CS for a warranty service call, TWICE for the same issue, it is a supremely frustrating experience. That said, we humans created bureaucracy for a reason, and business employs that as a layer of protection. Jumping through Sound United's hoops sucked. Waiting two weeks for them to ship me a box and foam for my second service call was abject stupidity at its finest... all of it.
Never once did I lose my sh!t on any of their peons, though, no matter how ridiculous it got. There is never a good reason, no matter the frustration level, to act like that. That Outlaw acted like that is just as wrong, too. No, worse. It is horrible and embarrassing; completely shameful that "professionalism" bows out so readily when emotions are engaged.
Now, just short of legal pathways for failing to support their warranty, your options are few. You walk away and replace the 975. You pursue filing complaints with your state, and Massachusetts, if for no other reason than the principle behind holding a company responsible for their actions. And lastly, actually engage the services of a lawyer. Replacing the 975 would be cheaper and less stressful.
For Outlaws part, they or their repair partner should have contacted you about the condition of your 975 and informed you of what they found and did or did not do. If they found a reason to deny warranty coverage, they should have documented that and likewise informed you of their decision. And that is all that I would expect a company to do. A 'Humanistic' company might have replaced the unit if they found fault in it, but lets face it... we humans seem to be getting progressively worse at taking care of our own.
