It kind of sounds like they wanted you to "give us a good reason to take it back" kind of thing. I bought a ham radio transceiver once that I just didn't like the audio quality on, so I wanted to return it for a refund, less the restocking fee of 5%. I filled out the RMA return page and sent it off. About 3 hours later, I get a phone call from, I guess the owner, who was playing District Attorney and grilled me like I was a murder suspect. I just didn't like the way it sounded (Very muffled, there soon was a mod to fix the problem). After I explained it to him, he said, "You don't need to make up crap to send it back, just send it!". I tried to explain about the muffled audio on it and he just hung up on me. He lost a customer because of his attitude. The fact that every review of that radio mentioned the muffled audio didn't seem to matter to him. I bought another radio, which I still have. Being a cable atheist, I wouldn't have much patience with the burn in, even though I have enough stuff to hook them up to and do it without any real work on my part.I would rather spend my money on room treatments or cap upgrades, etc. IMHO, a bad cable can make your system sound bad, but any decent cable is equal to any other decent cable, no matter what it's for, interconnect, speaker, HDMI, etc. And spending any significant money on cables is just kinda kOOky.
