So basically here's how it will work for those of you interested in the A4L return process.
1. If you want a return for just changing your mind you have to pay shipping and you are subject to a 15% restocking fee.
2. If you want an exchange for another of the same product due to malfunction, you must go through Denon.
My experience, thus far, has been pretty painless save for the down time. I contacted A4L the day I had a problem, the guy immediately FWD my invoice and Denon's direct number and told me to have my A4L paid reciept handy.
I called Denon, was on hold 1 min and simply told them what was happening with the FR tower output and how I had tried it with and without banana plugs as well as with another speaker. He plainly stated that was everything he would have had me done and submitted my request for a shipping label yesterday. The same guy called me on my cell phone today and told me I should have a label in my inbox tonight and as soon as they scan it at FedEx they would send my new receiver out to avoid down time.
On a side note, I did call A4L back during all this and expressed how I was not interested in being apart of the refurbing process and that I don't feel like I should be subject to any extensive amounts of wait times due to this unexpected inconvenience. They guy was pretty firm in stating that all returns for the same product must go through Denon and that there wasn't much else that he could do. Denon on the other hand, has thus far very reasonable. I have not been made to jump through unnecessary hoops and they have been very pleasant to work with under the circumstances. As soon as I get the label, that bad boy is getting shipped and I will update with the total down time. I will be impressed if I get this before xmas, which Denon has assured me shouldn't be a problem at all.
Sooo we'll see.
*EDIT 10 min after the phone call from Denon, my shipping label is in my inbox as promised. I mean for as poorly as a situation like this could have gone, I'm super impressed thus far with Denon.
