Since I purchased my Axioms, I eventually reverted to what the vast majority of Axiom consumers do. Specifically, I sit back and enjoy an excellent sound from quality speakers. I do lurk on the forum from time to time - but I am not as active a poster as I once was. When I have questions, however, I come here as my "go to" source for trusted, non judgemental advice.
To bring closure to the topic, I studied multiple reviews - both professional and non. I perused forum topics at AVS. I PM'd several members of this forum that I have come to respect over the years. At one of their suggestions, I downloaded product manuals and answered for myself several open questions. In the end, I had 3 front runners - Onkyo 818 & 929 and the Denon x4000. All met the under $1000 criteria if purchased at A4L with the 818 available in that price range new. I eventually tossed the 929 as I don't think I would ever sell a 9 speaker plus sub set up to my wife. That left the 818 and the X4000.
Several reviews state that these 2 models were designed to go "toe to toe" with each other and it was a tough decision. In the end, I chose the X4000 with the swing factor being Airplay support. Ordered from A4L last night. So.....if I don't get too caught up in (to paraphrase JohnK) just enjoying the music and not the equipment, I will dig this thread back up in a couple of months and post my critique of the X4000 and the experience of shopping with A4L. Thanks to all for the comments and suggestions.
