No 3d isn't a concern to me. I'm just having a hard time choosing between a refurbished unit over the now one.
Being unfamiliar with what either offers, I'm using a refurbed Onkyo 805 as processor for a bit less than 3 years now, and it works great. It feeds a NAD amplifier that I also bought as refurbed, and that I've had for a bit less than 4 years.
It was either a new 705 or refurbed 805 for me, and I thought why not get the beefy amp for the same price, even if I won't use it. I suppose I had resale value, or usability in mind.
Word of warning, mine didn't come with the Audyssey mic, and that killed close to $20 of the savings. OTOH, that was pretty affordable, because I've heard other manufacturers charge significantly more, like Denon for instance. Still, I feel they should have made that clear on their website . . .
