I almost pulled the trigger on a sr6005 yesterday when I saw A4L lowered the price on a new one down to $649, which is what they were asking for a refurb., then I read that Marantz is about to announce the new SR5006 and SR6006 models which is said to have networking capability built in like the sr7005 has, which explains the price reductions on the current models. I'm now thinking I'll wait for the announcement and then make a decision which one to buy.
Hopefully the new models will be user firmware upgradeable because now only the sr7005 is. I really don't give a hoot about 3D but it could be a selling point a year or two down the road.
