Hmm yea I guess you’re right. Looking at 34,44, & if I can talk the boss into it, the 6400. But yea, looking at the Denon site it’s the 3500,4500,6500. But can’t find anything obvious that’s different. Hard to compare switching pages. I wonder if the imax thing will trickle down to the lower/older models? It’s just a firmware update right?
