Time sure flies as it seem like not that long ago I got my Denon AVRx3000 from my wife for Christmas. Then I see that the same model is up to to a revision AVRx3600 and then I’m reminded that mine is pretty old. It seems to work well, but Im wondering if I’m not getting the latest decoding And therefore the best sound. For example, the 3000 does not have atmos. Is having an atmos receiver a benefit even if you‘re still only running 5.1 setup? It looks like the amplifier specs are identical except the 3600 is a 9.1 which I really don’t see myself going to anytime soon. Is the virtual height elevation a good upgrade?
