Downgrade. The tier competitor to the 3050 would be the AVC X6500 or newer AVC X6700. You will experience a fair drop in headroom from the 3050 to the X4500. The X6500 is still lower but a lot closer than the X4500. Personally I find the signatures of both makes to be quite close and would be happy with either. The Denon certainly has the better room EQ in Audyssey XT32 plus the App for fine tuning.
