New setup

Good tips and now I need to contact a dealer. 

In my younger days as an audiophile I much enjoyed Yamaha separates. 

No one can tell you the outcome of comparison of these if they have not used them in comparison. Preferences determine nothing in terms of results. I'm afraid you will simply have to conduct adequate research of resources on them and try to hear... 

I tend to agree with greg that any of them would likely be an upgrade. However, again, only comparison would tell if/how much. If you want more flexibility to manage the sound and typically higher sound quality at price point, look for separate pre/amp. If you are doing a lot of video I can see an integrated, but if primarily two channel, I would push for separates. It may take a bit more cash, but the rewards can be much higher sonically. There is a HUGE spectrum of performance, and separates usually gets you much further along. 

Enjoy your quest! 

HI Douglas,

Yes I do a lot of both indeed Video and music. 

Among the three brands you listed, Accuphase would be my first and last choice....I currently own E-650. 

For under $5k used, I would add the Hegel h360 or the McIntosh ma6900
