Lip sync problems when watching DVD's are driving me nuts and I have had enough of putting up with them. Currently I have a Marantz SR4200, Harmon Kardon 506 LE, Panny PWD6 with an ole Mission Cinema six pack speaker setup. Sound and vision wise I am happy with the setup, I just wish that they were both in sync! As I see it I have two solutions, (a) I can get a lip sync correction box or (b) an amp with audio delay. (a) Would be the cheapest option but (b) opens up another can of worms... I also have an Xbox 360, HTPC and a digital cable box to connect to the screen, a new amp with component inputs would help with this. With this in mind I have been looking at the Yamaha DSP-AX757SE as it seems well recommended. I don't really have room for extra speakers though so I wonder if this amp would be overkill (I could possibly add a centre rear speaker)... I haven't been keeping up to date with developments of late so I'm trying to catch up now. Is the 757 worth looking at or is there something better out there? (around the £300-400 mark...).
