Howdy folks, I'm back in the amp-buying market after being out of the loop for a good couple of years, so I'm turning to you all for advice, just like last time! 
Currently, I'm using my Yamaha DSP-AX757SE which I've had since early 2005ish I think, but I've only used it for audio and not for video. Now I fancy an amp that'll do both well - I don't watch much TV but play plenty of 360/PS3/Wii games as well as watching the odd Blu-Ray film, so I'm after something that'll let me plug all of those in (VGA/HDMI/Component respectively), and will upconvert the Wii to 1080p as well. I've had a look around the interwebs for advice, but everywhere seems to say that every amp is great, so I thought I'd come to you for some..."proper" advice.
My main concerns are:
-I don't want a huge loss in visual quality; like I said I've not used an amp for visual inputs before so I'd prefer any loss in quality to be as minor as possible!
-I'll be wanting one that does both video and audio through HDMI. I don't fully understand but I've read that some only do video?
-I don't want to have a drop in quality compared to what I'm using at the moment.
-My budget is between £400 and £600, but I'd prefer to stay nearer the bottom end of the budget if it can be helped!
Thanks in advance.
