This looks like a very tasty gadget, an A/V amp with 2xDVI inputs and 1xDVI output, due out early next year:

It's slated for a January 2005 release in the US for about $1,600, but I can't find any info on when it might be available in Europe and what the estimated cost might be.
I tried the UK Marantz website and there is no mention of this model, and the US website doesn't work in Firefox or IE for me! (Some plugin it requires but can't download I think.)
Originally I was looking at the Denon AVC-A1Xv, but at £4,000 that's a tad expensive and it's one hell of a big bugger!

If I'm going to get a new home cinema setup, a matching silver setup with DVI and coaxial digital sound is a must - and with 2 DVI inputs I could use an LCD TV from one of my PCs too
