Hi All, I'm starting to plan my progression to HD. As soon as the XBox 360 is release, like most people I am sure, I'll be looking to upgrade my current kit. Perhaps one of the Samsung DLP rear projector TV's - Samsung SP50L7HX? (I'm not to experienced with rear projectors but I don't fancy the burnin risks of a plasma and LCDs don't seem to cut the mustard when it comes to contrast). Currently my TV works as a monitor with all sources switched through my AV Amp - Onkyo TX-SR701E. Does upgrading to HD mean that I will need to upgrade my AV Amp as well? Perhaps at best I can use the XBox as the HD source and everything else through the amp? Cheers.
