I can't find an answer searching and apologise if this has been covered thoroughly.

I have an older model Mit (WS65311) that is capable of 480i/480p & 1080i through component video. I am using a Pioneer VSX1015TX receiver.

I haven't really given HD much thought since the few times I have seen it on my television is through the HD channels my cable provider puts out and nothing has "wowed" me.

Would a blue-ray player be noticeably better on my set or is this one tech that I should wait on and combine with a future television upgrade?
