I will be upgrading to a Denon 1802 this weekend. I still have an old RCA 27" TV that I use an RF converter to connect. My question is, will I see any improvement in picture if I use S-Video cables between Digital Cable, VCR, PlayStation and the Denon. Or is that a waste till I get a TV that was built at least in the 90s And I know this has been fought over many times, but considering my somewhat antiquated set up, Coax or Optical from the DVD to receiver. I might just S-Video the other stuff since I can “hide” the investment with the purchase of the Denon.
