I'm getting the new WEGA 42" LCD rear projection tv, with a new Denon DVD player. I will be hooking it up to a DirecTV HDTV reciever and an antenna. I was told that I "needed" to get the Monster2 DVI cables @$69/each (x2) for the DVD to TV and the HDTV box to the TV, and I "needed" a Monster sound reducer (at a minimum the $199 model). Now I'm no genius when it comes to this stuff, but will I be able to tell a difference with regular cables and a regular surge protector? Thanks in advance for the responses.
