Hershon: It's clear to me you are looking to upgrade your system....why not upgrade the one area you can be sure will make a huge difference...SPEAKERS...If you can buy a $200 cable and a DVD player and a receiver, it sounds to me like you should have no problem at all buying speakers that suit you.
I'm sure the Orbs are fine, but to me, buying cables and players and receivers to improve a system's sound is the least effective way to do it. Live with what you've got or make a meaningful upgrade.
