Well, I wouldn't consider the sonic differences earth shaking, but you do have to short or cap all inputs and outputs. For inputs, the RF can enter through the ground circuit if left uncapped.
Actually, I consider it better to address the various jacks on the digital and video sources first. Since many of those outputs are live, they are actually radiating a lot of RF and creating havoc with the rest of your analog gear. Try finding a cap for your S-video jacks, though......and.....take a gander at the number of fittings on a new TV set or on a A/V receiver!
RF sources these days are proliferating very rapidly. Even the LED displays will emit RF. I discovered that by accident when experimenting with some lead sheeting. A sheet in front of my CD player's display noticeably increased detail, you can easily check this out as some players have displays which can be turned off.
Capping a few inputs or outputs may not amount to much, but if you zealously do all, then the improvement becomes more noticeable. I like the Cardas caps, but sometimes I use those el cheapo IC's and simply short them out or buy those really cheesy RCA's and solder them closed (those all metal ones for like 5 cents each looking like refugees from the 50's ). The good thing about those caps, in general, is that it keeps the RCA jacks from corroding.

It's the center pin that the RF couples to. What the caps do is effectively shield the center pin.

Somehow I got my thinking a little convoluted, no excuse.
A while ago, there was a brief thread on the ultra Tweeter operating in the mega and gigahertz range. There, the speculation was that RF was entering the amp through the feedback circut.

Don't need to go that high. I've found you don't need to go over much more than 100kHz or so. Check out my Ultra Super Tweeter tractrix wood horns. Still waiting for someone to make a driver for them.

I just ran this past my dogs and they are keen on the idea. With their extended hearing they've been looking for a little more bite in the upper octaves...

Wasn't aware of the S-video caps. The BNC caps have long been standard for radio use, BTW, and you can also buy them (non audiophile, of sourse) terminated with a resistive load.

Lot of stuff nowadays has RS232 for remote control. Maybe not as important since they are not part of the audio circuit?
paranoid. Since they serve remote functions, they have to live!
