Three coatings of teflon tape on each ac prong is the sweet spot for this tweak. When you put the second coating of teflon tape on the ac prong you DO NOT put it over top of the teflon tape that you already have on the ac prong...you put it right above it on the metal prong and then you push the teflon tape down to the base of the ac prong. You do the third coating of teflon tape the same way. When you put three coatings of teflon tape on each metal prong of the ac plug it takes about 21 days to settle in good. Just WAIT until you see what this does to your HDTV PICTURE !......

what was the difference in hdtdv image? I added some to my hdtv plug and am curious what you experienced.
What type of tape are you using. I've found two types of standard tape available from the supply house. One is thicker(heavier?) than the other. I would imagine the thiner tape would be easier to work in.
Also is there any advantage to using "high density" tape?
I'm using Oatey's thread seal tape with PTFE from Wal-Mart. When putting the teflon tape on the prong I first fold it longways so its thicker and so it does'nt take up much space on the prong also.
I cut it in half lengthwise first, then also fold it lengthwise. I guess the piece was 2.5" to 3" long before wrapping. You need to experiment a bit. I used a thin bamboo skewer (blunt end) to push it down hard.

Geoff

Too often I have found that on removing a tweak, I prefer the sound without it. It will be easy to replace it if I still want it. I will also try three rounds if I go back to the tape.

It should be obvious that the Teflon wrapping should not interfere with the socket clamp when the plug is fully inserted. The improvement is from absorbing acoustic energy, according to my understanding, and would be negated if the Teflon reduced the socket clamp spring force by prying the socket parts apart.
Norm, I think you will find a more open sound once you remove the teflon tape.
I did not like the tape with my Powercell SE.
The sound just keeps getting better even after 30 days with 3 coatings of Oatey's teflon tape! Before doing this latest upgrade the bass was little thin but now I can FEEL IT like I'm at a LIVE SHOW!.. Everything just sounds so SMOooOTH and more REALISTIC now. This tweak is more like a major component upgrade now!.....
Change for the sake of change is usually preferred. For awhile. But, then we make another change and are happy for another week or so. And it goes on and on ... Anything to keep the brain preoccupied and not constantly reminding us that the sound is really not very good.
Oy ve.
Perhaps if you stack a pallet with money it will act as a bass trap until Cheney can get round to your place.
It is indeed hard to fix such a poor system... ;-)))

I was laughing at our need for a constantly changing target for enjoyment of our music systems.
Moving targets do not seem to work as well with economies no matter which side is calling the shots but that does not seem to stop the "we have to do something" urge.
That should be left to the listening room!
I have been around long enough to always recheck my initial impressions. This is not to say that others might still prefer it, however.
I came back from the RMAF already sad to realize how excellent the Tidal speakers had sounded and was disappointed with my sound here. After I played some cuts that I knew well, I went through what I had done most recently. Along with HiFiSounds post, I decided to explore the teflon tape matter more closely. I tried first off to just remove the tape and listen. That was as far as I got.
I wonder if at least part of any sonic change from this tweak is the sound of the added Teflon dialectric as opposed to vibrational control. Which would explain why it's not a positive for some people?
Some folks prefer the effects of Teflon and others hate it.
I've found that cotton is the most neutral dielectric for my taste, and that Teflon comes close. Other dielectrics impart strong colorations to the sound for me. Considering that much of my system already has Teflon insulation, the small additional amount in the plug blade wrapping should not affect the overall dielectric coloration very much. Thus, I believe the improvements I hear are caused by acoustic damping.
a
...that maybe the dielectric effect might out-weigh the anti-vibration effect.
You get the best out of this tweak when you put three coatings of teflon tape on each prong. I will never remove it!...
I also meant to try this on the cheaters I use on everything except my line stage but haven't done so yet.
it takes about 21 days to settle in good
So I assume that you removed the Teflon after 21 days so that you could compare the before and after or were you just relying on your memory of how it sounded three weeks earlier?
You need at least some overlap so the tape will stick to itself and not just make a mess when you push it to the base of the prong.
When I tried this tweak I put about 3-4 layers (laps around the prong) on each prong - that seemed to be the right amount so that it was having the right effect without preventing the plug from going all the way into the socket.
Unfortunately, I didn't notice any benefits of this, but perhaps my gear is too mid-fi.

You use about 3 inches of teflon tape for each coating...3 coatings on each metal prong...9 coatings on each ac plug
OK - thanks. That's about triple what I tried. I used only about 3 inches of tape on each prong, although any more than that was enough to prevent some of the plugs from seating all the way in. I'm sure the specific plug/socket combination plays a role in this.
I'll try some more layers on the plugs that will allow it.
Cheers,
Pete
Has anyone tested the sonic difference between the "Pink" and the "White" Teflon tape.
Just wondering...

HDTV?
Maybe it is just getting burned in?
But, something to think about, the Teflon tape....
-chris
Break-in time for these HDTVs are about 800 to 1000 hours. I have more than 2000 hours on mine. I also put three coatings of teflon tape on each metal prong of the ac plug of my DirecTV HD receiver, Power Conditioner and all of my audio gear too.
