G'day guys,
               Found another tweak that I'm impressed with ..I installed these caps couple of weeks back "Noise stopper Gold plated Copper RCA caps". I found them here on ebay.  
http://www.ebay.com.au/itm/251210422917?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_2093wt_1163 ..

I remembered hearing about these caps years ago and never really thought about them until recent .They are reported to stop RF and EMF interference, well once again the sceptical me has been put to bed.. I really didn't think they would work and thought if nothing else they are attractive dust covers . So I decided why not cover my excess inputs and outputs ,which means I needed 60 of them . In total It wasn't an expensive exercise only spending $49 bucks .

O.k the serious stuff , I'd just finished watching the new James Bond Movie Sky Fall  and the knock came at my door ,Postie with a package, it was the Gold caps.. I plugged them on all the spare RCA's and started the movie again playing the last 20 minutes . Immediately there was more crispness in the highs,  more silence , the sound stage had changed and it was very noticeable . I was stunned and started the movie from the start and watched it through for a second time yep it was better( I love that movie my favourite Bond movie to date).. Since then I have played a lot of music and movies revisiting a lot of the music that I just finished tunning my system with .... Has anyone else tried this tweak it certainly worked for me..

Hello Rick!

How cool that such an inexpensive upgrade made such a noticeable difference in so many areas. I have seen these EFI noise eliminator listed in some of the higher end catalogs but usually they are ridiculously priced. Thank you for sharing your audio find with us.

Also, great to hear from you!

Regards,
Joe

G'day Joe,
I thought I'd like to share the great value of theses caps .. My pure silver XLR interconnects come from the same ebayer ( you can see them in my pics).. They are ridiculously cheap as well for there build quality around 1/3 cheaper on the average than else where .He also sells Pure silver Litz RCA Interconnects to match the XLRs.I might take the plunge down the track and also try them.

Cheers Mav,

I wonder how these things work. I guess shielding an unused input prevents stray RF from entering. I once had a Soundcraftsmen Pre Amp that I had to put shorting RCA's on the unused Phono 2 Input to prevent noise. I at first thought these caps had some sort of a resistor in them. Maybe I'll try some.

G'day Skytrooper,
               I also have one shorting plug on my Denon 3910 Coaxial output that I built years back ,it makes a small  difference in improving silence in the sound stage   http://www.agoraquest.com/viewtopic.php?topic=31533&forum=65&start=30&select_page_number=3   but these cheep copper caps seem to have given me amore noticeable difference..
 
              I originally thought of using Cardas caps  http://www.ebay.com.au/itm/170724195845?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_3389wt_927  but just couldn't warrant the cost at 4 for around $20 or $5 each ... that means $300 bucks for 60..
 
          I don't know wether the build material between the two different caps would make a noticeable difference , but the chance  to experiment for $50 bucks was to hard to pass up .  Mav.

G'day guys,
                  Just been playing with the RCA  caps . I had to hear the difference again, to confirm it wasn't the old placebo effect. Well I removed all 60 and listened and watched  I scene of a movie  and then replaced them back again, yep their is a huge difference in the sound stage being lowered and highs being extended and cleaner..
 
                   Tweaking my curiosity I then googled these caps just to see other peoples responses and  ideas about them and discovered this   http://www.audioelevation.co.uk/cartv3/Details_options.asp?ProductID=431  ..I hadn't even thought about a running in time on the copper caps . The XLR caps I new about because I can pick them up for $14 bucks  a pair from the same ebay site I purchased the RCA's..  Mav.
