E-SST Contact Treatment


Improves the transmission of fine audio and video signals allowing information to pass undistorted across electrical connections. Like a major equipment upgrade in a jar.

“WOW!…There is a clarity, kind of like I just cleaned my eyeglasses. I now understand what all those reviewers wrote about.” customer email


Product Description

Detailed Instructions 

We start with ultra-pure silver that is specially processed and made into long micro-flakes. The silver flake is suspended in an organic fluid chosen for its dielectric and temperature characteristics and excellent sound.  Unlike most contact treatments that merely clean or lubricate a connection, E-SST is highly conductive and must be applied with care according to the directions.

E-SST will dramatically improve the sound and/or video of any system. The highs will be more extended, cleaner, clearer and better focused. The mid-range will be more transparent with more articulation and detail, yet without harshness or glare. The bass will be stronger, tighter, and quicker. The soundstage will take on a more natural presence. With video systems, the sound improvement will be matched by the improvements to the video. Look for a cleaner, more three-dimensional picture with richer color.

” …I started in high-end audio in 1957. With all these years experience, this is one of the single highest value and return to my investment – significant improvement to the sound…” WL, customer   Click on the Reviews tab to see more customer comments.

review for E-SST Contact Treatment

  1. (verified owner):

    Stunned, I immediately noticed several benefits. First of all, the clarity and spaciousness of instruments, voices and the sound space in the recording were notably improved. Highly recommend, for sure.

  2. :

    …I also use your Ultra Vivid, the Valid Points, silver contact enhancer, all of which have improved the sound. BM, customer email

  3. :

    …results were remarkable and easily the finest I have ever encountered with a contact treatment and enhancer. The sonic results are not heard as typical “band-aid” type of push or lift in any part of the frequency range. What I heard is simply more of what is already there. It’s very much as if a scrim has been removed. Genuine improvements such as this should not be controversial in any way…my sincere congratulations on a very fine product that has how become essential to me. JH, record producer

  4. :

    I used this on all my tube feet for my BAT 75SE with great results. JJ, customer email

  5. :

    …great improvement for the money spent. JS, customer email

  6. :

    I used isopropyl alcohol and fine emery paper (actually a cardboard nail file) to clean all contacts. The nail file worked really well as I could trim it to size to fit where necessary. Valve pins took some patience and a deft hand to apply the E-SST! So far, immediately better separation, soundstage, and focus, more detail, lower noise floor, better attack, more dynamic…Very impressed! PJ, Australia, customer email

  7. (verified owner):

    Quite astonishing. I finally experience sound quality I have only dreamed of. An obvious proof that this effect is “real” (and not only resides in my mind) is that when I treated only one (previously cleaned) left channel interconnect, the soundfield was heavily moved to the left. I feel that’s beyond possible placebo.

    The same kind of obvious improvements of signal integrity after applying sst-e to more connections has summed up to a sound quality I am really happy with.

    In a world of exagerated claims and self promotion, I’m so impressed when I find a product that actually works. ESST is an extraordinary product tha is simple to use and made a significant incremental improvement as I applied it to valve pins, speaker cables and power cables. My system opened up, revealing inner detail, dynamics improved and soundstage is more accurate. I highly recommend ESST for a simple, effective product that really works!
