I am such a perfectionist that selling other peoples products is really hard to do.  I have tried countless tweaks from many manufacturers and though some have improved the sound to some degree....nothing has really ever turned me on seriously.....until now.  A couple of years ago I heard about the PPT contact enhancer.  There is a long thread on Audiogon about it.  This $300 contact enhancer was said to completely tranform your system.  My own system is almost entirely hardwired, so for me, it had no use.  However, about one year ago PPT started to bring out other products based on this patented (enhancer) material.  These emats, ecards, Gate and Stop its are what got me interested in these products.  It was another tweak manufacturer who really peaked my interest when he stated even one $60 ecard was amazing.  I am looking for tweak things to add to my amp to make it more transparent and was already using the Dark Matter Technology Cube inside my amp.  After trying just 3 AC Stopits, 3 RCA Stopits and one Ecard inside my amp ($150 retail worth of PPT stuff) my system was on another level......way more information and reality.  Never has any tweak done this much to my system.....I cannot wait to try more PPT in my system.  Hearing this in my own system and reading all the threads on Audiogon and talking to my long time tweak buddy Mas (who has all the PPT stuff in his system) I was convinced that everyone who is serious about sound has to PPT their system.....there is simply nothing like it.  What is so cool is that all the products (except the contact enhancer) are sold with 90 day money back gaurantee.  According to PPT (as of 11-10-2019) no one has ever returned anything.  This just confirms how universal and tranformative this PPT stuff is.  Not only does the PPT stuff improve the sound but your video picture is improved and your electic bill goes down (yes, according to many). Below, I will show you close up pictures of the products, size descritions and how to use them in some detail.  They are not complicated to use but some info and pics is always nice.  Please watch the video on the PPT site as it describes the products fairly well.  Below is a list of their products and basic use:

1. "Total Contact Enhancer":  This syringe of contact enhancer can treat about 2 big systems. Once you put it on, you want to leave the connection alone as it drys and sounds better with time (even weeks later is sounds better).  $300

2. Stop Its Duplex:  This treated child protector plugs into unused AC receptacles and conditions the entire AC socket.  Amazing what it does for so little money.  Even using them on the other side of the house can improve the sound.  $20 each.

3. Stop Its RCA:  These treated RCA caps plug into any unused RCA socket and also enhance the sound.  Not as powerful as the AC ones but putting three of these on the back of my modded Oppo 205 was the first PPT thing I tried and I went....."What?!?"  $10 each.

4. Alpha Ecard:  This credit cart sized card can be used on top or underneath equipment or even inside equipment (if you are carefull).  The bottom and side edges of the card are conductive so if you mount it inside something you want to make sure it is secure and does not short against anything.  If you are unsure about this then contact me and I can help you.  One thing you can do if you are mounting it inside something is to use electrical tape on the bottom and edges to insulate it.  $60 each.

5. The original Omega Emat:  This is about 10 times the size of the Ecard and that much more powerful.  They can be placed on top of or underneath your gear and has a magnetic underside so you can stick it directly to steel bottoms or chassis covers.  Another place they make a serious improvement is mounting on the door of your AC panel.  Now only $300   7.5 inches X 10 inches.

6. Omega Emat+:  This is twice as powerful and twice the price of the original Emat listed above (same size as original).  The original mat sold for $600 and now is being discounted to $300 and this new plus version sells for $600.

7. The "Gate".  This mounts into your AC panel and will treat your entire house, making everything more efficient and making the sound and picture better.  This is the most power device from PPT.  It really should be installed by an electrical contractor for safety. $5000.

Check out the PPT site for more info and also note the special bundle prices......the more you buy, the better the value.
