Hey guys I decided to post this here and not the XOT thread. I got my PHTs yesterday and I'm not sure if they are a current batch I got a green and black one. I found their website comparing them to weed and the current is Blue Velvet and Purple Haze. I also don't know which is type I or type S.

So my first impression is they do something. I doubt in a blind test I could pick which is which or without. I did think the green has more bass. I did make a recording first without then green, black and without again and I think you can hear it but the difference is very slight. Maybe some better ears would pick out differences. It reminds me when I was demoing a set of Element Copper interconnects and part of the active shielding they have enigma bullets and you can change them to change the sound a little. They did make differences but again very slight. I bought the cables but I'm not sure how wise that was. All of this makes me think of something my father said " A fool and his money soon go different ways"

I'm not even sure my guy at the Cable company even knows what they do and why it works. He told me at first that it was the sound filling the room that influences how the cartridge is picking up the sound in the room and the PHT reacts positively. I said so if my turn table is in a different room with virtually no sound does that mean it won't work and he kind of back tracked a little.
I'm still skeptical and I may keep them but I can't see having more than one set, unless you so much money and it really doesn't matter. It might be fun to swap out the different PHTs.

The black and green ones are the current generation. These must work depending on one's system. In my system the black one was a real ear opener. My friend couldn't beleive the difference in sound with the black pht on, night to day difference.

It's weird you had a little difference. Looking forward to see what the next ones are.

Maybe the purple and blue ones are the newest. Go to their website and you will see.

What if my guy was right and it does have something to do with the sound in the room. My equipment in the room behind and 90% less sound.

Which is type I and S?

OK here are two 60 second samples in 32/96 first black 2nd green. On this track I can't hear any difference. I choose we transfer over send space because send space can look scary for those who never used it. The link is only good for 7 days.

Another thing these are easy to loose. I very carefully placed the black one back in the $0.002 container they shipped them in and place in my top file drawer. After reading Moons post I thought I should try the black again. So I reached in the drawer and moved the container to the desk. I didn't see the gray foam they compress into the plastic container had expanded and pushed the cap off. After about a half hour looking for it I found it. I think for $200 they should come with a more reliable container.

I think if wanted to compare them to drugs they look a lot like micro-dot acid back from the day.

Oldskooldude,

I finally got a set of 5 synergistic ECT's. I put 1 on each rca at the VPI junction box, 1 on each xlr at the phono stage going to the amp and the last one on the outside of the fuse holder which goes in the back of my amp. The ect's have to go on the sending end of your rca or xlr.

I was really suprised at the difference in sound . The music now has more impact, better soundstage clarity and depth , increased clarity. The clarity was there before, but now more is being revealed and is more separated in the stage from just being part of the mix. That's about the best way I can discribe it.

Oldskooldude, your discription of you can't hear the noise , but you sure can without it is bang on !!!

I will be buying another set after hearing this to go on internal fuses and transformers and 1 oN the junction box itself.. Before the addition of the ect's, I didn't beleive my vinyl listening could get much better. Boy was I wrong.

It is a big sound transformation for such little money IN this hobby or passion. I do want to try the hft's at some point. There is a 30 day money back on the pht, ect's etc if you purchase from Synergistic.

I find this discussion very interesting, especially since I have a rather modest 1980 system with King Cobra (some Diamond Back), CV-8 cables and Acoustat 2+2 speakers. I would like to step back a bit and ask if anyone with a VPI Prime with the metal finger lift a question. Have you tried layering the metal finger lift with transparent tape? I do not mean wrapping the finger lift, but placing tape only on the lift that is outside the tonearm and trimming it to the edge. I am using two layers on the top of the lift and one on the bottom. I used a sharp hobby knife to trim the tape to the edge of the lift after it was applied. Why did I do this? I placed my cart on a non moving record and lightly tapped on the finger lift with the aluminum tube that came with the 3-D arm. I gradually increased the gain until I could easily hear a resonance. It was clearly in the audible frequency range. I did not like what I heard. Then i tried the tape experiment and found an improvement. My 2 cents is that the dots are doing something similar to improve the audio source. The only down side to the tape I found is that it requires some additional weight on the opposite side of the tone arm to remain the correct azimuth balance. I used the round azimuth weight to compensate. So, here is a challenge. If the dots are an improvement in your system, try the tape dampening and determine if there is even more improvement. IF there is please comment about it and describe what you did. I have been using the tape for several months and see no reason to remove it except to try listening with another dampening material. I'm thinking of using a dip in FlexSeal liquid for comparison. You have probably seen the adds for it on TV. I'm not a salesman, just looking for the best bang for the buck.

Mr. putty

If you are referring to the dots as being the pht's, the pht's complete transform the sound . It's very substantial in every aspect, soundstage, clarity, etc. Night to day difference.

Moon,
Yes, I was referring to pht’s as “dots”. Sorry about any confusion. I guess I was having a Zen moment, wondering how and what the pht’s actually do. I’m looking forward to more information. In a minor internet moment I found reviews stating there is good improvement (bang for the buck) in using audiofile quality fuses. Since my speakers have fuses I want to know what to expect with a change to better ones. Should I start a new thread asking what members found in their experience?

I know some user who just remove the finger lift altogether and just use the cue mechanism.
