Handmade in California. Transform your turntable’s performance dramatically with the NEW Synergistic Research PHT! PHT is an acronym for "Phono Transducer" and is an evolution of SR’s award winning UEF technology.  Available in two different strains, Type ’I’ PHT adds a holographic ethereal dream like quality to your records while Type ’S’ is all about focus and clarity with musicality. To get started simply apply 1 micro PHT transducer, Type ’I or Type ’S’ to the top of your phono cartridge or head-shell for an immediate and dramatic transformation. Improvements include a lower nose floor, increased resolution, improved bass extension with increased air, and sound staging. 

Michael Fremer of Stereophile wrote:

"...adding that blue PHT produced an ear-popping, Cinerama-like, wraparound soundstage, and an overall sound even less tethered to the speaker positions. The image focus was increasing razor sharpness, and there was greater front-to-back separation of sources within the soundstage... Decays were longer, and the backgrounds they faded into were ’blacker’... with the blue PHT in place the sound was clearly better overall, with improved focus, three-dimensionality, and transparency... "

Dato’ Danon Han of Mono&Stereo wrote:

"...Synergistic Research PHT really work as advertised. I was jaw dropped as to its improvement over my analog set up. They are not expensive compare to the improvement gained. Please check them out and you may save quite a bit (or a lot) in your next upgrade. You can expect images solidifies, greater separation, cleaner mid and low, more dynamic and transient of energy, lower noise floor allowing the above to shine through and detail unheard of, and enjoy!"

Customer feedback:
"...first, I would hardly find some one to give $150 for my used Ortofon X5-MC ($275 when I bought it, $550 last year). Then I would have to add some $600 (or $800?, or more?) to buy a catridge to give me the sound I now have with the Blue Velvet. Dramatic improvement? very close to that. It is not that you have suddenly to jump back, but as in 3D movies, is much easier to experiencie the sound. Yes, there is lower noise floor, more detail, more extended bass and treble, less harsh, more focus, less congestion ... but the most important gain is about music, art, beauty, feeling ... not about words. And for $125? Very ... very good deal. Very interesting to try this on good budget cartridges like 2M Red, Denon 103, Grado Prestige series, Shelter 201, Clearaudio Concept, and the like."

" a word (or two or three); more musical - notes seem clearer and there is information there I have not heard before..."

Every 90-days or so SR will have a new crop of 2 new strains of precision handmade micro PHTs, one Type ’I’ and one Type ’S’ for you to try in your system for 30-days risk-free.
