Synergistic Research PHT - Phono Transducer

I thought each PHT contained a crystal of some kind or another.

I still wonder how they could have any effect at all, of any kind, except by perhaps changing the resonant frequency of the headshell/cartridge, and even that is a stretch of my imagination. But I have not tried one so I won't go any more negative than that.

dkzzzz, I hear you.

Just to say there are others who perceive no difference, with vs without their PHTs. If you are really curious, it is my understanding that Synergistic offers a free home trial. "Free" in the sense that after you pay for the PHT, you have the right to return it for full refund within a specified time interval. I should think that such a using one's own system and ears would trump a collection of opinions you might get here from total strangers.

For me, the question has been one of mechanism. How does the PHT work, assuming it does work? If it's just affecting resonance at the headshell, then there are cheaper solutions.

Qdrone, As I understand it, the "functional" unit of the PHT is a crystal that probably has been lying around in nature for eons. So, if it works, it probably works forever. Obviously, you may have to re-adjust the VTF of your tonearm to accommodate the added weight of the PHT sitting on the headshell. Supposedly, the weight is trivial.
