Anyone tested the Synergistic Research Vibratron ?

Yes. Waste of money.

No, but I'm considering a go with the Ripoffatron.

I have installed the Synergistic Research Acoustic Art Room Treatment System in my house. After adjusting the location of the system's resonating devices, my sound has never sounded better. I think this is a well thought out product that allows for tuning anyones room to their sound system. Peter at Synergistic Research (a California,USA company) was very helpful and patient in helping me find the best location for the devices.
Last night was symphony night and I was fortunate to hear Zuill Bailey playing his 1693 Matteo Gofriller cello from the third row. Coming home I put on his CD (Telarc 32664-02) Brahms Works for Cello and Piano. It was like having Mr. Bailey playing live in my house. The SR System has made a big difference in harmonics, quality of note decay and imaging. I have also found it to be a great improvement in jazz reccordings. The system took me several hours to find the optimal placement location. The system is well worth the money and time to install.

Thanks for taking the time to address this question.
I wonder what the basis of Chadeffect's and Audiofeil's comments is. Have you actually tested the devices and found no or a negative effect?
Davidprichard, has anyone else corraborated the described effects on your room acoustics in a 'blind' fashion? It should be pretty simple to have a friend or family member listen to music with and without the devices in place. What would be the effect of similar glasses placed in the positions you describe as critical for the Art system.
I can't wait to hear your answers to these questions.

Hello Roger,
Please read my post again.

My response to the question was "no"; I have not tried the product.

Hope that helps.
