Jeff Rowland Synergy's sorbothane feet.

I finally bought a wonderful Jeff Rowland Synergy 1 preamplifier to drive my JRDG Model One, but the eight sorbothane feet included in the box are not the small classical sorbothane disks shown in the Synergy's manual. They are small cylinder (upper four) or half-sphere (lower four) shaped sorbothane feet, and the seller told me that they were sometimes used by JRDG at the time he bought the preamplifier.

I tested other various feet types and I verified that the Synergy's performance is extremely sensitive to them.

May someone suggest me the best feet for the Synergy? May someone please suggest me where I can buy the original feet at a cheeper price respect to the 106 Euros requested me by the JRDG italian importer?

Thank you very much for your help!

Regards.

Luca

Buon giorno Luca, I will contact the factory tomorrow.... Will ask them why they switched footers on Synergy... And what the best alternative might be.

Luca, glad you received a response directly from Rowland support. It is my understanding that compliant Sorbotane footers are no longer stocked, because of possible long term structural deterioration. Have you considered looking into third party non-compliant footers... E.g. Nordost Sort Kones, or various StillPoints?

Saluti, G.

I bought the compliant Sorbothane pads from Rowland and I am waiting for them. I know the effect of time on Sorbothane, but it may be that these pads are the ones JRDG supplies along with current JRDG electronics.

Grazie, ciao.

Ciao Luca, glad you could source compliant pads... the factory must have had some remanents from old stock. They no longer use sorbotane pads for current products. The last product I have seen shipped with sorbotane pads was the M312 Since then, for heavier amplifiers they utilize bolt-on Delrin balls. Not sure what material is now being used under lighter devices like preamps.

Saluti, Guido

Every foot you put under any product will change the sound. There is no correct one.... Experimentation is the key...sometimes it will improve the sound, sometimes not. Most often, it will be a change that you cannot decide about. I made feet a number of years ago called Pon-Tunes. They increased the air around the instruments, increased the depth, etc....most people liked them some didn't. Its all a legitimate call.

Sorbothane pads arrived.... A very huge increase in the Synergy's performance! Now it sounds as I read in the various reviews.

Thank you for your help!

Hi Luca, what power cord and interconnects are you using on your Sinergy?

I use Mogami 2549 interconnects and industrial neoprene-jacketed power cables (2.5 mmq) for water/wet environments.

Ciao.
