Carbon Tuning Discs is a spinoff of the new Atmosphere SX Loom where they are placed inside cables at key locations and are instrumental in creating the SX sound. Based on SR's patented UEF technology, each disc gets treated with a unique UEF compound that interacts with EM fields wherever you place them in your system or on cables to improve sound quality. The conductive carbon fiber material of the disc enhances the interaction between the UEF compound and the surrounding EM fields where it is placed.

Two different balances for one perfect sound: It is important to find applications for both Gold and Purple Tuning Discs in your system as their combined application creates a full sound. The Gold- Carbon Tuning Discs flesh out rich harmonics combined with a clarifying effect in the sound field for a more lifelike and holographic presentation. Purple- Carbon Tuning Discs get treated with a UEF compound that enhances clarity and extension in the soundstage even beyond Gold while maintaining a musical balance when carefully placed.

We suggest that you experiment with different locations in and on your system and cables to find your perfect match. Lastly, we recommend that you not overdo it - Carbon Tuning Discs are very powerful and should be treated as a seasoning for your audio system, sold with a no-risk 30-day money-back guarantee. Tip: try them on the circuit breaker in your breaker box...

Carbon Tuning Discs can be used to tune any cable similarly to the UEF Tuning Circuits found in Atmosphere SX, Galileo SX, and SRX cables, so you get a sense of the Synergistic Research UEF sound no matter what cable brand you may have in your system. Also, a dramatic impact with the Foundation Series cables.

Global MSRP is $199.95 for a pack of 4 (2 Purple, 2 Gold)


"...I was amazed at the change these tiny bits of carbon fiber made in the sound of my system. I used them on the XLR cables connecting my preamp and electronic crossover together. The change in the soundstage was obvious when the dots were reversed, and I ended up using them with the gold dots on the preamp end and the purple dots on the electronic crossover side for their effect on expansion of the soundstage, which solidified and expanded. Next, I plan on buying another set to try on my DAC or turntable cables. Thanks for the excellent and relatively inexpensive tweak!"

"...what an unbelievable experience, I honestly did not expect something so small and simple could affect expensive interconnects as incredible as these disc's! I'm just blown away with the detail, and separation that I heard. The sound was crisp, powerful and yet smooth. One would think you just bought upgraded equipment worth 10s of thousand dollars to get that type of sound! Great work SR!!"

"...very positive effect, experimentation with placement needed to get maximum benefit. Hard to believe such a small device can make such a change in sound. It’s a must try with the money back guarantee..." 

"...fantastic tweak to voice your system. I have no idea how it works but they do precisely what is been advertised. The combination of purple and gold carefully placed can do wonders with that last bit of voicing..."

"...the SR Carbon Tuning Discs are a sensational product. Way beyond the ECT in impact.... if you want much higher fidelity from your system they are a must have. Using the Purple Discs on my SR Excite XLR's and the Gold Discs on my SR Excite Speaker cables. Another level altogether..."

"...I wasn't sure what to expect, but with the 30 day trial policy, I figured that there was nothing to lose. I put the gold discs on the interconnects between my preamp and amps and the purple on the interconnects between my DAC and preamp. In my system and to my ears, the effect was anything but subtle. The sound became both clearer and more relaxed with enhanced spaciousness--it was more 'in the room." Bass was enhanced in terms of extension, definition and it clearly hit harder. The noise floor was lowered further and I now hear some low level cues for example in live recordings that I have never heard before. Decays last forever and soundstage depth was enhanced as well. I ordered another box to experiment with on my digital setup..."
