MiG SX footers are an evolution of our original MiG footers developed in 2008. We start with a new specially tuned MiG resonator forged from high carbon steel and add a precision-machined Aircraft Aluminum and Carbon Fibre three-piece chassis engineered to distribute vibration through a special tuning disc and a UEF tuning element into Carbon Tungston ball bearings. For a bespoke match to your system, MiG SX has two placement options that re-tunes your component’s resonance; choose between Ambient and Pin-Point configurations and pick the option that best suits your system on a component by component basis. With MiG SX in your system, you experience a more massive and dense sound field, improved imaging, better layering of images, deeper and tighter bass, more extended high frequencies, and better mid-range clarity. In short, MiG SX improves nearly every aspect of system performance in a way that is anything but subtle. At Synergistic Research, we stand behind our products and we are confident you will be blown away by MiG SX guaranteed or your money back!

Design notes for the new MiG SX from our Lead Designer Ted Denney. “I wanted to take my original MiG footers and evolve them to incorporate the same precise sound I hear when using the world’s most expensive precision-machined multi-component isolation footers. I also wanted to preserve what it is we all love about my original MiG’s, namely their expansive soundstage and their ability to custom voice the sound of each component in your system until a synergy is reached. This unique ability to custom voice components with MiGs has been a critical element to my success in getting Best Sound at Show at trade shows like RMAF and Munich. To this end, I retuned the forged High Carbon Steel MiG resonator. We then developed a three-piece CNC machined Aircraft Aluminum and Carbon Fiber chassis for the transfer of mechanical vibration between the MiG and a special tuning disc, a UEF tuning element, and Carbon Tungsten bearings. These last three components were intentionally included so we could experiment with different materials until arriving at the correct balance of elements that would yield the best sound possible. For example, we experimented with precision bearings made from stainless steel, brass, aluminum, and carbon tungsten. To evaluate these different material options, we built MiG SX footers with different internal elements and compared them in double-blind listening tests in our reference system until we arrived at Carbon Tungsten ball bearings, which sounded best. Likewise, the tuning ring and UEF elements were altered between different materials and formulations until we arrived at just the right combination.


Interestingly we found soft tuning rings overdamped the sound of individual components in exactly the same way soft footers compress the soundstage and suck the life out of a system while different metals each had different audiable signatures with one in particular that was ultimately best suited to the overall sound of our new MiG SX. Had it not been for the ability to tune these independent elements within the MiG SX, we could never have arrived at the sound we did, nor would MiG SX be as refined and evolved as it is. It would have been impossible to design this new footer from concept to final product with its current level of performance on initial design theory alone. It was the ability to subjectively tune separate internal parts in different combinations that finally yielded a footer that combines the precise image focus and clarity of the world’s most expensive and complex machined designs while enhancing the strengths our already holographic and tunable MiG’s for the most versatile and balanced sound of any component footer without compromise”.


Tuning options.


When you place two MiG SX’s “Round Side Down” and one MiG SX “Round Side Up” under a component, as illustrated in the photo above, you hear a sharpening of soundstage focus with pinpoint image placement and tighter bass. This combination tends to work best when placing MiG SX under PowerCell line conditioners, hard drives, and digital servers or whenever you want a highly focused, less ambient sound. As a rule, most people will predominately prefer one balance over the other with at least one component sounding best in the opposite configuration, and this will give you the best of both options. For this reason, we HIGHLY recommend that you compare your two options on a component-by-component basis and listen for the arrangement that sounds best with each component in your system.


When you place two MiG SX’s “Round Side Up” and one MiG SX “Round Side Down” under a component, as illustrated in the photo above, you hear a more ambient layered sound, fuller bass, and images that are less sharp and more rounded. You may also prefer this placement if you like a liquid presentation, or if you want a vacuum tube-like sound expecially when used with solid-state phono pre-amps and D to A converters. As a rule, most people will predominately prefer one balance over the other with at least one component sounding best in the opposite configuration, and this will give you the best of both options. For this reason, we HIGHLY recommend that you compare your two options on a component-by-component basis and listen for the arrangement that sounds best with each component in your system.

“Everything matters” as the saying goes and like almost everything else in life today, somebody is always looking to stretch the envelope of what’s possible. Ted Denney is one of the fastest horses within the high-end audio race today. I’m not at the finish line with insight into every variation in these different categories, but the Orange Duplex, the Carbon Fiber Duplex Cover, and the MiG SX footers sound like they could be near the limit of “what’s possible” at this point in time.

With the addition of the Synergistic Research MiG SX Footers, the already exceptional performance of my Calyx Femto DAC was kicked up a notch with sound that was more relaxed and with more meat on the bones, so to speak. To my ears, the Calyx Femto is still one of the best DACs I have ever heard and the MiG SX Footers proved that even with this very high level of performance, there was room for improvement with the right footers.

The music has a greater sense of ease and clarity with a speedier attack and delivery.  There is a sense of more resolution and transparency with all of the vocals and instruments.  The Keith Jarrett Trio and Ben Webster Quintet had a snap and presence that wasn’t previously felt.  This morning’s Spanish piano with  Alicia deLarroccha and French piano with Walter Giesek both felt more in the room with them.  Bravo to Ted for the design and implementing the choice of materials to create this musical sound enhancement.

I have now been officially recording masters for the last three months using the MiG-SX supporting my A/D with very gratifying results.  The ultimate proof comes from client response which has been overwhelmingly outstanding.

Every client has brought up how easy it is to hear what is there and how defined everything is.  They can more clearly discern what they ask for and it is easier for me to give them what they are looking for.

One main component of mastering is definition.  It might be keeping what is there.  It might be about enhancing it.  It could be and often is about not bringing out unwanted definition in the wrong areas or spectrums.  The MiG-SX makes things more defined but to my ear always in a way that gravitates to space around the instruments, depth of stereo field and the relationship of one thing to another.  Many products that affect these areas often make one area better at the expense of losing something somewhere else.  It’s also worth noting that recordings that suffer from sibilance, seems to suffer less as you can clearly hear resolution below and above the problem frequencies which improves the overall sound.

Resonance is also dramatically affected and improved. Since most audio we perceive includes resonance from instruments or human voices, hearing that resonance more clearly really elevates the potential for a “Being There” moment.

Bottom line is that for me this is a “must have ” component.  Like most HiFi aficionados or audio enthusiasts, pro or amatuer, I have spent a considerable amount of time and financial investment choosing gear, listening, trying different cables, outlets, grounding schemes and power boxes.  The MiG-SX has dramatically improved whatever I put them under.  The ability to turn them over and try different tunings is incredible and there is always a clear winning position to my ears.

Cost ratio vs overall system performance and improvement is another “no brainer” for me.  The MiG-SX speak for themselves.
