Exclusive Review: Tough Nut Audio Footers Are A Game-Changer Upgrade For Audiophile Hi-Fi Equipment
Affordable vibration control and isolation that may transform your high-fidelity audio sound system.
Review By Rick Becker

   Breaking into the high end for manufacturers has a fairly straightforward path, although there are variations on this theme. First, you come up with a product, and then you present it at a show. There you will meet reviewers and hopefully convince them to work their magic on your product to get the word out and generate consumer interest, either by direct sales or a distribution channel. Each of these steps has its own challenges and pitfalls, but it's a lot easier than, say, mining for rare earth metals or building commercial or military aircraft (drones excepted). Witness the large number of manufacturers in high end audio today, and their global reach. In my audio show coverage, I pay particular attention to new presenters, not just new products. This review explores a product from one such company with a growing reputation that I've been watching closely for several years.

Wearing my photojournalist hat (actually, just a Press Pass), I first encountered Derrick Francis at the Toronto show in 2022, where he was premiering Tough Nut's first audio equipment rack. The word "engineer" quickly came to mind when I looked at it, but talking with him, I had a sense that he was a knowledgeable industrial designer with the makings of a successful entrepreneur, and it was clear his wife, Deirdre, was deeply involved and committed to the business. That's always a good sign in a budding micro-business. They kept showing up at the Canadian shows, and their rack kept looking better each year as additional technology was incorporated.  Their product line kept expanding, too, with the addition of amp stands and turntable platforms.

The footers reviewed here are a spin-off category from the footers developed for their racks. I've championed this category for years, going back more than two decades to the first reviews of Stillpoints, Boston Audio Design, and Soundeck (then known as Sound Damped Steel). And I have a shoebox full of others, comprising various elastic materials, wood, ceramic, and steel balls, and concave retaining fixtures.

At the Montreal and Toronto shows, Tough Nut has partnered with other manufacturers and provided well-thought-out displays to explain its product line and the engineering research behind it. Derrick himself is an excellent presenter, capable of clearly explaining his work to any ear he can capture. Their website contains a lot of product information and pricing, but there is also useful information there that is more difficult to find. They openly invite enquiries about special needs or custom work. A photo gallery reveals the depth of their design capabilities.

Isolation Footers
While I've been interested in isolation footers of many types, I've been particularly enthusiastic about those designed for loudspeakers in recent years. There has been a huge shift away from the traditional spikes that have dominated that sub-category toward footers designed to absorb vibration and eliminate or minimize the transfer of vibration from the speaker cabinet to the floor, and vice versa. While IsoAcoustics (also made in the Greater Toronto Area of Canada) was not the first to develop such footers, they picked up the ball and ran with it in a big way to become the driving force of this transition. Other manufacturers of both speakers and components paid attention.

Time and again I commented on IsoAcoustics' rooms at shows where they presented direct comparisons of identical speakers fitted with OEM spikes and their speaker isolation footers. IsoAcoustics has also worked directly with speaker manufacturers to develop proprietary footers for those brands, while other speaker manufacturers have followed suit using their own internal design departments. At the upper end of the speaker category, it's rare to find a manufacturer who hasn't paid special attention to isolation footer design. At the entry and mid-level, manufacturers have begun to pay attention, resulting in more modest attempts while keeping an eye on their bottom line. More commonly, it is left to the customer as well as purchasers of older used speakers to source an aftermarket footer. That's where Tough Nut comes into play.

Tough Nut Footers
Tough Nut isolation footers come in two forms: cone-shaped and cylindrical. The cone footers have a bit more give or flex and reflect airborne vibrations away from the footer. (Yes, who would have thought?) They are most suitable for smaller items like turntables, CD players, tube amps, and smaller speakers where they screw right into the chassis, replacing the OEM feet. For tall floorstanding, heavier speakers, a cylindrical version was developed, which is capable of supporting up to 350 pounds with a set of four. The cone-shaped and cylindrical styles each come in four sizes to accommodate different weight components, and with either metric or English thread sizes. You want to order the right size so it does not have too much or too little give in order to maximize the effectiveness of the footers.

I requested large-size cylindrical footers with 3/8-16 thread for my Acora speakers that weigh about 175 pounds each. A set of four large footers lists for $217 and will support up to 220 pounds. There is a stainless steel cap that threads onto and is bonded to the rubber cylinder, adding compression and enhancing the rubber's ability to absorb vibration by converting it to heat. Derrick pointed out that sound travels through rubber at 60 meters per second, while it travels through steel at greater than 1500 m/s. An additional EPDM rubber washer isolates the stainless steel barrel from the speaker's weight-bearing surface. A tightening nut was shown on the website, but none was included. In any case, I preferred the look of the footers drawn down tight to the plinth.

The only real downside to the design is that they are thread-specific. The threads are permanently embedded in the rubber and cannot be changed if you replace your speakers and need a different thread size. But given the modest cost and the likelihood that used footers will be highly marketable, this should not be a deterrent. You can even include them as a marketing feature when the time comes to sell your speakers. To be clear, if you need a different thread size than is listed for the size footer you need, Derrick will accommodate you.

I'm sure there will be readers who appreciate technical information, but rather than spend hours regurgitating it, I will simply refer you to their website for supporting data. This is particularly interesting because Tough Nut differs from the approach used by two other footers I've reviewed: the Stack Audio Auva 100 and the IsoAcoustics GAIA I Neo. All three have their unique approach, and it is worth investigating the manufacturer's websites if you are technically inclined. Personally, I found proof of their value in listening with them.

Getting Down To Work
I had the Stack Audio Auva 100 and the new IsoAcoustics GAIA I Neo on hand for comparison with the Tough Nut. Derrick knew this in advance, and he was eager to hear my findings, confident his product would stand up to the competition. The Stack Auva and IsoAcoustics GAIA NEO both have removable threaded inserts, allowing for different thread sizes in the future. The threaded spindles in the Tough Nut footers are embedded in the rubber during manufacture and cannot be interchanged. There is also a hexagonal insert at the end of the threaded shaft for using an Allen wrench to make micro-adjustments for speaker alignment with laser pointers. I've watched Val Cora make such adjustments when he delivered the Acora speakers, and it can sonically take a speaker to the next level if you know how to do it. (I should have videotaped him.) As a reviewer, I'm frequently moving gear, and the effort would be for naught, but if you own your "forever" speakers and never move them, I highly recommend precision alignment.

To install the footers, I merely tilted the Acora speakers to one side and slid a piece of 2x4 on edge under the speaker with my foot, as shown below. This gave me plenty of clearance to remove and install two footers. I simply repeated the process from the other side to finish the job. Depending on the weight and dimensions of your speaker, you may want a second person to steady the speaker for you, or simply lay it down on the floor. Laying it on a sofa cushion will allow you to get your hands under it to right it again. If it's really heavy, search "lifting lever" for some mechanical help.

The footers also come with a pad to use under the rubber feet if you are worried about leaving black marks on wood flooring, though a few swipes with Grade #0000 steel wool will likely remove any marks. The pads also facilitate sliding the speakers on smooth surfaces. I didn't use the pads and noticed the speakers do not slide without them. When moving the Acora to test some stand-mounted monitors, I simply tilted the speaker onto one foot and pivoted it around to "walk" it out of the way. The footers left no marks on my wood floors.

The Listening
From what I had learned from Derrick and read about the footers on his website, I wasn't expecting to be disappointed. And I wasn't. It was immediately clear that Tough Nut footers are a first-class product. Like the Stack and IsoAcoustics footers, the Tough Nuts elevated the world-class Acora speakers even higher with resolution that rivaled the flagship models of the elite speaker manufacturers. As an elder reviewer, my top priorities include resolution and transparency. I ran my compilation CD with some challenging song lyrics through its paces, and the Tough Nut enabled the Acora to produce the highest resolution I have heard from it yet. One song, by Richard Thompson with a thick English accent, was particularly improved for the first time. Here's a YouTube video of "1952 Vincent Black Lightning" that is even clearer than my recording and if you activate the captioning, you can see how the subtitled lyrics struggle to keep up. I've found cognitive recognition of difficult lyrics to be a very useful tool over the years.

The reduction of smearing also reveals a lower noise floor, which lets timbre, attacks, and decay emerge with greater presence. Macro and micro dynamics all become more pronounced. The notes gain more tonal color, and the musicians' phrasing becomes more evident. The music comes to life, inching toward live music as close as the recording will allow.

How does it compare with the Stack Audio AUVA 100 and the IsoAcoustics GAIA I Neo, you ask? I've set you up for a shoot-out, but being a relatively kind soul, my weapon of choice is water pistols. You can read my detailed reactions to those other footers in the original reviews I have linked above. Having listened to all three footers, using an identical playlist, within a two-hour window, I can provide you with a more accurate comparison.

Foremost, they are all in the same league. If you already own one of these three, I would say "Keep what you have and spend your money elsewhere, on another tweak, perhaps footers for a component." Between the Stack and the IsoAcoustics, if I walked into the room blindfolded, I could only guess which one was being used. Only with a familiar piece of music on a familiar rig might I be certain. The resolution and transparency are almost identical; the IsoAcoustics has slightly more bloom than the Stack. For a tube lover, that might be a siren call. Only on a direct comparison with the footers in sight could I reliably ascertain these slight differences.

With the Tough Nut, the story gets more complex. The resolution is slightly better than the Stack and the IsoAcoustics, but it comes at a cost. It is also a touch drier sound, leaning more toward solid-state than a tube sound with more bloom. There is less room tone or ambient sound from the venue. It is more like you are hearing the music with greater precision by being closer to the orchestra, but missing out on the reverberations of the concert hall. The appeal of this is going to be a personal call. Some listeners prefer to hear exactly what's in the recording; others like it colored to some degree to make it more palpable / enjoyable / musical (take your pick). This is not a big difference, but it is noticeable, and I might be able to identify the Tough Nut if I came into a familiar room blindfolded and heard a familiar recording.

If we were comparing amplifiers, I would say the Tough Nut is more like an Audio Research tube amp, while the other two are more like a VAC amp. And even there, you could roll some tubes in either of those amps and achieve a greater difference than I found among these footers. It is far more important that you have one of these three footers than which one in particular you select. I reveled in the enhancement provided by all three. They all bring me much closer to the experience of live music than the stock spikes of the Acora speakers. And they all create an ease or flow of the music that neither lulls me to sleep nor irritates me in some way. Yet the enhanced resolution gives the music a presence that encourages me to listen with more involvement. I'm not a big fan of classical music, yet I kept pulling out a compilation CD of classical music that a friend made for me, simply for the enjoyment of the music and the experience of feeling like I was in the music's venue.

Aesthetics
The Tough Nut footer is a "form follows function" design, very much in keeping with company ethos. There are no frills involved here. The polished stainless steel cup catches the eye if you intentionally look at it, but it doesn't draw any attention to itself or contribute to the aesthetics of the speaker. With the Acora, the 2" diameter of the footer neatly fits the curvature of the speaker's plinth handsomely, but on speakers without a cantilevered attachment for the footer, it will likely disappear beneath the speaker itself. The vertical height of the footer is 1.25", which is about the height of most OEM footers, so it won't significantly alter the height of the tweeter. If you don't care for the shiny brushed stainless steel, Derrick sometimes has black powder-coated barrels available for special order. Some black gaffer's tape will also take care of that with very little effort, and blend nicely with the rubber.

Value
At $434 for a set of eight, the value of the Tough Nut footer is off the charts whether you have an expensive speaker like the Acora or a high-value speaker like a Tekton Design. With the Acora, the Tough Nut boosts its performance by tens of thousands of dollars, if not $100k, pushing my mid-range model close to its flagship. With the much lighter weight of a Tekton Design…well, I'll have to get a set for my son-in-law to know for sure—and I'll get back to you. But my expectations are very high.

The other two footers are more expensive. The IsoAcoustic GAIA I Neo is available online for about $1480 for 8 footers. Their Titan Neo series for even heavier speakers is now available, I'm told. And the original GAIA series is still available at a somewhat lower cost. The Stack Audio AUVA 100 runs $1539 for a set of 8. And each of these footers costs proportionately less in smaller sizes designed for smaller speakers.

While the IsoAcoustic and Stack footers cost significantly more than the Tough Nut, they also offer more sophisticated designs that complement the elegant designs of many high end speaker manufacturers. For audiophiles or significant others who value style and presentation, the additional cost may be well worth it.

For those considering upgrading their speakers, weigh the cost of adding these footers to your existing speakers against the cost of buying new or used speakers to achieve a comparable increase in performance. And from another angle, you could consider buying a higher-quality pre-owned speaker and adding these footers, versus buying a far more expensive brand-new speaker from a top manufacturer. Whichever path you choose, these aftermarket footers help level the playing field among those with more limited means and those who can spend more lavishly. For comparison, I noted that Wilson Audio offers their Acoustic Diode set of 8 footers for $3400 in their company store.

Summary
The development of vibration-absorbing aftermarket footers has spurred a sea-change in loudspeaker design, with major speaker manufacturers now incorporating them as OEM. This evolution is spilling over into component design as well, and Tough Nut footers can be applied there, too. The same technology easily scales down for component footers and isolation platforms. For Derrick Francis at Tough Nut, the footers were a spin-off of their component stands and platforms, which should also be on your radar. From my experience with these speaker footers, I suspect their other products are outstanding, too, offering comparable high value. The technology and fine woodworking of their platforms are especially attractive. While the Tough Nut footers surpassed a couple of their chief competitors in resolution, it is their more affordable price that will attract many people. Whether you want to boost the performance of speakers you already own, or are buying new (or used) speakers without this type of footer, I highly recommend adding the Tough Nuts. Spend a little more, and you will enjoy your music a lot more in return.
