Sean LeFebvre purchased a pair of the MK II isolation platforms and appreciated them so much he then acquired a pair of our MK III platforms (now GP3A). Sean kindly agreed to put his feelings into words for us and this is what he had to say:

“Derrick Francis of Tough Nut Audio is an artisan, talented engineer, serious audiophile and beyond passionate craftsman. All the ingredients one would need to produce some of the best isolation platforms I’ve ever used. For reference, my setup is considered “high end” with professional grade components from EMM Labs and Antipodes, wiring from MIT and Nordost and critically acclaimed Audio Vector and Gershman Acoustic speakers. I was searching for new platforms for my recently upgraded Rogue Audio M180 (Dark Ed.) Monoblock’s and I by chance stumbled on a platform from Tough Nut Audio. In talking with Derrick, he agreed he would build bespoke platforms for the M180’s. During the entire process, Derrick would share design plans with me – some of it over my head to be honest but I knew what he was trying to accomplish. The level of detail and thought put behind these platforms is astonishing. The end product is absolutely high-end audiophile, that would be at home in the most expensive setups. At a very high level, the way the platforms are designed and engineered; they dissipate the energy from the monstrous M180’s outwards and away from the amps which in my opinion has dramatically brought down the noise floor. The vibrations from the speakers are also channeled away from the actual amps which help reduce tube resonance and microphonics, improving the imaging and increasing the soundstage in both depth and width. The level of detail that has gone into the design, from the original rendering to the final product is simply awe-inspiring. One should never under-estimate how important tweaks like these platforms can have on the performance of one’s rig. Adding these platforms to my system has redefined for me the cost to performance ratio. Without hesitation, I would highly recommend anyone who’s striving for that final 10%, give Derrick and Tough Nut Audio serious consideration. This is a world-class product produced by an absolutely talented and perhaps overly passionate individual. Nothing wrong with that ?
Thank you Derrick!”
