Up for sale is a Neuance Audio isolation platform. I've had this platform for many years but it has seen little use due my overabundance of other isolation gear. It measures 17" length, 12" width, and 1 5/8" thickness. Neuance Audio is no longer in business, but products like this one retailed for approximately $200 back in the day. Asking price is $60, shipping included. It's in very good condition except for one scratch (as shown in the pic below), which does not affect performance. From the manufacturer: "Low mass, internally dissipating design [that] augments your components' own resonance control functions. Neuance preserves the pace, rhythm and timing of the original musical performance, offering an organic, natural and balanced presentation. The result is a product that reveals the music's dynamic, kinetic and emotional qualities.”
