I may be an outlier here but I have tried isolation platforms under my speakers, more than one pair, and can't say that I have ever heard a noticeable improvement in sound. For me, it has always begged the question, if putting your speakers on platforms was the way to go, then why don't all the high end speakers come with isolation platforms from the factory? You spend $50,000 on a set of speakers but they don't really sound their best until you spend another $5000 on a pair of Townsend Platforms? How much of our hobby is science and how much is just Kool Aid? Fair to say in this hobby, you'll never go thirsty. 🤣
