Here's the US importer of Avantgarde speakers, Jim Smith, in front of a Trio system at a recent Stereophile Show. Svelte Shelves were applied to the active subwoofers, and the 3-way horn assembly were placed on Ultra Platforms. Jim is a fan of Symposium equipment and uses Ultra Platforms under his Trio system at home. Trio owners find that Symposium platforms under their Trios improve coherency, dynamics and bass clarity; for some unsolicited comments from happy Trio owners, please click here.
