East End Hi-Fi are authorized dealers for Symposium Acoustics, and we are selling a brand new Symposium Acoustics Ultra Platform in any choice of size from 9x14, 19x14, 19x18, 19x21, 19x24, 27.5x21.5. The pricing reflects the 19x14 size.
The Ultra consists of a multi-layered design (right) of varying density materials. But what’s different about Symposium constrained-layer construction is that we have arranged the density of these layers in a specific order, from dense (metal top) to less dense, and then back again. The idea here is to gradually change density in steps, in the same direction, so that energy may penetrate more easily through adjacent layers. This unique but essentially simple design achieves optimal energy drainage from both the component side AND the support (bottom) side at the same time. This "dual direction" absorption provides effective isolation without eliminating the advantages of good energy drainage, and does it without introducing any mechanical "reactances" which are caused by materials which store and release energy, such as sorbothane and other rubber products. Instead of behaving like a reactive load, the design is more resistive, which means it is resonance-free, adding no colorations to the component’s sonic "character" in attaining its goal of reducing noise and distortions in the components it treats.
John Crossett of Soundstage said:
"The quiet quotient was ratcheted up another notch or two, and the clarity of instrumental lines was much greater."
"With the Ultra Platform under the power amp, I could follow whichever section of the orchestra I chose, and as far as I wanted."
"Sounds soft to loud, and the individual shading between those points, were improved thanks to the Ultra Platform."
"I can’t say for sure if the Ultra Platform added any additional extension to the bass I was hearing -- my Maggies only go down to about 40Hz -- but it sure seemed to. I do know the texture and clarity of what I heard was improved. Paul Chambers’ bass line at the beginning of Kind of Blue [Classic Records/Columbia CS 8163] was much easier to follow and had better definition."
"The Ultra Platform’s ability to increase the perception of air, detail, dynamics and smoothness was illustrated to me playing the LP version of Carmen McRae’s Carmen Sings Monk [RCA/Novus 3086-1-N]. The live cuts, especially, were more enjoyable thanks to a better appreciation of the size of the venue where this concert was recorded (The Great American Music Hall)."
"In comparison to what I have been using to control vibration, the Symposium products were distinctly better. None of my admittedly homemade sandboxes could control and dissipate vibration with anywhere near the success of either the Svelte Shelf or the Ultra Platform, together or separately. It wasn’t even close. The Symposium products took what had been a very enjoyable system and ratcheted things up into a more lifelike one, and that’s what I want out of my system."
"They will (Symposium products), however, allow any piece of equipment with which they are used to reveal itself more fully for what it is. They remove veils, clean the sonic window, shine more light onto the music, focus the proceedings, and do whatever any other audio cliché you choose to use indicates."
