Sistrum Platforms Apprentice 3 platforms

I have for sale 3 Sistrum platforms.  The first one (the Apprentice) has 1" audio points on one side and 1.5" audio points on the opposite side. The other 2 platforms were part of the original test platforms used to develop the Sistrum line.  These 2 platforms are perfect for large speakers AND amplifiers.  They come with 2" audio points on both sides---  their dimensions are 28.25"wide X 20.75"deep. I am the original owner and purchased these from Robert at Sistrum approximately 4 yrs ago. If you are unfamiliar with Sistrum please check out their website for all the benefits that these platforms generate(they are real and you will be amazed).  There are also many reviews to be found on these as well(all POSITIVE), and tons of positive comments in the forums here on Audiogon. My price includes shipping & paypal. I prefer to sell all 3 as a package. Thanks for looking!
