Synergistic Research Tranquility Active Isolation Base - REDUCED PRICE

Original owner; purchased this active isolation base 4 years ago. This is the original 18.5 x 16 inch middle model; not the Basik or XL model. It is not the current UEF model although I understand it also has UEF technology in it. Have used this successfully with a Mac mini and hard drive digital setup. Functions perfectly; cosmetically, it has a few light scratches/smudges that can be made out in bright indirect light, so to be very conservative, I'll rate this 7/10. Included are the 6 MIGs, grounding cable that plugs into an outlet, MPC, original silver and grey enigma bullets and also a grey UEF tuning bullet (the one with ridges on it in the photo) which I purchased separately. I will cover Paypal fee and buyer to cover shipping costs. I will only ship to a US address. P.S. If you have a SR grounding block, I also have a SR high definition grounding cable for the tranquility base that I would be willing to sell for 50% off its list price. Thanks for looking.
