Per PM, try the Ultra 5s and the Magico QPods. I still have the original Stillpoints+granite+sorbothane+EAR Isodamp under the turntable and the Isodamp+granite+felt under the speakers. You really have to fit hard on the rack to hear feedback from the TT, and the floor no longer sings along the speakers - the energy is focused on the speakers' woofers, very significant improvement. I bet the Magico device is the better option.
Thank you!!! Very interesting and will speak to dealer about both.
