Why? Is the motor isolated inside the pod?

WM, the best decks I have heard are the SME 30 and the Blue Pearl. The Vpi HRX is also outstanding in some ways but I found it lacking in others/

I cannot comment on  the BL as I only have 3rd party opinions at the moment. If it is anything like the Simon Yorke however, it will have wonderful bass and dynamics, but be seriously lacking in other areas such as soundstage layering and image depth in comparison with the references mentioned above. Of course this could be addressed by providing proper support for the Yorke, but at a cost that makes it very poor value for money compared with the Vpi and SME.
