On a previous setup I was using the Super Rectifier on one of his phono stages. Memory fails as to which one. The Super Rectifier is money well spent. You will not be disappointed. His gear is top notch.

I had a chance to listen to this and was extremely impressed for those who also may be curious like I was. I'm not sure how these devices can do this but I can certainly hear the differences, it's not subtle.
Happy listening,
