Agree with Viridian's advice. The NAD is a solid performer and works well with your table--when you upgrade a component like that you risk having it expose weaknesses in the turntable/arm that might ultimately lessen your enjoyment. I would not change an arm or a platter on a table like this, unless, in the case of the latter, you want a different sound (acrylic, in my experience, might sound a little less lively, and if you want that the mat might be the cost-effective way to go). Just my $.02.
