I see. I love the 401, it is a no fuss awesome sounding table when it is correctly sorted. I prefer it to my former GAE primarily because I can easily change arms and there is no SMPS to deal with. The first order of business with these tables is to get a modern bearing into it. Focus will snap into place, the noise floor will plummet but the power delivered by the idler drive is still on tap and present. I did a lot of back and forth comparing the stock bearing with the newer more modern bearings. At the minimum get a Kokomo mk 2 (I think the latest is a Mk 2) but if you can swing it go for the higher end bearings offered by some of the restorers out there. Mine is slated to eventially receive the AF inverted statement bearing/platter.
My SP10 MK3 is my Grail turn table. I listened to the Techdas AF1 recently and that was nice.
