Greenstreet Audio subchassis aka 'Keel Klone' for the Naim Aro tonearm and Cirkus bearing. CNC milled in one piece from billet 6160 aluminum and hard anodized in black. This came off my personal one-owner 'table and the cosmetics of exposed surfaces is excellent. compared side by side with an actual Keel the differences are VERY subtle, sonically its an unqualified success at a fraction of the cost. Custom Linn logo applied after much toil. PM with any questions. Shipping is at buyers sole cost and expense. The Naim Aro tonearn has sold.
