I would like to introduce a new aluminum body concept for the Denon DL-103.https://www.denonaluminumbody.com
The Aluminum Body Cap provides all of the well documented advantages of other aftermarket bodies available: increased bass presence, improved soundstage and imaging, combined with remarkable tone.
However, all other aftermarket bodies require the stock plastic body to be carefully removed from the cartridge, and most rely on the 'nude' cartridge being friction fit in the body with no mechanical connection to the headshell. Some aftermarket bodies require adhesive potting and adding excessive mass.
The Aluminum Body Cap is not a modification: it is an accessory. The Cap is completely removable, transferable, and greatly reduces the risk of damage to the cartridge. The Aluminum Body Cap securely bolts through the stock cartridge body and headshell, providing a firm, mechanical connection.
Please let me know if you have any questions.
