Stack Audio’s aim with the SERENE LP12 upgrades was to enable secure fixings and permanent alignment between the sub-chassis and separate arm boards. To overcome the issue with the simple self-tapping screws in the standard MDF arm board, the SERENE Arm Boards are made from Solid Surface and use threaded metal inserts. These ensure that the arm board has a secure connection with either a standard sub-chassis or the SERENE Sub-Chassis. The SERENE Arm Board can be removed and re-attached without deteriorating the thread and compromising the long-term quality of the connection. The underside is hollowed out to ensure a perfect centre of gravity and minimal but secure contact with the sub-chassis.   Like all SERENE components, vibration dissipation is a key part of the design. Removal of the vibrations at final point of contact with tonearm ensures the SERENE Arm Board lets your preferred arm reveal more detail and more focus. Reflecting their musical performance, SERENE LP12 Arm Boards are polished to a high gloss piano black finish.

If simply attaching a SERENE Arm Board to an existing sub-chassis this can be done without dismantling the LP12. The baseboard will have to be removed and the arm cable and mounting detached. After fitting the new arm board the suspension will have to be re-checked for height and bounce.   If a SERENE sub-chassis is being installed at the same time more extensive. Replacing the sub-chassis requires the removal of the baseboard, cross-brace and arm/arm board (see separate installation instructions).
Robert J (USA): Arm Board The first thing that becomes instantly apparent on receipt of the Serene arm board, is that the exceptionally high quality of its finish and functionality has been the primary focus in its design and build, from its inception to the final product the love of the music has shone through. The three brass inserts allow a faultless connection between the sub-chassis and the arm board, bettering many offerings at up to five times this price point, and dare I say it, giving some well known extremely high end one piece solutions something to think about   With many LP12 upgrades of this nature the overall dynamics of the sound improvements are often subjective and easily overrated, however on this occasion I believe you can instantly experience a vast improvement over the original arm board.   Further Upgrades   Combine the SERENE Arm Board with Stack Audio’s SERENE Sub-Chassis. Additionally, a SERENE or ULTIMATE Base Board is a very simple installation which you can do at the same time – the baseboard has to be removed to gain access to the arm board fixings. All Stack Audio LP12 upgrades are designed to remove vibration and the benefits are cumulative.
