The SERENE Project

  • Two years research and development
  • Five re-engineered components
  • Innovative materials. Precision manufacturing

Serene is a game changing series of upgrades for Linn owners to enhance the organic sound of the LP12, whatever the model, whatever the ageThe result is SERENE. Exceptional upgrades for the LP12.

Whichever upgrade you choose, the objective is the same. The removal of vibrations and colourations within the LP12. A lower noise floor means you hear more detail, more focus and a greater soundstage. Most importantly this means increased ability to follow the tune. Simply put, more musicality.

Our aim has been to develop the highest quality affordable upgrades. Stack Audio doesn’t believe high-end hi-fi always has to come with high-end prices.

SERENE is available as a complete set, staged upgrades or individual components to suit your needs

Core Design Philosophy

The SERENE project is based on a fundamental understanding of the effects of vibration and acoustic resonance on sound quality. A combination of objective analysis using the latest software and subjective listening with independent experts is applied to every product from Stack Audio.

Replay starts with the vibration of the stylus in the groove. Any vibration picked up other than from the groove and the stylus is distortion and this distortion masks detail in the musical signal. This is then amplified by the rest of system. The immediate dissipation of vibration is the primary objective of the SERENE project

Innovative Materials

Solid Surface

We trialled many different materials throughout the SERENE project, but one stood out: Solid Surface. This material is a composite of acrylic polymer, aluminium and minerals making Solid Surface profoundly inert and stable and as a composite resonates significantly less than aluminium, steel or wood and is denser than acrylic alone.

Solid Surface is used in the SERENE Sub-Chassis, Cross Brace, Arm Board, and Base Board.


Advanced Vibration Dissipation Composite

AVDC is used in the SERENE Cross Brace, Top Plate and the optional 3-layer Ultimate feet for the Base Board. This advanced material acts as a laminate, trapping and dissipating vibration immediately by turning it into heat. AVDC is a key part of the system of SERENE upgrades focused on the dissipation vibration within the turntable.


SERENE Sub Chassis

The sub-chassis is the backbone of the LP12 and has been at the core of the SERENE project development. Refined through 3 phases, the SERENE Sub-Chassis is machined from 12mm Solid Surface with a honeycomb shape on the underside that provides maximum structural integrity and even dissipation of vibrations. Varying machined pocket depths ensure this highly complex form has the mass and balance of the original sub-chassis. Improving the performance of the suspended design of LP12 is the aim - enhancing the organic sound of the Linn not detracting from it.


SERENE Sub Chassis

The SERENE Sub-Chassis can be fitted to any LP12 and works with original arm boards as well as SERENE Arm Boards. The combination of SERENE Sub-Chassis and a SERENE Arm Board ensures the vital connection between the sub-chassis and the arm board is assured over time. No loosening of the fixings maintains a rigid base for the arm and the cartridge to do their job. Stack Audio believes that the SERENE Sub-Chassis and the SERENE Arm Boards perform at the very best when paired together.


SERENE Arm Board

Made from Solid Surface with threaded brass inserts, the underside of the SERENE Arm Board is hollowed out to ensure a perfect centre of gravity and minimal contact with the sub-chassis thereby minimising vibration transmission. Removal of the last colourations and vibrations at final point of contact with the tonearm ensures that the SERENE Arm Board allows your preferred arm to reveal more detail with increased focus.

Machined for balance and Performance

Commensurate with their performance SERENE Arm Boards are finished in a luxurious deep gloss piano black.The SERENE Arm Boards are available in 6 standard fittings for Linn, Rega, SME and Naim plus the option of custom fittings for any other tone arm.

SERENE Cross Brace

Stack Audio is unique in offering an upgrade for the Linn cross brace made from 8mm Solid Surface and AVDC with 6 rubber mounts for the power supply. The SERENE cross brace stiffens the plinth and, crucially, isolates vibration from the spindle and motor to the power supply oscillator. The purpose of the oscillator is to control the timing of the motor. Any vibration that reaches the oscillator will alter this timing to the detriment of the performance of the music.

Like the SERENE Sub-Chassis, the SERENE Cross Brace has been refined through 3 phases. A straight forward replacement for the original Linn cross brace, the SERENE Cross Brace comes with all necessary fixings.


Top Plates

Stack Audio offers you a choice of two Top Plates: the SERENE and the ULTIMATE. Both incorporate our AVDC vibration trap, are precision cut to fit flush, and come with all necessary fixings.

SERENE Top Plate

The SERENE Top Plate is made from high grade brushed stainless steel and is a direct replacement for the standard LP12 top plate. The AVDC laminate layer provides dissipation of vibration across the whole surface that has no protection on the standard plate.


The ULTIMATE Top Plate is a sandwich construction comprising the visible top surface and an aluminium frame underneath with an AVDC layer between. The aluminium frame is precision machined on both sides and ensures the top plate sits flush and will never warp.


The ULTIMATE is available in either a beautiful black or silver anodised aluminium finish, or stainless steel for the classic LP12 look. Incorporating AVDC and with 4 extra contact points with the plinth it is more secure with even less vibration than the SERENE Top Plate.

SERENE Base Board

The SERENE Base Board is made from 12mm thick Solid Surface purposely designed to sit flush with the bottom of all LP12s. The Base Board with its large surface area is the first line of defence against external vibrations from loud speakers and other sources reaching the listening room. In combination with the other Serene components it further helps dissipate vibration from within the LP12

The SERENE Base Board has access holes allowing easy adjustment of the suspension springs and bolts without unscrewing the board. Fitted as standard are precision machined aluminium Serene feet with a Sorbothane layer.


ULTIMATE Isolation feet

Available as an optional extra are our new ULTIMATE feet made from wood with four layers of AVDC in addition to the Sorbothane layer It also comprises of two metal parts. Fully adjustable, the ULTIMATE feet provide the maximum level of vibration dissipation between the LP12 and its stand.

    I have just played my first lp. Claude Bolling suite for flute and jazz piano. Absolutely stunning! Bass and mids are superb. The piano sounds like a piano, not a recording of a piano. Gone is any suggestion of wooly or bloated lower octaves. I don’t want to bore you with my catalog of records

    Corian Chassis and Arm board – wow !! what a difference – gone from a fiesta to a ferrari !! -many thanks. Having recently moved house ( downsizing) I was considering rationalising my hi-fi kit . I had a lp12 /circus / lingo 1/ trampoline 1/. which had been unused and in the loft

Structure Set: The SERENE Top Plates, Base Board and Cross Brace stiffen up the rigidity of the plinth, dissipating vibration from external and internal sources.

Platform Set: The SERENE Solid Surface Arm Board and Sub-Chassis are the perfect platform for your tone arm and platter to sit on along with the added acoustic benefit that the SERENE Cross Brace provides through isolating the internal power supply

Full Set: All 5 components of the full set of SERENE upgrades combine to provide the highest level of improvement. The maximum removal of vibrations and colourations within the LP12. The lowest possible noise floor that means you hear more detail, more focus and a greater soundstage. The whole really is greater than the sum of the parts. Simply put, more musicality.
