5 Years of Serenity

Over the past 5 years Stack Audio has been developing and selling upgrades for the iconic LP12 turntable – The SERENE range.

SERENE II starts a new chapter for Stack Audio following an extensive two-year development programme. With SERENE II we have raised the bar with a new and expanded range of upgrades focused on retrieving even more musical detail from the LP12. 

Precision & Rigidity

The LP12 has been around for nearly 50 years  and not all LP12s start from the same place when it comes to precision. SERENE upgrades can be fitted to any LP12, significantly enhancing precision and rigidity in both the structural and suspended parts.

All musical information is picked up as vibrations from the stylus acting in the groove. The bumps and dips in the groove are at a micron level (a one millionth of a metre) and retrieving every micro detail counts in recreating the musical performance. By the application of precise tolerances, the SERENE upgrades enable the stylus and bearing to perform at their best, revealing a level of musicality that was previously masked. The rigidity and strength of all the SERENE components ensures the tolerances are maintained throughout a lifetime of use.

At Stack Audio we drew inspiration from the natural world – hexagonal patterns are prevalent in nature due to their efficiency in providing a perfectly rigid structure. The carefully designed hexagon structure on SERENE Alto and Soprano sub-chassis and armboards provides extreme rigidity whilst maintaining the crucial centre of gravity and balance the LP12 requires.

The LP12 is a suspension-based system where the correct centre of gravity is crucial to the balance of the suspended components. SERENE sub-chassis and armboards are carefully designed to ensure this balance is maintained, no matter which upgrade you choose.

Good Vibrations

Vibrations in turntables occur as feedback into the structure and from internal components like motors. Managing vibrations in the LP12 involves dissipating that energy as quickly as possible avoiding dampening where musicality is lost. 

This is where Stack Audio’s Advanced Vibration Dissipation Compound (AVDC) technology comes in. Our goal was to keep the character of the LP12 whilst enhancing the performance by the careful dissipation of masking vibrations. We use AVDC in engineered inserts in key components to remove vibrations evenly over a wide frequency range. This avoids upsetting the harmonic relationship of each component of the turntable and ensures we maintain the LP12’s classic rhythm and timing.

The result is audible: more detail, a deeper, sharper bass and a more coherent sound stage. All whilst retaining the core sound and character of the LP12.

The Making of SERENE

I brought my LP12 because I like the way it sounds. I don’t want to change the character so why should I go for the Stack Audio upgrades?
Our customers frequently tell us that the SERENE upgrades retains the same tonality, yet they hear much more detail. This was our core goal – the iconic LP12 sound with more transparency.
The 90-day money back guarantee is great, but I can’t hear the upgrades before I install them. How can I try before I buy?
Yes, installing the upgrades is time consuming especially if you decide afterwards to remove them and reinstall the original parts. In the UK some of our dealers have demonstration systems. On this website we try to describe the sound through independent reviews and customer testimonials. An easy way to sample the upgrades is to buy one of our baseboards. It is very simple to install and gives you an insight into the sound and benefits of the all upgrades. The way they work is the same for each component so you get cumulative benefits as you fit more.
I have no authorised installer near me, what shall I do?
Send us an email with your post code; have a database of experts who have worked with hundreds of LP12s. It may be that we can arrange help from another dealer near to you.
