Soulines tt9 – a Turntable Designed Using the Fibonacci Sequence and the Golden Ratio

Serbian company Soulines has unveiled the Soulines tt9 turntable, which borrows its technical solutions from the flagship Soulines tt42 model. Vibration control was a priority during development, and as a result, the design was calculated using the Fibonacci sequence and the golden ratio. As a result, the company promises minimal resonance and an open, natural sound.

Rather than looking at the components of a turntable separately, Soulines strives for perfect synergy, where all the parts work optimally together. To achieve this, each platter, bearing, and spindle are machined individually rather than produced in batches, with all aluminum parts CNC-machined from solid billets, and each component machined and inspected by hand.

The Soulines tt9's lightweight yet rigid chassis effectively resists resonance, while the inverted main bearing (made from stainless steel, brass and Delrin) ensures stable and quiet operation. The turntable's 30 mm thick, 2.5 kg acrylic platter features an LP "apple" recess, allowing records to lie perfectly flat, and a clamp is included for additional stability. The Soulines tt9's DC motor drive system features electronic speed control, while the robust aluminium plinth provide reliable vibration isolation and resonance control.

As an option for the tt9, Soulines offers the KiVi M3 unipivot tonearm, designed to minimise resonance and maximise groove tracking accuracy. The KiVi M3 features an integrated unipivot bearing, which combines low friction with added rigidity. A one-piece support fork and tonearm tube improves structural integrity, while a versatile counterweight system accommodates a wide range of components. In addition, Soulines offers a range of vibration control accessories, including BBS ball bearing decoupled feet and the U-Base, an aluminium and stainless steel isolation platform.

The recommended retail price of the Soulines tt9 turntable with the KiVi M3 tonearm (including acrylic dust cover and record clamp) is £3,990. The Soulines KiVi M3 tonearm is available separately for £2,090.
