AIDAS TRU STONE VIOLET GOLD
A high-tech stone model that fuses the beauty of gemstones with the resonance of pure gold.
Product Concept
The "TRU STONE VIOLET GOLD" adds a completely new acoustic approach to the lineage of AIDAS's top-tier "AU Series (24K Pure Gold Coil)."
The body uses the high-tech composite material "Tru-stone," which combines the beauty of natural stone with vibration-damping performance. By combining this with the highest purity 999 pure gold wire, it brilliantly balances the unwavering serenity unique to stone bodies with the rich harmonic expression created by the pure gold coil. Both visually and aurally, it is truly a masterpiece worthy of being called a "gem."

Body Material: Acoustically engineered artificial stone "Tru-stone"
■ Ideal vibration control exceeding natural stone
"Tru-stone" is an extremely high-density high-tech material reconstructed from natural mineral powder using a special resin.
- Thorough elimination of resonance: Pure natural stone sometimes possesses sharp inherent resonances, but Tru-stone maintains the stone's "hardness and mass" while also incorporating the resin's "moderate internal loss." This instantly converges the minute unwanted vibrations generated by the generator mechanism, realizing an extremely modern and clean background (S/N ratio).
- Elegance of Violet Gold: With gold particles sprinkled within a deep violet color, its appearance satisfies the desire to own it as a craft piece beyond the realm of audio equipment.
Technical Features: Supreme resolution brought by pure gold coils
1. 24K Pure Gold Coil (999 Pure Gold)
Uses ultra-fine 0.04mm 24K pure gold wire. The supple and expansive highs unique to gold wire and the profound spatial reproduction cannot be experienced with other metal materials.
2. Unique shape enabling shortest transmission
The unique protruding shape of the AIDAS front is designed to position the connection pins as close to the coil as possible. To maximize the effect of the pure gold coil, the signal path has been shortened to the extreme.
3. The Crystallization of Japanese Precision Jewelery Technology
The cantilever uses highly rigid boron, and the stylus features micro ridges. Parts made by Japan's world-leading precision manufacturer 'Adamant Namiki' capture every bit of information engraved deep within the grooves.
A Unique Form Born from Function: Acoustic Benefits of Its Original Shape
The distinctive silhouette of the AIDAS cartridge is not merely for visual differentiation. Its shape arises from the 'acoustic necessity' of placing the connection pins close to the coil and shortening the signal path to the physical limit. Additionally, each body is manually machined to maximize the 'specific vibration-damping energy' of rare materials such as mammoth ivory and natural stones, achieving a high-level fusion of visual beauty and overwhelming acoustic performance.
AIDAS: Mounting Style and Compatibility
-
Bolt-On Thread System
The AIDAS cartridge body features precise threading (M2.5). It can be mounted smartly from the top with only a bolt, without using nuts, greatly reducing installation stress when handling expensive cartridges. -
Half-Inch Mount
Uses the global standard 12.7mm spaced screw holes, compatible with head shells from various manufacturers, making it a highly versatile design. -
Optimization for Tonearms
The balance of weight and optimal tracking force is optimized to allow AIDAS to fully perform on many modern "medium-mass tonearms." -
24-Karat Plated Pins
The output pins are brass with 24K gold plating. They resist oxidation over time and maintain signal fidelity at the lead wire connection for long-lasting performance.

Global Audiophile Acclaim: Sound quality recognition recognized around the world
Positive Feedback publication review
Aidas Cartridges TRU STONE VIOLET GOLD in the long-established American audio magazine "Positive Feedback"has been published with highly rated reviews. In addition, reviewer Robert H. Levi also highly praised Mammoth Gold in the same magazine, and is a die-hard Aidas fan who declares, ``My reference cartridge is Mammoth Gold.''
The reviewer listened with an ultra-dreaded system: E.A.R. Disc Master turntable (limited to 7 units in the US), Helius Omega tonearm (silver wire specification), Zesto Allasso step-up transformer, and E.A.R. 88PB tube phono stage. After several months of thorough comparison with Mammoth Gold, he evaluated it as ``a killer cartridge that has 90% of the performance of Mammoth Gold overall,'' but also said, ``In terms of imaging, it may be on par with Mammoth Gold.''
Regarding the low frequencies, it is described as 'filling the entire room with gut punching.' In the IMPEx record organ recording, it was highly praised for 'shaking the room with layered resonance and resolution unlike anything heard before.' It is reported that the violin and reed instruments were reproduced sweetly and lustrously, and the vocals were warm and accurately reproduced. Additionally, it is noted for never being improper even with musically unremarkable LPs, and for the remarkable depth of character that allows any record to sing honestly and gracefully.
The essence of this device is summed up as follows: 'The imaging is top-level, and the depth of the sound stage is the same. The width is grand and dramatic. Despite the enormous sound, it is natural and never harsh or improper. Each LP sang honestly and gracefully. There was never a dull moment.'
This is a common impression held by many enthusiasts, transcending individual opinions.
'Reality created by ultimate silence'
'The effect of the Tru-stone body is tremendous. The "intrinsic resonance" commonly seen in general wood or resin bodies is completely eliminated. The moment when the refreshing treble unique to the pure gold coil rises sharply from the jet-black background is a pleasure that can only be experienced with this cartridge.'
'Analytical yet musical'
'While possessing a monitor-like characteristic that depicts even the finest details with precision, it also embodies the "warmth" and "supple quality" brought by the pure gold wire. It is rare to find a model that achieves both high resolution and luster, especially in the texture of string instruments and female vocals.'
'Solid and stable low frequencies'
'With an appropriate weight of 11.8g and thanks to the Alnico 5 magnet, the energy density of the low frequencies is very high. The foundation of the orchestra is firm, giving a sense of security that the stylus perfectly governs the grooves in any complex composition.'
