In an earlier report, an audiophile with an unrelenting pursuit of sonic excellence purchased a PEAK Sonora two-way floor-standing loudspeaker, Chord Company’s flagship ChordMusic speaker cables and Jumpers, the near-flagship SarumT RCA interconnects, and the PhonoARRAY turntable grounding system at the Wan Chai showroom—assembling an audio combination that many would envy. Not long after, this same client returned with a request for further upgrades, seeking to realise the ultimate configuration in turntable grounding: the Dual PhonoARRAY Grounding Method.

At the core of this upgrade was the addition of a second PhonoARRAY grounding unit and a one-metre Shawline professional grounding cable. Building upon the original setup, in which a PhonoARRAY was connected between the turntable and the external phono stage, the client installed an additional PhonoARRAY at the grounding junction between the external phono stage and the preamplifier. This “Dual PhonoARRAY Grounding Method” is regarded as the optimal state for turntable grounding—capable of further eliminating subtle noise interference and elevating signal purity to new heights.

It is worth noting that the client’s vinyl playback system also underwent significant enhancement, with the original turntable model replaced by a higher-spec Vertere turntable. The phono stage was upgraded from a built-in circuit within the preamplifier to a standalone external unit, substantially improving the focus and performance of the phono amplification circuitry. The combination of a comprehensively upgraded vinyl system and the Dual PhonoARRAY Grounding Method has made the entire playback chain “a soaring dragon with strengthened wings, ascending several more storeys”—achieving the ideal state long envisioned by the discerning enthusiast.

During the post-upgrade listening session, three LPs known for testing system performance were selected:

Singing Opera – to examine vocal presence and spatial reproduction.
The Case Is Closed (審死官) – to assess separation and dynamic response in complex musical scenes.
Rossini – to scrutinise the delicacy of classical music and the textural authenticity of string instruments.

Listening impressions confirmed that the Dual PhonoARRAY Grounding System further reduced the noise floor, rendering the sonic backdrop more tranquil and profoundly silent. Minute details emerged with enhanced clarity, and dynamic contrasts grew more vivid. This upgrade was not merely an addition of components; it embodied the audiophile’s relentless pursuit of perfect musical reproduction. The evolution from single-point to dual-point grounding parallels the structural refinement from single-point support to dual-point stability—underscoring the timeless audio truth that “the devil is in the details.”

The client expressed that this upgrade brought his vinyl system to an unprecedented level of purity and musical engagement—every investment tangibly justified by the audible advancement in sound quality. As the vinyl renaissance continues to flourish, such unwavering dedication to ultimate playback fidelity is charting a new direction in high-end audio culture.
