在Hi-End音響系統中，電源線材絕非配角一職，而是聲音表現的起源。Monitor Acoustics這麼多年來，累積了超過200套的完整電源系統升級案例，深知高端玩家對於電源品質的嚴格要求。就在首款採用「中空速導」技術的HU-220 MKIII成功之後，便在心中萌芽HU-165MK III的開發，懷抱著對聲音還原更高標準的信念，開始物色最合適的超低含氧原材，將我們對導體技術與線材聲音哲學的極致理解融入其中，這正是HU-165MK III入戶線的開始。
在開發中期，我們有兩位來自上海的完整電源系統用家回饋，而他們都是使用HU-220 MKIII（首款中空速導設計）作為入戶的第一條線，歷經幾個月的裝潢工程期，最後甫試自家原有完整音響系統後，內心悸動驚艷不已！HU-220 MKIII在「尚未煲熟」的狀態下，就已經與過去的聲音「質感、音色、細節」明顯跳升一大階，聽感展現出高度的空間3D感，與自然的音樂表現，不僅空間音場立體、音色迷人且通透鮮活，自然度與完整性更在短短數日內再次進化提升，完全不需要等待6～8個月的煲機期，聲音的完整性就已一一真實浮現，足以見其傳導效率與音質純度遠遠超乎期待。這樣的回饋，讓我們更加堅信HU-165MK III的開發勢在必行，同時必須更仔細的思考如何去超越HU-220 MKIII，而超純導原料就是我們首要克服的第一個關鍵。
最後，HU-165MK III搶購到一批罕見的超低含氧（2.8ppm）的6N LC-OFC銅導體，設計以34蕊絞繞成一股，集六股捲繞成HU-165MK III的速導核心，線芯截面達16.4mm²，能夠提供極致充沛的導電面積，進一步降低阻抗與能量損失。同時，延續HU-220 MKIII的成功經驗，銅導體以「中空速導（Hollow Air Cable Design）」技術作為設計核心，在線芯中心留了一道中空通道，讓導體中心形成一道自然氣流通道，利用溫差變化排出因電流與磁場交互所產生的熱量，有效平衡溫升、延長線材壽命，並維持導電表面的穩定性，提供極淨的導電通道，提升導電速率。玩家若在此就注意到這個細節核心，最終將能獲取到寂靜的背景底噪，與超高能量的鮮活動態，這前段的投資絕對值得列入優先選項。
而在HU-165MK III的防護層上，採用了五重屏蔽結構（含三層高介電塑料與兩層金屬），由內而外的塑料隔離絕緣層，選用高介電性能的鐵氟龍、半硬質PVC與高性能彈性體TPV塑料，其中最外層更指定選用台灣本土材料「高性能TPV」，介電特性優於PVC超過一倍，耐溫範圍高達-55°C至135°C，壽命可達20-30年以上，而且優點還不止這些，我們更在塑料中加入了多樣奈米微量元素，強化性能表現，有效強化抗老化性與電場穩定度。兩層金屬防護則提供了優異的抗EMI/RFI干擾能力，尤其適合在雜訊密度高的都會區或是複雜供電環境的大型社宅中使用，這些細節中盡露了我們對材料、介電、屏蔽、制振的極致要求。
我們在產品的規劃、銅材導體、製程優化的選擇上，始終堅持著自源頭篩選最頂級原料，就算要等待排產與製程優化的調整，都不厭其煩的反覆試驗做至最好，這都是為了確保聲音的純度與穩定性。即使在製造成本無法量產化的情況下，我們仍堅持開發這條「超越標準、只為音質」的頂尖之作。
HU-165MK III不僅是入戶電源專線，更是一條開啟Hi-End真實感知的入門鑰匙。

HU-165MK III Single-Core Insulated Power Cable
The Next Evolution of Hollow Airflow Conduction — Forged from Ultra-Low Oxygen Copper to Power the Heart of Your System Upgrade
─────────────────────────────────────────────
In any high-end audio setup, power cables are far from secondary — they are the starting point of sonic expression. At Monitor Acoustics, with over 200 complete power system upgrade cases under our belt, we understand the uncompromising demands of audiophiles when it comes to power delivery. Following the success of our first cable to feature the "Hollow Airflow Conduction" design — the HU-220 MKIII — the concept for the HU-165MK III was born. It stems from a vision: to push fidelity even further through conductor innovation, beginning with the purest, ultra-low oxygen copper available.
During development, we received valuable feedback from two users in Shanghai who integrated the HU-220 MKIII into their full power systems as the primary incoming line during their renovations. The results? Even before burn-in, they experienced a transformative jump in sonic texture, tone, and detail. The soundstage became more dimensional, the music more organic and alive. Within days — not months — the HU-220 MKIII had already reached a level of performance that surpassed expectations. This was proof: our hollow conductor technology was not only viable but essential.
With the HU-165MK III, we secured a rare batch of 6N LC-OFC copper with an exceptional oxygen content of just 2.8ppm. This ultra-pure conductor is precision-twisted into 34 strands per bundle, six bundles coiled into one high-performance core, delivering a massive 16.4mm² of cross-sectional area. The result? Remarkably low resistance and minimal energy loss — a robust foundation for current flow.
At the heart of the design lies our signature Hollow Air Cable Architecture — a central air channel carved into the core. This cavity acts as a passive thermal release system, equalizing internal heat caused by electrical and magnetic interactions. It stabilizes surface conductivity, enhances current transmission, and extends cable longevity. This unique detail directly contributes to a lower noise floor and vibrant, dynamic energy — the kind of performance that makes this investment essential for serious listeners.
To safeguard this signal purity, the HU-165MK III features a five-layer shielding system:
-
Three dielectric insulation layers made of high-dielectric PTFE (Teflon), semi-rigid PVC, and a premium TPV elastomer (white/orange)
-
Two metallic layers: copper shielding wires and advanced copper foil tape
The outermost TPV layer — sourced from high-grade local Taiwanese material — delivers dielectric strength exceeding PVC by over 100%, with thermal resistance from –55°C to 135°C and a lifespan of 20–30+ years. We further enriched the plastic blend with nano-scale trace elements for enhanced anti-aging, electrical field stability, and long-term mechanical integrity. The dual metal shields ensure outstanding EMI/RFI protection, making this cable particularly ideal for dense urban environments or complex power systems in multi-unit dwellings.
From conductor selection to process optimization, every step in the HU-165MK III's development was guided by one principle: no compromise for sonic purity. Even with limited production capacity and rising material costs, we committed to creating a power cable that goes far beyond commercial standards — built solely for performance.
The HU-165MK III isn’t just a power entry cable — it's the key that unlocks the door to true high-end sonic immersion.
