2024是MA量子進化的爆發年，在這兩年除了工廠設備的更新、電鍍工法的升級，新材料加入的改變、製做流程的精進，都讓這一兩年推出的產品，性能、效能大步躍進，就連外觀也都變得更加亮眼。而這次小改款的Studio Class，就是以新一代的材料、電鍍與製程來生產，高密度的電導系統，產生了高密度的表現力，10KAw的爆發，成就結實的基礎，同時讓人感覺到能量充沛、源源不絕。
這回改款升級的75A版本，是專為給大系統、電需求量高的玩家來選用，將內部的開關閘升級為與STUDIO III相同，雖然同樣都是75A，但製程細節完全不同，就算系統用上一對怪物級單聲道擴大機、或是高耗電的真空管系統，爾或是數位、類比音響系統同時工作，都能游刃有餘的灌輸最快速即時、飽滿充沛、醇靚純淨的端正電源，給予音響系統源源不絕的強大靚電能量。此外，機箱內部元件這回部份也改用新材料與新的製程，其中作為箱內隔離與抑振的第一道防線，就是「機箱底板」，新材料選用新一代的高精純厚銅板，並在表面施以髮絲細紋處理，最後再噴上特殊透明漆面，一方作為調音使用、二方面預防銅質氧化、產生質變，以此打好基底，作為堅實隔離的第一道防線。
這次水、火、地的銅導板，也改採新一代的高導優質銅材，厚銅板先經過CNC、慢速研磨、超音波淨化、電子級奈米量子電鍍，最後再送去長時間超低溫-196°C冷凍處理。而這單單一片的銅板元件，就是需要這麼多的製程步驟，其半永久性的穩定條件，為的就是確保銅金屬物理條件，達到最佳的高電流、高速度與耐高電壓的傳導特性，展現出極為優異的電源傳輸性能，表現出不凡的全方位導電能力。而同樣的材料、工法也用在G相（地線）上，只不過這回接地板略為小改款，接駁端子數改為7個，並在螺絲處理的技法中，加入了一些秘技變化，為的就是讓電位差能更加快速的釋放，讓聲音的表現更為鮮活靈動、立體鮮明。
MA靜神的隔離抑振電箱，內外部件全都採用訂製組件，箱體採用厚鐵鍍鋅、並覆以特殊高溫烤漆處理，給予隔磁、抑振、穩固的基石，內部的無熔絲斷路器，從外觀看來雖與市售相仿，但我們做了一些優化的工程，以絕對高品質工藝加工，讓過電表現更加優異，MA靜神用以嚴苛標準就是為了精益求精；加上我們的協作廠商，其技術與製程工藝都可依需求要求、且支援度高，再複雜的工序都能搞定，同時強化高規結構製程封裝，就算在持續不斷的大電流經過時，也能夠完全隔絕電磁輻射與弱電的干擾，確保高介電值、耐大電流電壓的高效性能，完整傳輸出極大化的電能頻寬。
MA靜神歷經長時間的開發研究，專注於精確的音響電源這領域，我們精進修行市電處理技藝，將別人做不到的極寬頻，透過「MA靜神電源系統」重新展現，這是市面上常見的拼裝電源所達不到的境界，而MA靜神堅持的每個關鍵環節都不能錯放，最終才能擁有豐潤、飽滿、充沛、純淨的寬頻電能。MA靜神一直追求著自我的極限，旗下隔離抑振電箱經歷了數代的演進，採以最完善、完整的線路佈局，加上精良且特殊的零組件，將入戶電能作第一道的醇化處理；玩家還能選購MA靜神的「超級接地器（ Evolution / Studio / Basic ）」、「複合地迴接地板（ M-460/440 ）」，更能讓接地的性能翻倍躍進，這同時也是淨化電源的重要核心之一，我們強烈建議「進入室電的第一步」千萬不容小覷，別讓拼裝車在一開始就虛化了電源能量，選擇MA靜神電源系統，將是您翻轉平凡電源的第一步，極致音響電源的無限可能從此開始。

MA-PB75A-5 Studio Class Isolation Power Block
Minor Update. Major Leap. Power Simplified, Performance Amplified. Welcome to Pure Power.
────────────────────────────────────────────
2024 marks the breakthrough year of Monitor Acoustics’ quantum evolution.
Over the past two years, upgrades in factory equipment, plating techniques, and the integration of new materials and refined production processes have fueled remarkable advancements in our products — not only in performance and efficiency, but also in design and visual appeal.
This newly refreshed Studio Class Isolation Power Block is built using our latest generation of materials, electroplating, and fabrication methods. The result is a high-density power conduction system capable of delivering explosive performance — 10,000A surge resistance with rock-solid stability — while maintaining a constant flow of dynamic, rich, and clean energy.
The upgraded 75A version is tailor-made for high-demand reference systems. Featuring the same internal switching gate as our flagship STUDIO III, this unit may still be rated at 75A, but it’s built with entirely different production techniques. Whether you're powering a pair of monster-class monoblocks, a power-hungry tube amp, or running digital and analog gear simultaneously, the MA-PB75A-5 delivers fast, full, and ultra-pure power — effortlessly and endlessly.
Internally, we've upgraded critical components with brand-new materials and cutting-edge processes. The first line of isolation and vibration suppression is the chassis base plate, now made from next-gen high-purity thick copper, treated with a brushed finish and coated in a protective transparent lacquer. This not only prevents oxidation but also fine-tunes resonances — providing both sonic refinement and structural integrity.
We’ve also reengineered the water, fire, and earth phase copper conductors, now crafted from ultra-high-conductivity copper. Each thick copper plate goes through CNC machining, slow grinding, ultrasonic cleaning, quantum-level nano electroplating, and finally, an extensive deep cryogenic treatment at -196°C. This painstaking, multi-stage process ensures semi-permanent metal stability, enabling optimal performance under high current, high speed, and high-voltage conditions — delivering extraordinary power transmission and conductivity.
The grounding conductor (G) uses the same material and techniques, but with a subtle redesign. Now featuring 7 connection terminals, we’ve also enhanced the screw contact treatment with proprietary adjustments to improve voltage potential release, resulting in a more vivid, spacious, and lifelike soundstage.
The entire MA-PB75A-5 is built from the ground up using custom-made components. The chassis is constructed from thick galvanized steel with a high-temperature baked coating that provides superior magnetic shielding, anti-vibration properties, and rugged durability. The built-in circuit breaker may look similar to off-the-shelf types, but it’s been internally reengineered with precision craftsmanship to exceed standard performance, reflecting Monitor Acoustics’ relentless pursuit of perfection.
What sets us apart is not just what we make, but how we make it. Our trusted partner manufacturers offer flexible, high-precision processing capable of tackling even the most complex production demands. The result? Reinforced structures that maintain peak dielectric performance and immunity to electromagnetic and low-voltage noise, even under continuous high current loads.
With decades of research and refinement behind it, the Monitor Acoustics isolation power system is not your average off-the-shelf power strip — it’s an uncompromising solution purpose-built for wide-bandwidth, high-resolution power delivery. Every critical detail is obsessed over. The result? Rich, powerful, full-bodied energy transmission with unmatched clarity and depth.
MA-PB75A-5 isn’t just a power block — it’s the foundation of your high-end audio system.
To take performance even further, we highly recommend pairing it with our Super Ground Units (Evolution / Studio / Basic) or Hybrid Grounding Modules (M-460 / M-440) for an exponential boost in grounding effectiveness. Proper grounding is a core principle of power purification, and the first step into your listening room should never be taken lightly. Don’t let DIY-grade solutions compromise your system from the start. Choose Monitor Acoustics and transform your power — and your music — from ordinary to extraordinary.
