A100TB - Products

## A100TB: The Evolution of Focus

The "TB" stands for True Balance. While its predecessor, the A100, offered versatility, the A100TB offers perfection. We stripped away the single-ended (3.5mm) circuits to focus entirely on a 4.4mm Fully Balanced Architecture. This streamlined signal path reduces crosstalk to vanishing levels and maximizes channel separation, creating a 3D soundstage that rivals desktop systems.

Laboratory-Grade Components

The A100TB is built with a "cost-no-object" philosophy:

• Vishay Precision Resistors: We utilize aerospace-grade Vishay wafer resistors in the audio path to ensure zero thermal drift and absolute signal integrity.
• Immersion Gold PCB: The circuit board undergoes an immersion gold process to minimize contact resistance and oxidation, ensuring your amplifier sounds as good in 10 years as it does today.

The Power Plant: 6800uF Reservoir

Dynamics require instant current. The A100TB features an upgraded power supply with a 6800uF capacitor bank and an ultra-low noise filter that keeps ripple voltage below 20uV. This "energy reservoir" allows the amp to deliver sudden bass transients with visceral slam, driving high-impedance headphones (like the Sennheiser HD800S) without running out of breath.

The Tuner's Dream: Swap & Expand

• Op-Amp Rolling: Like the Xuanwu and Air, the A100TB features a socketed Op-Amp design. You can easily swap chips to tailor the sound signature to your preference.
• PS100Pro Synergy: On the back, you will find a dedicated power port. Connect the PS100Pro linear power supply to bypass the internal battery entirely, unlocking a new tier of voltage swing and background blackness.

A100TB：專注的進化

"TB" 代表 True Balance (真平衡)。如果說前代 A100 追求的是多功能，那麼 A100TB 追求的就是完美。我們大膽移除了單端 (3.5mm) 電路，將所有資源集中於 4.4mm 全平衡架構。這種精簡的信號路徑將串擾降至不可聞的水平，並極大化了聲道分離度，創造出媲美台式機的 3D 聲場。

實驗室級別的用料

A100TB 的設計理念是不計成本的：

• Vishay 精密電阻： 我們在音頻電路中採用了航太級的 Vishay 晶圓電阻，確保零熱漂移和絕對的信號完整性。
• 沉金 PCB 工藝： 電路板經過沉金處理，將接觸電阻和氧化風險降至最低，確保您的耳擴在十年後依然靚聲。

動力核心：6800uF 能量庫

動態表現需要瞬間的電流爆發。A100TB 升級了電源供應系統，配備了 6800uF 的大容量電容陣列和超低噪聲濾波電路（紋波電壓低於 20uV）。這個「能量水庫」讓耳擴能夠從容應對突發的低頻瞬態，即使驅動高阻抗大耳牛（如 Sennheiser HD800S）也游刃有餘。

調音師的夢想：更換與擴展

• 運放滾動 (Op-Amp Rolling)： 與 Xuanwu 和 Air 一樣，A100TB 採用插拔式運放設計。您可以輕鬆更換晶片，量身定制屬於您的聲音簽名。
• PS100Pro 西裝組合： 機身背面設有專用電源接口。連接 PS100Pro 線性電源後，可完全繞過內部電池，解鎖更高階的電壓擺幅和極致寧靜的背景。
