A100TB - Products
The Aroma Audio A100TB (True Balance) is a fully balanced portable amplifier engineered for absolute sonic purity. By eliminating single-ended circuitry and utilizing a 4-channel symmetrical topology with Vishay precision resistors, it delivers 860mW of authoritative power (at 100Ω). Features a massive 6800uF capacitor bank and a Quick-Swap Op-Amp design for limitless tuning potential.
Aroma Audio A100TB (True Balance) 是一款為追求極致音質而生的全平衡便攜耳擴。通過捨棄單端電路,它採用了 4 通道對稱拓撲結構與 Vishay 精密電阻,提供高達 860mW (100Ω) 的權威推力。內建巨大的 6800uF 電容陣列,並具備快拆式運放 (Op-Amp) 設計,讓您擁有無限的調音潛力。
## 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。
