PDF 安裝指南
Download the official guide before installation and follow the screw sequence, wiring map, and final safety checks step by step.
Measured Under Controlled Bench Conditions
Ripple noise performance is verified with a dedicated bench setup and then reported under idle and full 2A load conditions, so the upgrade can be evaluated by measured electrical behavior as well as listening impressions.

測試平台配置
The measurement setup verifies the upgraded power path under controlled input, load, and probing conditions before the ripple results are reported below.
原廠電源與 LPS-T8 的漣波雜訊比較
Lower microvolt ripple means cleaner current delivery and a darker electrical noise floor.
| 比較項目 | 原廠 Eversolo T8 | LHY Audio LPS-T8 | 結果 |
|---|---|---|---|
| 漣波雜訊 | Factory PSU reference: 32.09µV | 3.556µV even under full 2A load | Approximately 89% lower ripple than the stock reference. |
| 閒置雜訊底 | Stock switching architecture leaves more residual ripple. | 2.557µV static ripple at idle. | Cleaner background before playback begins. |
| 負載穩定性 | Higher ripple rises against the upgraded linear supply baseline. | Maintains microvolt-level noise at full 2A load. | Stable current delivery with stronger dynamic headroom. |
