主なアップグレード点
Nearly 90% Lower Measured Ripple
Under controlled bench conditions, the stock PSU measured 21.13µV ripple at no load and 32.09µV under full load. With LPS-T8 installed, ripple measured 2.577µV at no load and 3.556µV under full load, representing approximately 87.8% lower ripple at no load and 88.9% lower ripple under full load. This gives the T8 a quieter electrical foundation.
LHY AUDIO 手作業製作のトロイダルトランス
The latest LPS-T8 uses an LHY AUDIO hand-wound shielded toroidal transformer instead of a standard industrial transformer. It features a 0.27mm high-flux silicon steel core rated above 19,000 Gauss, 6N OFC primary winding, 7N OFC secondary winding, sealed high-purity copper-foil shielding, and layered vibration damping. Each transformer is verified under a 12-hour full-load test, with output consistency controlled within ±0.5%.
AC 入力経路の改善
The original relay-based automatic voltage switching is replaced by a manual 110V / 220V terminal jumper. This shortens the AC input path, reduces relay contact points, and helps improve long-term connection reliability.
専用 EMI 入力フィルター
The EMI board uses an advanced two-stage filter design with RIFA X2 / Y2 safety-rated capacitors and dual large OFC-wound toroidal common-mode chokes, reducing line-borne interference before power conversion.
低ノイズ DC 電圧制御段
The DC regulator board uses LT4320 ideal full-wave rectification, ADI LT3042 ultra-low-noise linear regulation, and PNP current boosting. Filtering is handled by Nichicon KG 10,000µF / 50V ×4, Nichicon FW 1000µF / 25V ×12, and WIMA 0.1µF / 1000V ×3 film capacitors. A 2.0mm PCB, 2.5oz copper, immersion-gold finish, and WBT solder further support lower impedance and stable current delivery.
試聴の感想
Typical owner feedback includes a quieter background, clearer low-level detail, better separation, cleaner bass stops and starts, and smoother vocal texture. Final results will vary with the system, cables, music, placement, and room conditions.
