主要升級重點

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 手工製作環形變壓器

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%.

更純淨的交流輸入路徑

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.

專用 EMI 輸入濾波

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.

低雜訊直流穩壓級

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.

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.

Product Name: LHY AUDIO Eversolo T8 Dedicated Power Upgrade Kit

Compatible Model: Eversolo T8

EMI AC Filter Board:
Input voltage is 115V or 230V AC mains. Output voltage is also 115V or 230V AC, manually selectable via an on-board terminal.

Rectifier/Regulator Board:
Input voltage is supplied by the dedicated transformer secondary output. Output voltage is 12V DC.

Ripple Noise:
Measured ripple is 2.577µVrms at no load and 3.556µVrms under full load. Compared with the stock unit, which measured 21.13µVrms at no load and 32.09µVrms under full load, LPS-T8 reduces ripple by approximately 87.8% at no load and 88.9% under full load.

Dimensions:
EMI AC filter board: 115 × 60 × 27 mm.
Rectifier/regulator board: 170 × 72 × 45 mm.

Weight:
0.45 kg for the two-board set. Total kit weight varies depending on transformer and included accessories.

Accessories Included:
6-pin ribbon cable, cross-head screwdriver, hex key, gloves.

Key Performance Metrics:
After the upgrade, ripple noise is significantly reduced. It measures 2.577µVrms at no load and 3.556µVrms under full load, roughly one-eighth to one-ninth of the stock unit’s measured ripple. The output voltage is 12V DC, matching the power requirements of the Eversolo T8. Voltage selection is changed to a manual 115V / 230V terminal, replacing the stock relay-based automatic switching to shorten the AC path and reduce relay contact points.

Component & Process Comparison:
For the rectifier stage, LHY uses an ADI LT4320 high-performance ideal diode bridge, while the stock unit uses MUR860 fast-recovery diodes. For voltage regulation, the upgrade employs an ADI LT3042 ultra-low-noise linear regulator paired with PNP current boosting; the stock unit uses an OPA277 op-amp with MOSFET regulation.

The main filter capacitors are upgraded to four Nichicon KG 10,000µF / 50V capacitors, compared with the stock six 6,800µF / 35V capacitors. The output filter stage uses twelve Nichicon FW 1,000µF / 25V capacitors, supplemented by WIMA film capacitors.

In terms of PCB and build quality, the upgrade features a 2.0mm PCB, 2.5oz copper, immersion-gold finish, and WBT solder. The transformer is an LHY AUDIO hand-wound shielded toroidal transformer with OFC copper windings, copper-foil shielding, and vibration damping.

Professional Test Equipment:
Testing is carried out with professional bench instruments, including electronic load, oscilloscope, precision multimeter, APx525 audio analyzer, and spectrum analyzer equipment, to verify electrical performance under controlled conditions.
