Laboratory measurement
The 3 A laboratory high-load test record shows a 94.82% ripple reduction.
Under the same LHY Audio laboratory conditions, with only the power supply changed, the Original T10 PSU measured 61.67 µVrms and LPS-T10 measured 3.192 µVrms.
Tested under controlled conditions in the LHY Audio laboratory. Under the same 3 A high-load condition, only the power-supply assembly was changed. The 94.82% figure is the reduction calculated from this test record; readings can fluctuate and the value is not guaranteed.
Three core modules
Three core modules form the fully linear architecture.
The system combines a main DC regulator board, an AC input and auxiliary linear module, and a custom main transformer designed around the T10 chassis.

Measurement record
Microvolt-level ripple at no load and at the 3 A test load.
Original T10 and LPS-T10 are shown side by side under two laboratory test conditions.
No load
At no load, measured ripple falls from 27.65 µVrms to 2.726 µVrms.
3 A test load
At the 3 A laboratory test load, measured ripple falls from 61.67 µVrms to 3.192 µVrms.
Measured in the LHY Audio laboratory; within each paired comparison at the same load condition, only the power-supply assembly was changed. The 3 A figure denotes the laboratory test-load condition, not an output specification. Readings can fluctuate with measurement setup and unit tolerance; the percentages shown are calculated from the corresponding test records and are not guaranteed values.

Questions, answered
LPS-T10 FAQ
What changes compared with the original T10 power supply?
Compared with the original T10, LPS-T10 optimizes the entire power path stage by stage: AC-input filtering, a fully linear architecture, LT4320-based ideal rectification, 90,000 µF of main-filter capacitance versus the original 28,200 µF, LT3042 + PNP low-noise regulation, wideband output filtering and OCC output wiring. Together, these changes form a complete power-chain upgrade and produced lower recorded ripple under both test conditions shown on this page.
Why use two transformers?
The two transformers give each supply path a dedicated role. The LHY Audio-designed 7N OFC transformer serves the main supply, while a Talema transformer with linear regulation powers the display, control and standby circuits. Each path can therefore be designed around its own load. Making the control-side supply linear also removes the original auxiliary switch-mode stage as a potential source of high-frequency switching noise.
How was the 94.82% ripple reduction in the 3 A high-load test record calculated?
The page records two laboratory test conditions: no load and a 3 A high-load condition. At no load, the Original T10 measured 27.65 µVrms and LPS-T10 measured 2.726 µVrms; at 3 A, the readings were 61.67 µVrms and 3.192 µVrms respectively. The ripple reduction in the 3 A high-load test record is calculated as (61.67 − 3.192) ÷ 61.67 = 94.82%. Readings may fluctuate and are not guaranteed; 3 A denotes the laboratory test-load condition, not an output specification.
Is LPS-T10 plug-and-play?
LPS-T10 is an internal upgrade kit and requires opening the chassis. Follow the installation guide to disconnect the relevant ribbon cables, remove the original power-supply components, and install the new modules at the original mounting points and connectors. Disconnect mains power and allow sufficient capacitor-discharge time before starting; if you are not comfortable working inside audio equipment, use a qualified technician.
Does lower ripple guarantee the same audible result in every system?
Under the same test conditions, lower ripple means less residual AC riding on the DC supply, which can help reduce the opportunity for power-supply noise to couple into downstream circuitry. In some highly resolving systems, this may be perceived as a quieter background and clearer low-level detail. The audible degree will still vary with the complete system, mains quality, setup, room and listener.
