常見問題常見問題

超低雜訊與純淨供電：

核心晶片:

Utilizes Linear Technology's next-generation LDO chip, the LT3041, in an innovative 5-parallel output configuration. This design effectively lowers output impedance, achieving high bandwidth, low internal resistance, and ultra-low ripple characteristics, providing the DAC with a clean, high-transient-response power source.

實測效能：

The unit's no-load ripple is below 20μV, and remains under 100μV even under high-current output, ensuring superior power purity.

高效率與低發熱:

A very low dropout voltage design significantly improves overall efficiency compared to the previous generation, reducing heat generation by over 60% for stable long-term operation.

高階元件與精密製作:

電路板製程:

Features a 4-layer PCB with gold immersion plating, ensuring superior electrical performance and signal integrity.

主要元件:

Employs high-current, low-internal-resistance Schottky rectifiers, Philips Vishay BC 058 series large-capacity electrolytic capacitors, X7R MLCC capacitors, high-precision low-temperature-drift resistors, and Panasonic electrolytic capacitors to ensure stability and dynamic performance.

散熱:

A pure aluminum heat conduction plate is attached to the bottom of the PCB for enhanced and lasting cooling stability.

完整安全保護:

Integrated protection against short circuits, overload, and overheating for complete safety of connected equipment.

隨附高品質線材:

Bundled with an Ultimate Series high-end DC cable. The cable uses high-purity oxygen-free copper conductors with precision processing; the DC plug is a 24K gold-plated aviation connector for a tight, low-impedance connection, ensuring minimal signal loss.

問：LPS-50 與 LPS-50 Pro 有何不同？

A: The LPS-50 Pro is an upgraded version of the LPS-50, featuring higher-grade internal components and an improved circuit design for better overall performance. It also comes standard with our Ultimate Series output cable, specially designed for high-end audio equipment.

I had purchased the LHY as-8pro previously and it cleaned up my streaming considerably. I never imagined the tonal improvement from top to bottom as well as timing/immideacy a power supply on my router would have in my system. I think the picture on the TV is more crisp and it starts faster. Honestly, I could not be happier nor did I suspect such a large change.
The people at LHY audio are top shelf as well.
Very impressed!

Perfekt Quality and Perfect Sound !

I bought the power supply for something else, but first tested the power supply on my RIVO+ instead of the LINEO 5 power supply from Volumio.
WOW!!! It sounds so much better, natural sheer unbelievable! I am over the moon. So I have to order another one...

I've only had this unit a few days so not sure if my evaluation would be premature. In my 2-channel setup, I have a 3-Tier Diretta/Audiolinux architecture being used as a high-end transport. So there is a GMTEK NUC (Roon Core), RPi 4 (Host), and RPi 5 Target. I purchased the LPS to power theTarget so it was great that LHY offered to build a custom cable p DC power cable to accommodate the RPi. I also paired the LPS with an Audioquest NRG-Z3 power cord. So both the LPS and NRG-Z3 is in the "burn-in" stage, I was able to clearly hear an improvement from the standard SMPS supplied with the RPi 5. Over the next 100hrs or so, I'm expecting things to settle in but I am already impressed with the opening up of the soundstage, out of the box. I had a lot of questions before making the purchase, and it was all handled very well via "chat" with LHY. After ordering, the unit arrived surprisingly quick (5 days), in a very well packed double-box. It's early but if I had to complain about anything (and it's really more cosmetic than a complaint), I wish the LPS had the ability to turn off the display that shows the voltage. It's very bright but easily suppressed with any type of covering (i.e. tape, etc.).

Amazing customer care and amazingly fast shipping. The psu in and of itself is noting short of fabulous. I would not hesitate to recommend LHY to anyone in need of an audiograde psu.
