Topping P50

Real hi-fi system bases on an excellent power supply. Topping P50 is such a device, as it offers excellent performance and allows a hi-fi system to perform to its full potential thanks to delivery of clean and sufficient power. While doing so, it is also very practical and versatile, as it is fitted with two USB-A 5V 1A outputs and one DC 5.5/2.1mm jack 15V 1A output, meaning it can be used to supply power to several different devices.

P50 will work and look particularly well with Topping D50s DAC and Topping A50 headphone amplifier as it bears the same visual design and proportions. It is also an excellent partner to Topping DX3 Pro DAC.


P50 can be used to supply power to a wide range of devices with output voltages of either 5V or 15V, and it is an ideal choice to power other Topping products, such as DX3 Pro, D50, D50s, A50, E30, among others.

Each of the Topping P50 outputs, whether it is one of the two USB-A 5V 1A sockets or the DC 5.5/2.1mm 15V 1A jack provides very clean and safe power to even most power hungry hi-fi devices helping them to realize their full potential and deliver a high quality, faithful sound reproduction.

On top of that, P50 has an input voltage switch that allows the user to select either AC 220 -240V 50/60Hz or AC 100 – 120V 50/60Hz, meaning it can be used anywhere in the world.

High quality build

To ensure a very low noise level and low magnetic losses P50 uses a custom sealed toroidal transformer that has been designed to eliminate noise and residual interference to provide the cleanest possible signal.

To further improve the resistance against the interferences and ensure longevity, P50s case is CNC machined from a single block of aluminum.

High energy and low noise

The 15V power supply circuit integrates a series of capacitors of total capacity of not less than 10000µF and the 5V rails have 8000µF, this means a significant energy reserve to ensure stable output signals.

In addition to that P50 uses three TPS7A4700 chips that are the ultra-low noise linear controllers capable of high accuracy, making them an excellent choice for analog circuits.

Per chi vuole il massamo

Lo utilizzo con i topping A50s e D50s, ho provato il dac con varie fonti di alimentazione dall'USB del portatile (da evitare) a vari alimentatori switching per telefoni (con risultati soddisfacenti), ma nulla paragonabile alla pulizia che riesco ad ottenere con questo alimentatore lineare.
A mio parere si arriva a livelli di DAC da 500/600 euro.
Non è essenziale, con un buon alimentatore per telefoni si ottengono risultati più che soddisfacenti (70-80% del potenziale massimo per intenderci), ma per chi vuole ottenere il massimo della pulizia è fondamentale.
