Topping A50

Balanced Heaphone Amplifier Silver

Topping A50 Amplificateur Casque Symétrique Argent

The Topping A50 is an efficient and affordable sedentary headphone amplifier. Its careful design makes it an ideal ally for any audiophile wishing to enjoy a rich and clear headphone listening experience. The amplifier is Hi-Res certified, a label that guarantees a very good sound quality.

Balanced / Single-ended connectivity

For its connectivity, the A50 is both simple and very efficient. It integrates a single stereo RCA input but has 3 headphone outputs, one of which is balanced on a 2.5mm jack connector. A stereo RCA line output is also available on the back of the unit.

Aluminium case

The components of the A50 Topping are hidden under a beautiful and robust CNC machined Aluminium housing. It is also designed to effectively dissipate the heat released by the power supply and PDOs.

Digital volume

The A50 scans the position of the volume knob and transmits the data to the JRC1195 controller for a precise adjustment of the volume level. This chip also provides a perfect volume balance between the left and right channels.

AOP

The amplifier includes a pair of LME49720 PDOs mounted on a DIP8 bracket. It is therefore possible to easily replace these PDOs to adapt the sound reproduction to your listening experience.

Regulated power supply

The power supply circuit of the A50 is stabilized by low noise TI TPS7A33/47 linear regulators. These high-performance chips provide clean and stable power to all A50 circuits.

A50 Headphone amplifier + P50 Power supply + D50s DAC Association

The Topping A50 completes the range also composed of the P50 and D50s. The combination of these products is ideal and allows you to benefit from a complete and efficient system. The D50s DAC allows efficient digital-to-analog conversion, supports high-resolution files and allows Bluetooth transmission. The ultra-low noise regulated linear power supply P50 will provide the A50 and D50s with an extremely clean power supply, allowing them to reach their full potential.

I also like that Amp..
.. but I'm only a listener, it is my second Headphone-Amp. For me it sounds nice and can drive a Sennheiser HD650 at +9dB loud enough for my ears.
I can't say anything more than the reviewer before, it's all I perceive myself.

The ordering process from Germany was very agreeable. I had one RMA, but it was a problem with the source I connected, not the Amp itself. The RMA was really painless. The concerns ordering a product outside my country are discarded. Thanks for that nice and gentle process!

Versatile headphone amp
I am using this connected to the Topping D50s DAC. It drives my AKG K712 and Sennheiser HD headphones. It can drive them both at the same time which I especially like because now both my wife and I can listen to the music at the same time :-) or I can switch the headphones for different genres. And it sounds fair enough good. Clean, no hissing or buzzing, not warm sounding, not cold sounding, the bass is good, feels like it has a tons of power, around 10-11 O'clock on high gain sounds like you are at some live concert. I also like the way it controls it's line out so when you turn it on it disconnects the line out (to my amp+speakers). The relays operate quietly and quickly. The volume knob is smooth. The device feels robust and really nice built. Tried also some other opamps but eventually returned to the original LM49720. So here is a first con: there is simply no place for some custom built opamps on adapters, only for regular size DIP8 chips. Keep this in mind if you want to give a go to some opamp rolling. The only real big thing I could image that would make this device just perfect would probably be a remote control as the volume is already digitized. But, well, for the price, it already has many qualities and features. And perhaps the biggest and serious con is a power button that serves as a power button on long press and as a gain switch on short press. So the one has to be extra careful when operate this button and listening at low gain because a short click will switch the output power to high gain.
