Phatlabs Phantasy

Class-A Single-Ended Triode Portable Headphone Amplifier

PHAntasy is the first member of our Portable Headphone Amplifier (PHA) series. When we kicked off the development of PHAntasy, we determined to achieve two major goals; One is to preserve the true spirit and performance of SET amplifier, pure class-A, transformer coupled output and most important of all, sensational music presentation as we ever experienced on best SET amplifier, and the other is true portability with rechargeable battery via 5V USB port. We examined every detail of SET topology and audition every possible valve candidate and come up with JAN6286, a military grade directly heated triode (DHT). We examined the topology and each element of the amplifier – JAN6286 tubes, boost converter, filament supply, Battery configuration, and Passive Components - to find the best sounding components and combination. As we put them all together we ended up with The PHAntasy, a true fantasy to audiophiles.

Headphone Amplifier Specifications

Digital-to-Analog Converter (DAC)
A Digital-to-Analog converter (also known as a DAC) converts a digital audio signal into an analog signal. This is especially helpful for listen to music from digital sources, such as iPods and smart phones.
Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
10 - 60k Hz
Output Connection
This is the manner in which the headphone amplifier will output the audio signal.
1/4" Plug
Number of Outputs
Some headphone amplifiers have a built-in splitter so multiple pairs of headphones can be connected to it. The number specified here is the number of headphones that can be connected to the amplifier.
Output Power
This is the output wattage of the headphone amplifier. It is measured in mW.
250 mW
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
