Phatlab Sassy

Single-Ended Triode/Solid State Hybrid Portable Headphone Amplifier

Sassy is designed for every enthusiast and audiophile who enjoy sound of SET amp while demands more portability and practicality. Sassy as 2nd member of portable headphone amplifier (PHA) series has inherits many technologies and advantages developed for PHAntasy, the bigger sibling. One may immediately notice Sassy’s extremely compact and light-weighted ever seen for a tube amplifier. The secret is elimination of output transformer and choice of high efficiency subminiature tube. A newly developed full-discrete solid-state output stage replaces costly output transformers, which is capable of delivering precise and powerful energy into headphones no matter what impedance and sensitivity.

The biggest difference sets Sassy apart from traditional SET amp is solid-state output stage. The effort is beyond imagination and takes much longer time to come up a viable solution with satisfactory performance. The challenge is to make it stable and consume extremely low power, while faithfully delivering SET signature of sound and plenty of energy on demand. The efforts have finally paid off. Sassy is capable of up to 20V and 1A output that is something never been done in such a small form factor. Sassy meets the balance of both worlds with sweetness of Single-Ended Triode and precise slam of power transistor. Sassy’s overall tonal balance and driving capability are comparable to best amplifiers either desktop or portable formats.

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 - 100k 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.
180 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.
Amplifier Style
Some headphone amplifiers are designed to be portable and others are meant to be placed on a desk. This will tell you what style of amplifier this item is.
