There are two models of Phatlab Chimera, one is pure amplifier and the other one is a DAC/AMP combo.
A groundbreaking innovation-Triode/JFET dual mode amplifier
For the first time, a portable amplifier is equipped with both electron tube and solid-state JFET as major gain devices. Instead of remove and replace process, either device is activated through a simple toggle switch and into action immediately. It is achieved through an innovative circuit topology to embed both devices exactly in the same location of signal path. When switching between JFET and Tube, it is easy to tell the difference between the two. Tube brings a smoother and emotional touch in the music, while JFET is more pronounced and powerful in each note. It is all up to user’s taste and scenario to choose from. And Chimera is named after its dual (tube and JFET) characteristics in one chassis.
Integrated Hi-Res USB DAC
A high performance USB DAC is optional in Chimera for users’ convenience. Although there are plenty of high quality DAP and standalone DAC to choose from, users still expect to use PC or mobile as music source without compromise on quality of digital conversion from time to time. And Chimera D is the choice. ESS9028 is the core of DAC module and USB receiver is selected for Windows compatibility and low power consumption. This combo delivers solid performance electrically with less than 0.004% THD+N and surprising spacious sound.
Quieter, Purer, Greener and yet more Powerful
The improvement of Chimera is far more than functional change. The new architecture and physical implementation delivers a lower noise floor. All the switches are outside signal path to eliminate potential downgrade on signal quality and soft switching scheme is adopted to reduce switching noise. The power efficiency is also improved for 30% less consumption in amplifier alone. The power reservoir is enhanced to same level as Sassy GT for most demanding scenario. And a new output stage is capable of dealing with heaviest load. Yet the phenomenal sound quality is well preserved without compromise.
An amplifier redefines portability for both headphone and earphone Everyone familiar with Phatlab shall easily tell the origin of Chimera from Sassy. Chimera does inherit all the advantages of Sassy II and beyond. By adopting a new architecture, Chimera is capable of delivering 500 mA in each channel with output impedance less than 0.1 ohm and bandwidth beyond 100 kHz. Chimera can serve IEMs with complex drivers and crossover combination all the way up to planar headphones whopping over thousands of mW. Chimera is one of a kind amplifier enabling the mobility of all kinds of phones.
