THX is engaged not only in certification of equipment for commercial and home theaters – its portfolio also includes Achromatic Audio Amplifier headphone amplifier chips (for example, we managed to test a FiiO player with such a chip). And it is on the basis of the THX AAA-888 chip that the Mytek Liberty THX AAA HPA analog headphone amplifier works .
According to the company, the new product is a reference-level device for any passionate headphone aficionado and audio engineer. The sound, if you believe the description, turns out exactly as the creators intended it. The amplifier provides maximum transparency and detail with minimal distortion from the device itself. This was achieved through the use of proprietary THX topology with forward error correction. As a result, the amplifier operates at maximum power with exponentially reduced levels of distortion and noise.
This system allows THX AAA amplifiers to work with any headphone, even the tightest and most sensitive – it delivers a maximum of 6 watts of power with less than 0.1 dB harmonic distortion. There is also a choice of gain – four different levels are available.
With such a lot of power, I had to take extra care of protecting the circuit. A huge 60 W linear toroidal transformer with automatic switching to a suitable voltage in the network and regulators in the double mono format is responsible for high-quality power supply.
Of the connectors, this version of the Liberty has four line inputs: three RCA and one balanced XLR 1/4 inch. Outputs include 4-pin XLR, 4.4mm balanced, 1/4-inch TRS and 3.5mm in-ear monitors (when connected, the gain automatically drops by 12dB). There is also an RCA pre-out – in this mode the Liberty THX AAA HPA can also be used. Switch “Crossfeed / Mono” will allow you to adjust the device to other elements of the audio system. A large 27mm Alps attenuator is responsible for volume control.
The cost of the Mytek Liberty THX AAA HPA in the US is $ 1,495.
