The Amethyst preamplifier is Trinnov’s flagship high-end stereo product. On a single chassis, it combines an audiophile preamp, active crossovers, high-quality 24 bit/192kHz DACs, a network renderer, and the world’s most advanced speaker/room correction: the Trinnov Optimizer.

The Amethyst includes an 12 input preamplifier with built-in Speaker/Room Optimizer, Trinnov’s innovative HybriD Phono Preamp, a Network Renderer, a 24 bit/192kHz DA Converter and a 2-way intelligent, active crossover engine. It also features built-in Wi-Fi connectivity for simplified operations making it the perfect centerpiece of any traditional or modern HIFI Installation.

Highly accurate, transparent and revealing as a pure preamp, the Amethyst elevates stereo playback through its state-of-the-art room correction system that reveals the best of your loudspeakers with incredible focus and imaging stability. High-resolution audio sources, up to 192kHz, are processed at their native sampling rates, never converted or down sampled.

With 64-bit floating-point processing, true signal integrity is assured, producing resolution greater than 320dB and enabling digital volume control without any loss of resolution. As the heart of your system, the Amethyst accommodates a total of twelve digital and analog sources, even including an analog phono stage for LP playback.

Straightforward Automated Process

Setup is guided by the Optimizer’s calibration wizard, which enables system optimization in a matter of minutes.

The wizard creates five presets with different acoustic flavors to get you started. Further fine-tuning is available through a deep set of additional tools, with up to 29 individual presets available for saving custom settings.

Why Room Correction Matters

The Amethyst delivers an outstanding transparent sound and provides a versatile set of features as well as rich connectivity.

However, it stands out with its built-in state-of-the-art room correction system to ensure true-to-source sound reproduction in your listening environment.


Any tablet, smartphone or laptop can control the Amethyst over a local network. Connection is available through Ethernet or Wi-Fi. The Amethyst can also act as its own Wi-Fi access point and is a network UPnP/DLNA player. An IR remote is also provided for more conventional operation.

More than 2 Channels

The Amethyst provides four output channels for stereo playback, enabling active crossovers, intelligently calibrated, for bi amplified speakers, or bass management to drive one or two subwoofers.

The stereo channel configurations available are 2.0 with no subwoofer, 2.0 with bi amplified speakers, 2.1 with a single subwoofer or 2.2 with dual mono or stereo subwoofers.

Roon Ready

Roon has become an industry standard for streaming high-resolution music to high-performance stereo and immersive audio systems.

The Amethyst, like all Altitude preamp/processors, is a Roon Ready network player, enabling you to enjoy your music through its direct Roon interface. Roon network playback utilizes the Amethyst’s exceptional internal clock, ensuring the highest possible audio quality.

What Do Others Say?

    Trinnov’s Amethyst DAC-preamplifier-processor is one of those rare components that reveal immediate benefits on first hearing. After running the preamp’s Optimizer calibration, I noted a dramatic cleaning-up of bass definition and a related tightening of midrange focus. Soundstage depth improved, and I experienced clarity and precision from even the most densely mixed of my reference tracks.

    In the end, I loved the Trinnov Amethyst so much that I kept it. Yes, it is fairly expensive, but to me, it was well worth it. For me, it’s also a huge advantage that its flexibility and power allows me to re-calibrate it myself to suit any room or system change. But all that wouldn’t matter one tiny bit if it didn’t sound good. But it most definitely sounds superb. Give it a listen, you may well feel the same.

    Without the acoustic correction system engaged, the Amethyst already behaves as an excellent preamplifier/converter that does not demerit at all at the price offered. By engaging the acoustic correction system, we discover a whole new world that we had not yet imagined.

    It is the concentrated «savoir-faire» hidden in the Trinnov case that is very impressive. To my knowledge, the Optimizer is the most Subtle correction processor that can tell the difference between useful fixes and those that might add problems. If I had to emphasize a single benefit of Amethyst, I would insist on its particular ease of use!

    The big hit, apart from the unparalleled Flexibility in signal and memory management, is the Room Correction Optimizer, which lives up to its name. Thanks to three-dimensional acoustics measurement and flawless corrections for timely reproduction, the overall system always sounds fantastic, natural and somehow “right“.
