Know before you buy
Current Mode Amplification processes audio signals in the current domain rather than the voltage domain. This approach significantly reduces transient intermodulation distortion, resulting in a faster, more transparent, and highly detailed sound profile.
Yes, the CMA Fifteen features analog inputs that allow it to function as a high-quality preamp. You can connect your turntable to the RCA inputs and use the device to control volume and drive your power amplifier or active speakers.
Yes, the CMA Fifteen provides full MQA decoding. This means it handles the entire unfolding process internally, ensuring you hear the studio-master quality audio exactly as intended by the artist.
For the best performance, use the balanced 4.4mm or XLR outputs if your headphones support them. These outputs take full advantage of the device's fully balanced internal architecture, providing better channel separation and power delivery.
The CMA Fifteen supports the LDAC codec, which is currently the highest-resolution Bluetooth standard available. While wired connections remain the gold standard for absolute fidelity, LDAC provides a significant step up in clarity and detail compared to standard Bluetooth codecs.
The CMA Fifteen is built with a 10mm-thick aircraft-grade aluminum chassis, which acts as a massive heatsink to manage internal temperatures. It is designed for desktop use, so ensure you place it on a stable surface with enough clearance for airflow to maintain optimal performance.
