The Métronome DSS 2 streaming bridge…

• In my opinion, from a purely subjective point of view, it brings a (surprisingly) unmistakable improvement in sound and an unexpectedly significant increase in the joy of listening to music.
• Sounds tonally unerringly neutral across the entire frequency range.
• Plays the bass very deep and linear. The entire bass range appears agile, structured, and at the same time, tight and powerful.
• Creates a transparent, open midrange with an impressively fine texture.
• Remains linear even in the treble and achieves outstanding resolution. The versatility of the treble quality is unparalleled – everything from crystalline hard to silky soft is included.
• Is perhaps the fastest and most transient digital source I have heard.
• Plays very nuanced and sensitively in fine dynamics and remains impeccable in gross dynamics while being more inconspicuously realistic than overly extroverted. Both contribute to the high long-term suitability.
• Creates a very deep and high space that extends laterally over the speaker base. It expands the space less toward the listener.
• Creates outstanding localization and precision when staggering, which I have only rarely been able to experience in my chain so far.
• Is very well made, has a practical set-up apart from the lack of a USB output, and does not pose any problems for its users during installation or operation.
