The DNM descendant cantata C50 has an improved power supply in version 2.0 and now has even higher quality 4-terminal/T-network capacitors. The result is a more impressive sound and higher detail resolution with legendary musicality and gripping flow. With this upgrade, the Opus 21 s30 amplifier can now also benefit from this impressive sound improvement. At the same time, all electrolytic capacitors are replaced with high-quality, state-of-the-art ones, which leads to further sound improvements. In addition, the upgrade also helps to prevent possible errors/repairs caused by outdated capacitors (s30 have been built since 2003).
