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, new designs, which leads to further sound improvements. The upgrade also helps prevent possible errors/repairs caused by outdated electrolytic capacitors (s30s have been built since 2003).
