The results with several devices in the price range of a few hundred euros proved that their internal clocking was the main weak point in the sound of cheaper older converters. This is how the current audio interface Clarett by Focusrite quite literally blossomed. The success of Mutec clocking on my two Lavry converters was also clear though somewhat less far-reaching. This also reiterated how Nano eclipsed the MC3+ USB. In particular the bass range which sometimes minimally floats on the DA11 felt a lot firmer with Nano clocking it.
Even as a pure clock the Mutec system made a clear difference but things got particularly interesting when the MC3+ played USB interface and also supplied audio signal. During the test I was able to see directly how the performance of the already good clock of the MC3+ USB was significantly improved by the additional connection to Nano. In the consumer hifi sector, clocking is seen as one of the last optimizations for the playback chain. In the pro sector however, it is a technical necessity due to the number of digital devices that must be sync'd to a shared clock.
In fact, external clocking in the home can achieve much more than a final touch. The improvements can be downright substantial. I would like to say that a good stable clock can do more than any cable. That's why I recommend trying external clocks in your own system. Even where they only control streamers or other digital transports without D/A conversion, something can really happen. The sonic gains are usually noticeable, sometimes even overwhelming.
In any case, Mutec's REF10 Nano showed a clear dimensional improvement in the soundstage and in most cases there were also significantly tighter highs and often crisper bass. With this clock, Mutec produce a reference device made in Germany then charge anything but a ludicrous price for it. If one of your digital devices has no 10MHz input, I recommend the combination with the Mutec MC3+ USB. I actually like to avoid the term but it probably fits here: these Mutec clocks are secret weapons on the path to audio system optimization and the perfect sound.
