Good questions….
Quieter? About the same, maybe a little faster.
Heavier? Not sure what that one means.
More clarity? Yes! I it’s a less muddled brew. Certainly with the medium roast beans I’ve been using.
Better in the cup because….. Taste!
There is more retention, now, by about 0.1g, but I’m okay with that considering the improvement in taste. I tried the SSP HU a few weeks ago, and preferred the stock Mazzers, but that might be because the grinder was new. These DLC burrs seem to work well with the Duo.
