To be honest, it's my first Synchro so I can't really compare, but I know there are slight improvements going on all the time - Craig has a very strong relationship with the designer and builder. I do know there will be a new mod coming in soon, but I can't disclose that one unfortunately. This one has flow restrictors installed and the 9bar guys have calibrated the temp to suit one of my custom blends so well it's insane. Alas, I have but 7 days to play.........the machine will be in the back of my van next Friday and making it's way to Mildura's best cafe - Cafe94, where they pump out 3500+ perfect coffees each week - so it will be getting a good workout. If I had some suggestions, it's make the High-Group a bit higher so that 16oz cups fit neatly under the PF and perhaps a slightly longer steam wand, but that's an easy fix. The shot timer on each group is pretty funky.....
