The Technika (edit: but not the VI) is an e61 heat exchanger machine. The synchronika is a dual boiler, e61, top of the range. The Profitec Drive is a less refined synchronika, but with the exact same internals, and it’s the top of the range model for Profitec - but for all intents and purposes they are very much the same.
There’s a massive difference between Heat Exchanger machines and Dual Boiler machines in how they work. I’d recommend you do your research, it’s well documented here and elsewhere… and then take a look at the ECM Mechania Max. 😊
Edit: ignore me. Looks like I haven’t done my homework. The Technika VI is actually a dual boiler, unlike the other machines in that range!
Edit 2: the Technika VI seems to be a compact version of the Syncrhonika with smaller boilers.
Edit 3: looks like one of the key features is simultaneous boiler heating - something the synchronika and Drive (when it was Pro 700) used to have in the past. I can’t find the specs, but maybe they reduced the power of the heating elements hence the smaller boilers?
Also it doesn’t seem to have electric heated group like the synchronika II.
