yeah that’s true, the only thing is that i’m not saying that he bought an expensive simple machine. Everyone can buy whatever he want with their money, the only thing is that the problem faced have nothing to do with temperature but with profiling in some conditions and of course you cannot compare the two machines.
In any case back to several years ago we shipped a machine in the US and Homebarista did a test comparing with a Marzocco Strada EP 2 groups (at that age the Vesuvius was the only single group available). So comparing a machine that cost 4 times more than another it’s a bit funny especially because they compared a machine with different group, one it’s an old E61 group with a personalized group. I post the link so if you are curious you can look at the result of the test. Vesuvius Espresso Machine Review (home-barista.com)
