The nurri takes below or at 15 minutes to fully warm up. The group head temp Is totally stable as the pid directly regulates it constantly through an independent heater that only heats up the grouphead. If I want to change temperature, it only takes a few minutes. I havent used a LM machine so I'm not familiar with how temp stable they are.

I'd wait until Paolo reveals his secrets then decide. Should be interesting!

Is someone named Paolo coming out with a review of one of those machines?

Paolo - acs designer of the Evo, Vostok and many more.

Oh he meant the owner of acs!

The way I see it ACS and Nurri are relatively small companies that are rapidly innovating and evolving their designs. There are enough differences that individual people will have preferences but they are much more similar than different. It's like differentiating between E61 DBs.

In a couple of years they will likely have settled down to a more stable feature set.

I would classify the levers from both companies as belonging to a category I would call hybrid levers where they have pumps for variable preinfusion combined with pid controlled components. I don't think that general categorisation will change. However they embody quite different approaches to provide solutions to the same problems so to speak and so they should appeal more to differnrt groups of people.

Agreed. The ongoing fighting and debating between the same couple people about these two machines seems kind of silly to me. They're basically the same machine.

No, that statement is absolutely not correct....they share a group, but that's it. Antonio used a different group initially, but moved to using the same group as ACS some time ago.

I guess we have different interpretations of what it means for two machines to be similar. When looking at spring levers in general these two seem to share a lot more in common than just having the same group. Dual spring pressure profile, fast heat up time, precise temp control, precise PI pressure control, brew pressure gauge. I get they each have some differentiating features but as far as I'm concerned they are more similar than different, and more to the point, this ongoing "my machine is better" debate between these two users over several threads is getting old.
