I ever had a Lambro with a new spring which was 8 bar.

65 years old probably.

It's definitely not too weak - I think this is just a personal preference thing. I've never had an issue with the standard spring and love the shots this machine produces. I replaced a Profitec 800 with this machine and don't miss the 9 + bar spring at all.

I agree that its personal preference but my machine didn't even have 6 bars, it showed just under 5 bars when measuring. Shots were just week except for some very dark roasts. After installing 6 bar spring shots improved much better. Now i have 7,5 bar pressure which for me is optimal.

I'm happy that each of you have an opportunity to have the Cremini SL that is providing exactly what is expected in each individual case.
pcdawson: I agree that the SL is providing the perfect extraction you want... and that's terrific.
This also depends on the variety of beans used and their roast level.

But for others, If the extraction is left wanting, besides the 'Art' of the espresso pull...there is only two options: water temperature and water pressure.
I think it's exceptional to have the opportunity if wanted to have an alternative that LuanD has offered.

And it gives me comfort if I were to purchase the SL .... there is an acceptable option that I can install to manipulate the water pressure. Otherwise I would only have one option, the one offered by Olympia.
