IMS La Pavoni Precision Portafilter Double Basket (Millennium)

Precision is right, though I don't have the palate to taste the difference, I can see the uniformity in my shots as well as in the manufacture over cheaper alternatives.

I like these pucks more than the factory one. Enough said

This basket provides rounder, more uniform holes and less burrs than the stock basket -- in my case, especially around the edges. It is very slightly (0.2mm) shorter. Because the basket resistance will likely be less, you will probably have to grind a little finer. I found that, with careful grinds distribution, the effect was visible with a bottomless portafilter. It is a little pricy, though and only fits La Pavoni models made after 2000.

I replaced the pressurized filter with this one. It is a bit tight but it works. I have not seen any difference.
