exactly like my BIII, so I'm looking forward to hear your solution. I got the crema after about 11s, this is where it reaches about 8bar and to it's peak (9bar) pressure at about 12s. So for about 11s it's all just coffee drip :( My silvia produces more crema with La Marzocco original single basket. With the same basket, coffee ground & weight I got much less crema with my BIII. Even my 100 bucks magimix Nespresso machine produces lot more crema with a hacked capsule filled with merely 6gr of the same MXK grind toraja coffee bean. I'm thinking it's the problem with the pump, the pressure relief, or bend hose in the inside or something, but I'll be watching if someone has the answere to this for now. -- Regards, Liys
