Nice try, but you drop the ball like any other bozo. First of all, pressurized port a filters are for fucking imbeciles, secondly only fucking amateurs use delonghi products and only fool amateurs claim that they can make good cup of coffee using them. Here is minimum system for home barista:

You can't even compare delonghi piece of shit with these products, and the coffe you can make with these. Then you add little drop of this
and you have nice cup of coffee 
I have used a silvia a fair bit, it is a decent machine. It does like a fine grind, though - so it is very important not to skimp on the grinder as some coffees will cause you issues, if not. Cheap burr grinders are the ones you need to beware of as grinding fine comes at a cost.
For those that do not know, the rate of flow out of the head, into the glass is a good gauge of whether your grind is good.
Naturally, some people may be reading stuff like this and shaking their heads, but I'm sure you can all understand that different beans will require different grind settings to get the same consistent pour. I mean, if I grind wood into dust from different trees, the flow rate will be different, won't it? Softer woods vs harder woods etc
My advice to anybody who doesn't understand this stuff and thinks it is lies is stay thinking that.. you'll save money. If you must search the truth, buy a silvia and a grinder and some roasted beans and watch what happens if you leave your coffee grinder on a static setting, without adjusting it for the extraction time. Hint: some coffees will be good, others will be terrible.
