Query: good machine, but a bit weak taste

This is a great machine, very easy to use and easy to clean. However I feel the espresso it makes is a bit weak compared with other "non-automatic" machines. Perhaps it's because of the coffee granularity it can accept is on the coarse side, or because of the water-pumping-up as opposed to the classic design. But overall, it's well worth the price.
