- Quality of the espresso produced - how do they compare.
Consistency and ease of use - It takes a couple of flushes and a sink shot for me to prep the Olympia to pull those transcendental shots. It's a lot of effort to get to 1 oz. of really good coffee. Will the CT1 get there faster? By the time the Olympia is in "the zone" I have water for maybe 4 shots. So not a house party machine.
Possibility of pressure profiling - I have been looking at the Naked Pressure profiler for the Olympia Cremina 67. If this opens up new possibilities in control and consistency this might tip the scales in favor of sticking with the Cremina. Any experience on the impact of this mod on life with the Olympia?
