Um, the link is to a post of three of us pulling shots of the DC versus the Elektra, and not being able to pick out which is which.
There's an odd observer effect here. The machines were set up to pull optically indistinguishable shots using settings at which each performed fairly well. A test where you flat out try to pull the best shot from each machine using the same coffee and grinder, would probably result in different looking shots, which would make blind tests hard.
Blind tests almost always fail to reproduce the reputed differences between two foods, beverages, hi-fi systems, assorted equipment, etc. This is so frequent that many taste mavens, audiophiles, etc, are giving up on them. However, I would hate to assert a difference in the teeth of a blind test that was well conducted. Especially when it was me who couldn't tell the difference!
