Hear! Hear! And the same for the rest of the post as well.
On a related front, in my experience the differences between very good and excellent HX machines is more apparent in the cup than those between very good (Duetto, Vivaldi) and excellent (LM Strada) DBPIDs. That is in no way meant to imply there's not an important difference between the DBPIDs.
Sure there's a great deal of commonality between well-dialed-in DBPIDs above a certain quality threshold, but I suspect that with more time, more cups, and a less distracting environment that many user/drinkers would begin to experience a difference between shots from the different machines.
My (limited) experience with DBs lines up better with Anthony's than Dick's conclusions. The "comparo" is interesting and suggestive, but beyond showing that very good DBPIDs make very good espresso, it's meaning shouldn't be pushed too far.
