In the thread La Spaziale Vivaldi S1 or Expobar Brewtus, I said:

While I don't attribute "sacred cow" status to E61s, there are many who reserve the highest praise for it. For example, the article "The E61 Brew Group. Demystifying the Mystique" on WholeLatteLove says "It's been hailed as the industry standard, revered in coffee circles worldwide, and reverently passed over the lips of every espresso connoisseur in search of the perfect espresso machine - from the newbie to the well-seasoned barista."
What do you think? Is the E61's reputation justified?
(*) La Valentina and Mia have a solenoid in place of the expansion chamber, so aren't E61s as defined by the patent.
