I'm still not clear on why there would be a difference in these shots if the groups are showing approximately the same temp before pulling and the machines are both fully flushed.
I have been working on the Izzo Alex Duetto V3 Review
for the last couple months and the ECM Technika IV Review
for the last couple weeks; to the best of my abilities, the two espresso machines were dialed in similarly. The Technika doesn't have Eric's grouphead thermometer installed. I'll install it at some point in the review, but I prefer to start the research section of a review with the equipment as-shipped. As for the taste difference, I speculate that it's due to the hump/declining brew temperature profile (HX) versus flat brew temperature profile (double boiler).

I'm betting on the former.
The video had a cut while we setup for the taste test, so prep steps like dosing and flushing were not shown. Actually, that was the second
take since one of the machines ran out of water mid-shot. D'oh!
