An update.
First, the cups. They replaced the one that failed with two, I think that's a result.
Anyway, coffee. Yeah.
It was interesting bringing the new gear into play, as I was able to use the same beans and expected to be able to compare. I'm able to produce a half decent shot now, with reasonable consistency; I can report, honestly and without hyperbole, there is no comparison, it just is not the same drink. The flavours in the proper espresso are different and, yes, better. The best output of the old gear comes nowhere near the same drink. That's not to say it wasn't a pleasant drink, it was. But, this is better. I suspect, if I CBA, that using the new grinder on the old machine would have improved matters, but that's bye the bye.
As it happens, it's not always in a good way. The "French Breakfast" blend which I enjoy as filter or cafetiere and also through the old espresso machine doesn't taste good to me as espresso through the new gear. That's fair enough, I would describe French Breakfast coffee as intrinsically filter.
