I can only laugh at the time/money some spend in their pursuit of the hyped next best thing. Once a decent level of equipment is reached you’re just pissing in the wind trying to get much more than .5% perceived improvement. By far the most important variable is the coffee being used. I have a very capable machine/grinder setup that gives me exactly what I prefer with straight espresso, main focus is on green selection/roast development. That will deliver by far more results in the demitasse than all equipment changes made regardless of price spent.
Also don’t buy into the ‘supertaster’ bull**** as we all have different levels of taste/aroma perception. None is better than the rest, just different. Hilarious when some mention they aren’t on a ‘professional/expert’ level when discussing their findings on coffee, equipment, etc. Only difference between professional and amateur status is the pro gets paid to do it, definitely means nothing in the way of actual skill/knowledge on a given subject.
