I dunno. If you look at my upgrade path, I went from getting good shots on Silvia with the occasional great shot to a pro two-group with a 12 litre boiler and a 4000W 220V element. I still pull sinkshots with it, though. PEBPAG (Problem Exists Between Porta-filter And Grinder)
My point was that the better machine makes pulling a shot more consistent and easier, while a better grinder makes better espresso.
Hey, I could be wrong...
I agree about consistency. As HB pointed out on another thread internal configurations of machines vary and affect extraction even between similar e61 HX machines. The difference could be noticable in the cup and require an operator to change some routines from one machine to the next.
I used to get really clear, well defined shots with a Silvia once in a blue moon. Now that I've changed dose/distribution tamp with my e61 HX upgrade I'm getting consitently deep charactered shots. The e61 HX is almost 3 times the price of the Silvia but it's starting to give me more than 3x the consistency. Not to mention the adjustability and steaming convenience. Personally I think a good machine is worth every penny. A good grinder even more so.
I also upgraded from a Rocky to a Macap M4 stepless and the grind is much easier to control. If you're starting out and trying to define espresso as far as how to make it and what good espresso tastes like using pre ground coffee might be disappointing and frustrating. From what I've read it takes very little air to oxidize roasted coffee and grinding it exposes even more surface area. Instead of days oxidization occurs much more quickly, minutes if you're really concerned with the kind of freshness that produces good crema and taste.
