I don't believe in jumping from Silvia/Rocky to HX/Vario as it's not enough of an increment. If I already had a Silvia/Rocky class setup the next step would (and is) a double boiler PID machine and a $1500 grinder to go with.
I disagree. I went from Silvia/Rocky (about 6½ years) and replaced the Silvia with a VBM Domobar Super HX and kept the Rocky, and the difference was apparent immediately. A year or so later the Rocky got replaced with a Mazzer Kony. This also made a big difference. Comparing the Rocky to a Mazzer (any of the better Mazzers, above the Mini) makes the design and precision of the Rocky look pretty silly. They should have kept the old plastic case and spent some time improving the tolerances of the burr carrier system and made it stepless instead of making it look pretty with the metal case.
