I haven't done the hydraulic press thing (I didn't look for a tool). I do know these FP-203 spades are impossible to crimp with normal tools. I have always used the FP-201 spades instead. They have screw-down clamps to hold the speaker wire, and you can still apply solder through a hole at the top. Just make sure you use a larger 2mm tip and crank the heat up to max (like 450 degree C). Be patient because it takes a little bit for the spade to heat up (it's a giant heat sink).
