Yes, when it comes to capacitors, bigger is better. I have some in my portable rig that dwarf EFN's -- they are 150,000 uF and the size of soda cans. They are a bit awkward to tote around but they sound AWESOME. I am trying to hunt down some even bigger ones. I have a line on some that were used in the Soviet space program in the 60s. They are 750,000 uF and each one is the size of a fire hydrant. They should sound AMAZING.
