Dlwask mentioned the need to add some mass to the headshell and suggests it is not the easiest cartridge to setup, which is one concern of mine considering I'll be setting up my first analog setup. From what I've read, the two cartridges seem pretty close. Harry seems to prefer the Blackbird slightly more (and since he carries dynavector, that's seems something to pay attention to) unless I was using a Dynavector phonostage. But some have reported a certain level of brightness with the Blackbird up high.
