58's and 57's have NOTHING in common except the brand name. They sound totally different, and you'll need to listen to the difference. The 57 seems to works better for girls voices ( at lest, the girls I know) and they both have significantly LOWER outout gain than the EV I use.
I also have several AKG C1000s's and I love them in the studio. They are very sensitive and have great output, but require a battery or phantom power. (which the PA80 does NOT have)
The day of the SM58 is not over, but it sure has a boatload of competition in the newer models. Even the Shure Beta versions are an improvement. More sizzle, more punch, more volume.(more $$$ too)
Go listen .... don't shop for a mic on line.
