I've not used my SM57/58s in years. I only keep them around for the "we all use our 58s. Please bring one so that you match." gigs that I used to have before 2020.

They were state of the art 60 years ago but time has passed them by. The basic design is good but the output impedance should have changed in the 1970s when inexpensive FET PAs came into being. Have you ever read this? SM57 Impedance

The Gizmo mentioned is easy to make and I'll put a new batch on Reverb now and then that sell out quickly. I prefer using a 1kW variable resistor in a box that allows me to tune the low end and alter the transient response—think of it as a Cloudlifter CL-Z without the boost.

That Shure KSM8 you linked to does look nice. I've been using AKG dynamics since 2008. The Varimotion diaphragms and 600Ω output made a noticeable improvement in my live sound—and all my bandmates noticed. Only downside is that one can tell when a vocalist is mumbling because he/she forgot the words.
