My thoughts are that there's no free lunch. Everything has a sonic signature. The Pete's place had the most unbelievable plosive protection. I will be using this on my Leslie for sure, where the wind is a definite problem. I might even be able to not have to mic outside the louvers. It definitely has a sound, though. They all do. Maybe the Popper Stopper or the Pauly were the most transparent, but their plosive protection was the least efficacious. The Steadman does a good job with the plosives, but has a sound to it, as well. The foam I liked the least, and it's because it changed the environment of the capsule. I felt like it's sitting in a different housing now, as the space around the capsule has a different sound to it. It had less to do with the fact that I was losing the most highs, and more to do with the difference in overall sound.
I've personally been using the Steadman for a while, but I am really going to change that for now. On certain mics, I'm going to see if I can get away with not using any filter. Some mics , I will have to, just to protect the capsule. But for now, my days of defaulting to using a filter might be over.
