Donnie...Did you ever establish what impedance setting you liked best on the ISA? For my ears, I stay on the 110 setting for everything. I've had my 428 for several years now and it seems best as a general rule thingy......

I won't answer for Donny, of course.
In my case, I always start with 110 and experiment when I feel like it. I found that higher settings work good for drums to get thighter sounds,
It's all what work at a specific time to me. It makes more difference on a dynamic or ribbon mic, tho..

Hi Dave :)

It really depends on the mic I'm using at the time, and the sound I think works best for a particular track.
I have a pair of vintage 414 EB's, for vocals, both seem to sound best at the "medium" setting (I think it's 2.2k?)
But I've tried a newer 414 that sounds best at the 110 setting ...though with all three of those I used, the differences were pretty subtle, small details that probably only an engineer/audiophile could discern.
A few days ago I mic'd up my acoustic with an AT SDC, and ended up using the lowest setting...maybe because the mic was already inherently "bright" to begin with? I'm just guessing on that, the low setting had a nicer low end -for that mic- on a strumming acoustic track.
The MOST noticeable difference I heard, was with a Ribbon mic, and the differences were quite obvious. The higher impedence settings made the mic brighter, increased the gain, but seemed to take away some of the warmth in the low mids that ribbons are inherently known for.
My default when checking the various settings is to start at the 110 setting. This setting sounds great with dynamics such as 57/58 and the EV RE20.
I've not been "unhappy" with any of the settings on any of the mics I've used thus far. It's pretty subjective, and, for me, also greatly dependant on the context of what I'm working on at the time. :)
