Well...the list you've provided is certainly quite nice. I'd imagine you could do well by purchasing any of them.

I've only had experience with the Vintech, API and Focusrite. The Focusrite wasn't my cup of tea. It was nice, but it just was nice. Nothing special. The API has character - a bit of soul. If you want something to impart a little punch or forward drive, this is it. It's not overwhelming, but it's perfect in oh so many mixes.

The Vintech is a bit juicier still.

What are your plans for this preamp? Vox, drums, guitar, choir, etc???

I would urge you to consider the Langevins as well. These are serious pres that are often overlooked and because of that, very well priced.

Well I have the ISA 428 and a Digi003, mainly would use the new pre for Drums but I would like to be versatile.

for drums I'd lean to the API3124
it's a cool, familiar rock /pop drum sound and you get 4 of 'em
:roll:
??
now you're gonna tell me you record jazz
mmmmmm but that's ok
cos they still sound cool
