Two questions, is there a sonic difference between doing the voltage divider verses negative feedback on the extra gainstage in the bass channel?

I hate the new jensens.
I own a bunch of them and have ended up swapping em all out for other stuff.
I prefer WGS and Eminence.

Re: gain stage question

I am a fan, after much experimentation,
