Is equal gain OK for bi-amping?

My speakers are bi-ampable. Can I use my W4S ICE amp for the lower portion (28db gain) and then find another amp like a small tube amp with equal gain to run the upper portion? My pre-amp has multiple outs and I want to do this without another volume control between the pre and one of the amps. So my question really is: Will equal gain amps alow me to bi-amp without the need of input volume adjustments? Also is 1 db of difference in gain going to make a big difference?

Before we start on amps, what are the speakers? If it's a 2-way, chances are biamping is a waste of time because the crossover is too high to be of any benefit. Even on a 3-way, anything over 300 Hz, is getting uncomfortably into the sensitive midrange. Personally, I wouldn't biamp over 150 Hz unless going active.

There are Endler EVS/Rothwell inline attenuators but they aren't designed for fine tuning as much as coarse volume control and the input impedance can be low for an already divided setup.
