Details for bi-amping

I am going for a horizontal bi-amping of my system intending to use two tube monoblocs for the mids and the highs and two SS monoblocks for the lows. The issue is that I have to have the same gain of the Pre-amps driving all the four monos in order to avoid a difference. Some Pre-amps have a pair of outputs allowing them to drive two pairs of monoblocks. Would that be a good solution? Would that be a solution at all giving that the tube monos and the SS monos would most probably have different output power? Would the use of a single Pre-amp with two pairs of monos negatively affect the sound quality? Or I should go for two Pre-amps trying to match theeir gains? I will very much apreciate any hint. Tnx.

I am concerned that unless you have 4 exact amps, and 2 exact stereo preamps, the sound may be difficult to meld inaudibly.
Its not just a matter of gain matching at a particular frequency, but to track all the sound at any frequency exactly right....and too the dynamics have to be the same or the system will sound different at different sound pressures. If you listen to classical music or jazz at all, this would be of great concern.
