Well, it's not easy to find the correct tools...
I didn't really have time to read all posts thorougly when I brought up Le Bass as an idea.
It's very versatile as a preamp and to my ears it's even nicer than other offerings from DarkGlass or Tech21, but it's certainly not a "press a button and everything is solved" kit.
Also, the DI out on it has some noise (about +10dB compared to it's line out).
I started building my gear with a Digitech BP-355, which has stereo XLR outputs as well, I even gigged with it using just the pedal, some Behringer bass amp the venue had as monitor and going through FOH and it was ok. However I am not a big fan of it's amp models, eq and compressors. Also used it for a gig with a rented PA system, where it sounded much better as I was able to eq out some of it's boomyness (if this is how you say it correctly). Of course it's all about personal preference...
Actually building a pedalboard around a good preamp might just be the way. I don't find changing eq settings a real big issue with an active bass (although the 3 position preset mid pot really helps on my Yamaha BBN5A). If you're not afraid of tweaking a zillion of parameters with a computer, the TC SpectraComp is a great and cheap solution for compression. Also DI out problems can be solved quickly with a quality DI box, that way you don't have to worry if your preamp/multieffects unit doesn't have a decent DI out.
I hope you can find some usable ideas in my post, Friday is usually not a good day for my brain.
