I'm looking to get a rack mountable Pre amp and separate power amp to run 2 Markbass 4x10 cabs (8ohm 800w/ cab). I've scoured the internet and am having trouble finding opinions from people about this kind of set up. I currently have a Markbass Little tube 800. I want more power and headroom. I also like the idea of having everything rack mounted. Thanks for your thoughts.
