Hey guys, I currently own a BB434 and a BB714 BS and love both, but I would like to hear your for feedback on purchasing a 1024x versus a 734A. I found a used 1024X for similar price of a new 734A, and the 734A is basically the same as the 434 except the preamp and a few tweaks, so thinking that a 1024x would make more sense. What I wanted in fact was to buy a used BBP34 (because the new is too expensive) but they are non-existent where I live so I am thinking the 1024X would be a good mid ground option. What would you do? Thanks!
