I'm looking for opinions on a rig I'm working on putting together. Here is what I have: -Modulus Q5, Rane DC24, GK 400RBIII, Avatar B210 4ohm -I play in a medium sized church where they LOVE being able to hear the bass!!!!!!! -I like a good tight sound, with lots of bass. I'd like to ditch the GK head and go with... QSC PLX1602, an Alembic F-1X or a Sansamp RBI pre-amp and then add a Avatar B115H or B212 using the PLX1602 in stereo to "bi-amp". Here's where my questions come in... - PLX1602 enough? - B115H or B212? - Can anyone compare the 2 pre-amps from experience? (Is the F-1X worth the extra $$$) - My budget is somewhat restricted (wife, 2 kids under 5, third on the way) so I don't want to have to buy/try/sell/buy.... I do understand that some of this is subjective and I do plan on doing some testing myself but with the 2 boys around and the wife not feeling well (can you say 1st trimester??) my time is limited AND I value your opinions!! Thanks for your input!!!!
