What strange combinations of equipment have you ended up with in front of the amp? Right now I'm using a Barcus Berry transducer. It's funky because it terminates into an RCA plug. The Pickup comes with a Buffer/Preamp with an RCA input (that makes sense) and a 1/4" output (normal). But the preamp was put together very badly. A microscopic spot of solder holds the inputs and outputs to the little board. After a little while I could no longer repair the preamp. But that didn't seem like a reason to throw out the pickup. So I got an Aguilar DB924 outboard preamp (18V MOSFET) and the appropriate cables and adaptors. I'm having a natural attack of G.A.S. and I think I want something like the Golden Trinity/Bass Max. But I don't want to retire the Aguilar.
