After all of the experimenting with speakers, amps ,preamps,powered monitors,microphones, mixing boards and the like , here is what makes the most sense, least hassle,most direct signal chain and hopefully most reliable set up.
David Gage Realist
Troll Ribbon Mic
Acoustic Image Ten2 S4 plus
The Acoustic Image Ten2 S4 plus is compact, has every feature known to mankind, independent EQ, great sound.
While the Headway EDB-2 was great for the Realist, there was no independent EQ for the Troll and required another power source.
While mixing board and powered monitor was good ,too many cables,connections and power sources.
I considered the Flex Preamp to use with the Genz Benz but then again more cords ,connections and signal chain devices and the Ten2 cab sounded tighter and more focused

Bergantino CN212 and Kustom KXB500 for electric
