A power amp to be fitted in the rear slot is due to come out very soon, keep saving 
Hi William,
as Guitarnet70 says, the KPA is a digital preamp and requires - like any modeller: Pod, Axe-Fx, 11R - a poweramp to properly drive a cab. It can go straight to a mixer or a PA tho, and will sound gorgeous with every acoustic guitar amp, bass amp or keyboard amp - as long as they are good amps 
You can actually even use something as simple as an EHX .22 or .44 caliber which are power amps in a pedal enclosure.
Can you guys confirm whether or not a Matrix GM50 fits the KPA's rear niche? At least to be carried.
Matt at Matrix confirmed that the GM50 does not fit at the back of the KPA 
Is the GM50 a 50watt SS?
My buddy uses his pedalboard through a Marshall MGFX100w SS in a 400 seater and it's just enough, in a bigger venue the 100w SS clean tone falls apart.
I wonder what wattage the KPA SS poweramp is going to be?
Needs to be 100w minimum...
Needs to be 100w minimum...
It also depend from the impedance....
