I was searching for a P.A: that fits my car and that allows me to play in most situation like teathers, club and private rooms! 
I had the chance to go to visit Schertler factory in Switzerland. I brought my pedalboard and my guitars. I tested the sound coming out from their amps and i fell in love with the Arthur prime 5 and with the Elyps 1000dw P.A.
The non negative feedback allows me to contain the resonance due to the phasing issue and with lower volume my music is able to spread in the environment in a such cool way. Details and dynamic are more clear!
