The live PA I have been playing at gigs for the last year is based around the ESX-1`s
I just take my loops produced em real phat in the studio and then drop em into the ESX`s.
The valves make em sound so hot, the sudden jump in sound quality really notices when you play after a DJ. It`s super warm, super crisp.
I love em. I truly have loved playing a PA on them, if there are any questions you have about the ESX1`s then let me know.

An added bonus is that they look a hundred times better than a laptop and there is plenty of nobs and stuff to play with.

They have certain limitation, but for solid, thick techno, they are great.
