That was the point, he got his sound by profiling his rigs...
I have also found that the KPA has made me think differently...that I don;t need to feel my sound on stage, hence I don;t need any analogue stuff, because it took the KPA to make me realise that the most important "consumer" of my sound is not me or even the band, but the audience. Hence my focus is FOH now and monitoring is just for that - monitoring.
That's cool... I guess I'm a bit more selfish in that regard, meaning that I see myself as an equally important "consumer" of my sound on stage, because it inspires me to play better / differently or to enjoy myself more (which in turn might improve playing etc).
