While staying with Radial, there is another option in the ProD2 (link here). It doesn't have the premium Jensen transformer, but it is still a premium product and I think it is much better value. You'll feel less guilty about kicking it around the floor - I had a JDI that I subsequently sold to a studio owner I know, as I was too precious about it to take it to gigs! Also, I suspect no-one in the world is going to notice the difference between the JDI and the ProD2 at a live gig.
thank you very much for everything.
your answers helped me a lot.
