I use this cable to connect a Mesa Mark 25 head to a Mesa 212 cabinet. It great for that, the signal seems to go trough intact, no losses whatsoever.
More, the build of this cable looks very durable. It has double the thickness of a 'normal' cable, I would say it can survive a direct axe hit.
Finally,I think that it is a good investment in getting super good cable as you go and replace the ones that get broken - yes it is pricey, but then if you don't loose it then you have a lifetime of great sound integrity in front of you.
