The Red DI is a rip off. Especially the new rack mount version. Plus I have seen with my on eyes how the customer service up at A designs can be and after that those guys will never get any of my money.
Plus Josh Broughton has a product that simply smokes the reddi.
I don't think flaming A-designs is what this thread was created for... I'm sorry you don't like their products. There are enough big name players and engineers with extensive resumes out there using these over everything else for a reason. A couple have posted in this thread.
I don't have even CLOSE to the resume of Reggie or Kirk, but I play for a living and the REDDI is a big part of my sound live and in the studio. Is it for everyone? No, everyone has different needs. For me its invaluable. It slots the bass just perfectly in the mix without getting in the way of the other instruments. And IME Peter at A-Designs is absolutely fantastic to deal with.
