I'm a professional musician and audio engineer with 20 years of experience working in music for a living. I tour 100-150 days a day and operate a small home studio. Needless to say, I've used quite a few DI boxes over the years. Quite honestly, these Proreck DIs are just as good as passive DIs you find at quintuple the price. I've now been using one regularly for the past month and I have no complaints. They're built rock solid, seem very transparent, they're reliable, they're light weight and the footprint is on par with any passive DI from leading brands. I will likely be ordering more and recommending them to my peers!
