JDV Mk5 Specifications

The Radial JDV is unlike any other direct box made today. The absence of phase cancelling negative feedback in the front end combined with 100% discrete class-A electronics results in an astonishing clarity that is unmatched. The addition of switchable Jensen isolation transformers add yet another dimension by adding natural compression when pushed into saturation. The resulting tone can be observed in the FFT graph showing a warm cascade of even harmonics that will please even the most demanding audiophile.
