JDV-Pre Specifications

The Radial JDV-Pre is a ‘character’ product. In other words, although the specifications are important, only by listening to the JDV-Pre will you come to appreciate its true value. For instance, eliminating negative feedback for a more open sound is a trade off that will increase certain types of distortion. Building products is always a matter of compromise. One of the important specifications here is the FFT (Fast Fourier Transform) that shows the even order cascade of harmonics and the resulting warm Bessel curve. This is often considered to be the primary indicator of a good sounding circuit.
