DVA R2X single-ended to differential converter

The DVA R2X is a single-ended to differential converter (i.e., unbalanced to balanced converter) for audiophiles. It's the perfect solution for using single-ended preamps with differential (i.e., balanced) power amplifiers, including our own. It has one stereo pair of RCA input jacks and a stereo pair of XLR output jacks. It has a gain of two (i.e., one volt input will yield two volts output) and a maximum output over 20 volts (zero to peak). Audio circuits In designing the DVA R2X, we prioritized the needs of typical audiophiles over the pro-audio requirements found with similar solutions. No options were off the table, including expensive transformers, purpose-designed IC solutions, and our own custom architectures. In the end, the solution we found to be the most transparent for most audiophile applications was a relatively simple custom circuit using carefully selected high-performance audio opamps. The result is incredibly clean and musical conversion for situations that don't in
