About the Differential Design Stack
The Emotiva Differential Reference Design Series Stack is a complete high-fidelity audio system comprising four matched components: the DRS-1 Streamer, DRD-1 DAC, DRP-1 Stereo Preamp, and DRA-1 Power Amplifier. Each component shares identical compact dimensions (10.5"W x 10.25"D x 2.25"H) and weighs 5 pounds, allowing them to stack neatly on shelves or furniture without requiring a traditional full-width rack. The system is engineered with a fully balanced (differential) signal topology throughout, designed to reduce common-mode noise, improve channel separation, and preserve low-level detail. All components feature balanced XLR and unbalanced RCA connectivity. The complete stack includes a cable kit with XLR, trigger, and digital coax cables, providing $400 in savings versus purchasing components individually. Individual components are also available separately.
