    Analogue Tone
    Though digital technology and software have made great strides in recent years, Warm Audio still believe that nothing compares to the level of articulation, depth, realism, and responsiveness of a well-built piece of analogue gear. When you hear the bottom-end presence and top-end detail of quality analogue gear, the difference can be astounding. The cost of most boutique analogue equipment is financially out of reach for many recording artists. Warm Audio's mission is to change this, and introduce as many people as they can to recording and mixing with real, dedicated hardware.
