Reference Max Bundle (Reference + Protocol Max) [Pre-order]

ESTIMATED FULFILLMENT TIME: 2-3 weeks The Reference Max Bundle is a complete high-fidelity system built to unlock the full potential of your music; where precision tuning meets uncompromising power. Designed to work in perfect synergy, this pairing delivers a clean, authoritative signal chain that elevates every detail, from the deepest bass textures to the finest treble nuances. At the core is the CrinEar Reference, engineered for true reference-grade sound with a neutral, measurement-driven tuning that reveals your music exactly as it is. Its advanced 2DD + 3BA hybrid driver system, featuring the Horizontally-Opposed Dual Woofer System (HODWS), produces tight, controlled bass, natural midrange clarity, and extended, resolving highs, creating a sound that is both precise and immersive. Driving it is the CrinEar Protocol Max, a powerful portable DAC/amp that brings out the Reference’s full capabilities with greater resolution, dynamics, and control, alongside the ultimate flexibility of a 10-band parametric EQ. The result is a listening experience that feels effortless yet revealing, whether you’re in the studio or on the move. Together, they form a seamless, high-performance setup designed for those who demand clarity, accuracy, and impact in every note.
