Since their introductions in 2015 and 2019, the Reference 6 and 6SE preamps have offered unparalleled levels of performance, and remained Audio Research's best selling products. In 2024 the Reference 330M offered a dramatic new benchmark in amplifier performance, challenging Audio Research to create new preamplifiers that offered similar breakthroughs. The new REF7 takes what Audio Research learned in the development of the 330M amp to dramatically engage the listener with its clarity, finesse, dynamics and sheer musicality. There is a new gravitas in its presentation, both musically and physically, with a new single chassis design that is more refined and elegant. Accepting pre-orders now with a retail of $28,000. Circuit Isolation: Uses extensive dampening and isolation methods to eliminate tube ringing and unwanted internal resonances. Volume Control: Employs an advanced resistor ladder-based control system for precise and quiet adjustments. Touchscreen Display: Features an intuitive, modernized front interface. Performance: Surpasses the sonic capabilities of both the older Reference 6SE and the former flagship Reference
