Audio Research – Reference 2 MKII Silver Tube Line Preamplifier w / remote
This highest level of resolution and musicality has been accomplished in large measure by all-new audio and power supply circuits, incorporating tube rectification (via one 5AR4) and tube regulation (via one 6L6) of the power supply (also packed with the newest Infinicaps, and one 6922). Gain is provided by eight selected 6922 twin triodes, like the REF1. Redesigned toroid transformers also contribute to improved dynamics. 19″ (48 cm) W x 7″ (17.8 cm) H (standard rack panel) x 15½” (39.4 cm) D. Handles extend 1 ½” (3.8 cm) forward of the front panel. 31.2 lbs.
