Audio Research continues the tradition of advancing state of the art in music reproduction with the introduction of the Reference Phono 2 SE preamplifier. Using component technologies derived directly from the acclaimed Reference Anniversary preamplifier, the Reference Phono 2 SE provides substantial sonic enhancements beyond its predecessor and brings the listener closer to the music than ever.
OVERVIEW
Fantastic condition trade-in Audio Research REF Phono 2SE in Silver finish.
Phono preamplifier comes in original box and packing with remote control, power cord, and printed owner’s manual.
Preamp is rated 8/10 for minor cosmetic wear consistent with age and use, including a small nick on top panel corner (see photos).
