We are pleased to offer another Reference Classic,
The Audio Research REFERENCE 2 Balanced (2) Channel vacuum tube Line Stage
Gently used One original owner, beautifully cared for by a long time 2 channel Audiophile client of ours Smoke-free, pet-free environment
There are not enough superlatives to describe the performance of the Ref 2.
This is what one reviewer had to say, to sum it all up...performance above the bass was also subtly more vivid, warm, and harmonically enriched than the incoming signal, but only slightly so: full bloom, no stem rot. The result was a coherent, fertile, BIG picture—
...Dynamics at both ends of the scale were among the best I've heard, rivaled only by the Sharp SM-SX100 digital amplifier: explosive at the loud end, nuanced and capable of revealing fine gradations below. The Ref 2 never unraveled on orchestral crescendos, maintaining spatial and tonal integrity. Its rendering of small-scaled, delicate dynamic movement gave life to some recordings that previously had seemed to fade into a glaze as the musical detail descended in level. The Reference Two delivered this sensation of living music even at relatively low volume levels.
