Robert J. Reina has posted a review of the Audio Research Reference 75 power amplifier ($9000) at Stereophile. His conclusions:
“The Reference 75 touched me on a deeply personal level. I enjoyed listening to music so much through it that every time I entered the listening room and saw its silvery hulk beckoning to me, I turned it on and played some music. More than with any other component I’ve reviewed, when the Ref 75 was in my system, I went out of my way to make sure, every chance I could, that music was playing.”
