I once owned an Audio Research amp and CD player. Nice stuff but, frankly, not smart purchases. Apparently others have come to the same conclusion.\n\n\nSorry, can't disagree more. I've owned various pre-amps, line stages and phono-pre over the past 40 years and have NEVER been disappointed. My SP-9 mkII, Steve Huntley(Great Northern Sound) modified pre-amp still lives and performs beautifully in my sons system out in the mtns of Colorado.\n\nMy LS-28 is my current line stage that continues to bring me listening joy !
