Have the 100.2. Was recommended by Marc Mickelson, a reviewer with Soundstage at the time I bought his ARC Ref3 and PH-7 through Agon (now with Audio Beat). Love it. Has very limited negative feedback. Unfortunately I think it is now on the list of ARC gear they will not repair as some resistor is no longer available. Regret having sold my Ref3. Warm musical darker sound signature. Currently looking for used ARC preamp, likely 5SE, but appreciate this thread and input above.
