ARCing to new heights – As part of their 50th Anniversary product line improvements, Audio Research have a special edition of their LS28 linestage. "The improvements stem from what was learnt during the creation of the Reference 160 Series amplifiers. Very similar to the wire and parts changes in the REF6SE and REF PH3SE, the LS28SE even includes upgrading to our proprietary gold coupling caps."

Customers can begin upgrading their existing LS28 in July 2020.
