The LS8 MKII is a pure Class-A circuit design with a large, fully-regulated power supply and is hand-assembled to the same critical standards as other Audio Research products. MKII component improvements include regulator FET devices, higher-quality resistors, Infinicap coupling capacitors and 6922 twin triode vacuum tubes. Mechanically, the MKII incorporates chassis isolation feet, extensive internal chassis damping and proprietary clear tube damping rings.
