The front panel has the inset Audio Research logo with an engraved line completing the panel, but no handles.  There are simply two switches for Power/Off and Mute/Operate. The entire chassis is silver, and the front panel is only available in Nat...[more]

Since its introduction in 1999, the LS16 has been a best-seller, combining a relaxed, engaging musicality with good flexibility and connection options. So why change a good thing? Well, the enhancements introduced in the Mark II versions of both the Reference 2 and LS25 have proven so popular that we feel it is time to incorporate many of the same technological improvements into the LS16MKII.Funct...[more]

On the front panel, the changes are more obvious. A new linear LED display provides a 20-lamp display for the 104-step volume control, as well as indicators for selected input and muting. One rotary control is provided for volume adjustment, while a second controls input select. Pushbuttons are provided for power, monitor, processor (unity gain) and mute. All functions are also accessible via the ...[more]

The LS17 SE maintains the same physical size as its predecessor.  The only cosmetic difference is the updated front panel which replaces the black plastic buttons with round metal buttons, complementing the symmetry of the two control knobs flanking the LED display.  The display shows volume as well as which input is selected.  Front panel controls include power, monitor, mute and p...[more]

The LS25 MKII vacuum tube stereo line preamplifier offers sonic performance, functional flexibility and value second only to the world-renowned Reference One preamplifier.
