CTA305

For low level voltage amplification, valves are in a league of their own with respect to linearity and musicality.  For nearly a decade, COPLAND has contributed to the refinement of amplification using these classic devices. The CTA 305 employs reliable E83CC valves selected after ageing to assure optimal compability.             Each class A lin...[more]

JPL

JPL  The sober and elegant JPL monoblock preamplifier, its protective grill and the height of the face plate masking its component parts, never fails to arouse our curiosity through its discreet appearance. This preamplifier is made up of three 12AX7 double triodes. The gain , of about 35 dB, is supplied by the first two tubes mounted in series. The last tube is used as a cathode follo...[more]

LP 1

The LP1 is a departure for us in both size and series designation. The chassis is a compact 13” wide, by 8.6” deep, by 4.5” high. 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]

LS17SE

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]
