Sidebar 3: Measurements
Measurement-wise, Conrad-Johnson's Premier 16LS was very similar to C-J's Premier 17LS, which Brian Damkroger reviewed for Stereophile in May, in that many of its "static" parameters varied with the setting of the volume control. Fortunately, because of the very high voltage gain—a maximum of 26.6dB, due to the lack of loop negative feedback—the volume control will be used in a position where things are basically okay. Fig.1, for example, shows how the high-frequency rolloff changes from when the volume is set to its maximum, "99" (lower traces), and to the unity-…
Jonathan Scull wrote about the Series 2 Premier 16LS in April 2002 (Vol.25 No.4):
Conrad-Johnson's Premier 16LS preamplifier and Premier 15 phono stage were recently upgraded to Series status. Like the Series 2 Premier 15 that I reviewed in our March 2002 issue, the changes to the 16LS include the use of faster diodes in the main power-supply rectifier and the main regulators are replaced with higher-current jobbies with a quarter of the "on" impedance, according to C-J's Lew Johnson. In addition, resistors that C-J had felt to be "noncritical" with respect to sound quality were found to…
Since 1992, Stereophile has recognized components that have proved capable of giving musical pleasure beyond the formal review period by naming its "Products of the Year." These are the components that can be recommended without any ifs or buts, that will grace any system in which they used.
There are five individual categories: Loudspeakers (including subwoofers), Amplification Components (preamplifiers, power amplifiers, etc.), Digital Sources (CD players, transports, processors), Analog Sources (phono cartridges, turntables, tonearms, FM tuners, etc.), and Accessories (everything else…
