In the August / September 2005 issue (155) of The Absolute Sound magazine, editor Wayne Garcia reviews the Artemis Labs vacuum tube based LA-1 Line Preamp and PL-1 Phono Pre-Amps. In the article Mr. Garcia describes his listening experience with the LA-1 and PL-1 as "spine-tingling." He also comments on the design and construction of the units. For review details, please refer to issue 155 of The Absolute Sound magazine already in distribution.
A New Purist Vacuum Tube Phono PreAmp for Low-Output Cartridges Artemis Labs PL-1
The Artemis Labs PL-1 Phono Preamplifier is the result of several years of perfecting a simple yet extremely high quality tube-type preamp. High quality parts are used throughout and the design is rugged and reliable. The sonic qualities: tonality, detail, smoothness, and presence are outstanding. The PL-1 is optimized for low-output moving-coil cartridges. See information on the Artemis Labs PH-1 for a preamp optimized for medium- to high-output cartridges.
Artemis Labs PL-1 Tubed Phono Preamp Features:
70dB of gain with low hum and noise:
High-quality step-up transformer gives good hum and noise rejection.
TexTool™ ZIF socket connected to step-up transformer secondary:
Allows any shunt loading resistor or capacitor to be effectively attached to step-up secondary.
Three stage design with passive RIAA equalization:
Equalization is flat within +/- 0.2dB from 20Hz to 20KHz and is flat to +/- 0.5dB to 40KHz.
Last two stages have gentle feedback and can drive as low as 8K loads without the use of cathode followers.
All key audio circuits wired point-to-point using military-style terminal boards:
Sonic degradation due to fiber-glass PC boards is minimized.
One 6N1P tube, two 12AX7/ECC83 tubes and two 5687 tubes. All but 6N1P are run in Cool-Swap™ Configuration:
An idle spare in each tube, plus tubes run cooler.
Choke loads for each triode:
Allows tubes to run in their most linear mode and permits lower plate supply voltage
Low-Gain MOSFET high voltage regulation:
One regulator per channel minimizes cross-talk and gives a firm, stable sound without sounding “solid-state”.
All Artemis PreAmps Designed and built in the United States using the best parts from around the world.
