The Artemis Labs DP-2 Power Amplifier is a purist design. It uses the
classic 2A3 directly-heated triodes in push-pull class-A with transformer
phase splitting. Careful power supply filtering and regulation of critical
voltages ensure stable, quiet operation.
Given that the DP-2 amplifier puts out about 10 watts per channel, it must be
used with relatively efficient loudspeakers. The minimum efficiency required
depends on many factors including room size, room absorbtion, preffered listening
levels, etc., but in general, an efficiency of 92dB or higher per watt at 1 meter
is needed. Work with your dealer for the best speaker combination for your listening
set-up.
The DP-2 is conservatively designed and is built to last for many years. The
only maintenance needed is the occasional replacement of tubes. Please read this
entire userˇ¦s manual so that you can understand all the features and get the
most from the DP-2. The Warranty is on a separate card. Read it and send it in
to get full warranty coverage.
