Topic: The zA2.1 Reference & History of the JansZen Electrostatic
The JansZen
zA2.1 Electrostatic speaker is a monopole speaker with dual 7
woofers aligned in the WTW configuration to minimize floor bounce
effects, $7495/pair. It also has narrow but controlled horizontal
dispersion to reduce first reflections from the walls. David Janszen,
the son of the original inventor of the first practical electrostatic
speaker, maintains that the 3 tall hybrid speaker delivers
all the advantages of a full range electrostatic speaker, a design
that remains the simplest, most linear possible way of moving
the air.
The brand. Since 1954, electrostatics have
been the standard bearer of high fidelity, and JansZen originated
the electrostatic. Davids father, Arthur A. Janszen, was
granted his patent in 1953 on that first commercially practical
electrostatic transducer mentioned above. In 1954, he founded
JansZen Laboratory and began manufacturing the first high fidelity
electrostatic speakers. Many are still in operation after more
than 50 years without service. A recent
review in Positive Feedback states the zA2.1 possesses the
best of both worlds; electrostatic panels that give off an amazing
soundstage with focus, clarity and realism; and bass drivers that
appear out of nowhere.
The speakers will be driven by Bryston PowerPac
120 amps; the source will be an exaSound e20 USB DAC served files
and CDs (but not SACDs) through JRivers Media
Center. The DAC can natively process DSD files up to 4xDSD (11.2
Mbps) and PCM up to 384/32.
We will have refreshments at 5:30
