I am the original owner; this No. 532 is in very good condition and has very low hours, original and boxes/packing are included. It has just been checked out from top to bottom by the Mark Levinson service center United Radio in East Syracuse, NY.
The No. 532 was the first non-reference Mark Levinson amplifier to be fully
The Nº532 has two independent audio channels, isolated from each
other and from the control and power circuitry. This isolated
design results in two “piers”, each containing identical circuitry for
a single audio channel. The control and power circuitry resides in
the center of the amplifier, between the piers and thus isolated from
each audio channel. This unusual design provides a number of
advantages – additional heatsink capacity for thermal requirements,
virtually ideal balanced output characteristics, and the ability to
isolate potentially noisy power and control circuits from the signal
path of the audio channels.
The signal path is electrically identical for both audio channels and
contains no relays, capacitors, or inductors to minimize forms of
nonlinearity and maintain very low output impedance levels. The
compact design of the circuitry allows the signal path to be tighter
and smaller, reducing parasitic capacitances and minimizing
propagation delay and phase shift. The end result is a faster, wider
bandwidth and cleaner output signal with very low impedance level
and minimal signal degradation. Lastly, the audio signal output
path contains 24 output devices per channel – providing an
impressive power capability while minimizing crossover distortion.
The No. 532 is rated at 400W per channel @ 8 Ω,, 20Hz to 20kHz at
