Mark Levinson No. 532 Dual Monaural amplifier

I
am the original owner of this No. 532, it is in excellent condition and has
very low hours; original boxes/packing, AC cord, owners manual and XLR shorting
straps are included. It has been checked out from top to bottom by United Radio,
the Mark Levinson service center in East Syracuse, NY

The No. 532 was the
first non-reference Mark Levinson amplifier to be fully differential from
input to output.

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 <0.5% THD, full output from
2.59Vrms
