Marantz Model 50 FB Integrated Pre-main Amplifier Black HDAM-SA2 

100V NEW

Description

・New generation Marantz design
A new housing created with a modern interpretation while inheriting traditional design elements.
・Full discrete preamplifier with newly developed low distortion HDAM
Low-distortion HDAM improves distortion by approximately 40% compared to conventional models
・Variable gain preamplifier equipped with HDAM+HDAM-SA2
Variable gain preamplifier circuit that greatly improves S/N ratio and spatial expressiveness
・Full discrete current feedback parallel push-pull power amplifier
Increased instantaneous current supply capacity to 66A, 145% of PM8006, greatly improving speaker driving power.
・Large capacity and high quality power supply circuit
Adopts one of the largest large-capacity toroidal transformers in its class and custom block capacitors (18,000μF/63V x 2)
・MM type cartridge compatible phono equalizer
Eliminate AC coupling capacitors and improve signal path purity
・Machined brass speaker terminal & input terminal
Robust machined brass terminals are used for the speaker terminal, CD input, and phono input.
