Marantz PM8100SA 69,800yen(2000 release)

Description
 
The Integrated Amplifier which inherited the design concept of PM-14SA or PM-17SA, and aimed at the correspondence to a next-generation audio.

It is possible to reproduce the multichannel sources including SACD or DVD-Audio by the DVD input being equivalent to a six-channel input, and adding power amplifier.

The Puri Power independent stream composition is adopted and high-quality sound-ization is attained.

The newly developed current feedback type is adopted as all six channels at the preamplifier part. This realizes a low-noise high slew rate, and reservation of the accelerating and dynamic range which can respond to a next-generation audio is aimed at.

The motor-drive 6-unit volume of a die-casting frame which has less deflection between channels than the conventional volume and whose performance is higher than an electronic volume is adopted as a volume.

The current feedback type is adopted as a power amplifier part. A phase compensation is also light by lowering a feedback impedance, and high speed amplifier is realized.
Moreover, have adopted the L-A-P-T transistor excellent in the high region property as a power device, a heat sink on either side is made to become independent, and the oscillation and the thermal crosstalk are reduced.

The super ring-core toroidal transformer, the "shot key barrier type rectifying device" low-noise in a high-speed and a low loss, etc. are adopted as a power-source part.

The standard newest model by German WBT is adopted as a speaker terminal as an SA series Integrated Amplifier, and the banana plug and Y lug are also supported.

The intensity of a chassis is raised, while having adopted as a chassis the double layered chassis which added the bottom plate of the 1.6mm thickness of a wall thickness steel plate and reducing the influence on the tone quality by the oscillation from the outside.

The compact disk&DVD direct input directly linked with a preamplifier part by exclusive relay is carried.

The full REC serector with the Lec buffer is carried.

The gilding treatment is performed to the input/output terminal.

The inlet type AC cable is adopted.
