Marantz PM8005 Integrated Amplifier - Black

This fully discrete current feedback integrated amplifier is perfect for audiophiles wanting both excellent music quality and flexible operation.

It offers a powerful 2x 70W into 8 ohm, while the symmetrical circuits ensure perfect image balancing. To guarantee a totally unique audio experience, Marantz designers have shaped and optimised the power handling characteristics and redesigned the large double shielded Toroidal transformer’s circuitry to optimise bandwidth power. The result is a current feedback amplifier with a massive energy reserve to drive even the most demanding of speakers with absolute ease. To further guarantee best sound quality, the PM8005 has current feedback HDAMs, as well as a triple-layer bottom plate to help eliminate vibration. The PM8005 also provides source-direct mode for the purest audio signal and Phono MM to enjoy your vinyls. It’s heaven.

Current Feedback amplification is a well known, Marantz’ original circuit technology. The Current Feedback amplifier technology fits perfectly with the high requirements set for Super Audio software providing wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited resulting in a very low phase shift. Marantz receivers and amplifiers equipped with Current Feedback can keep the phase compensation via Negative FeedBack (NFB) to a minimum, resulting in high through-rate, excellent transient response and superb sonic transparency for the full bandwidth. Unlike conventional Voltage Feedback amplification, the Current Feedback amplification makes the power amplifier in-sensitive to difficult loudspeaker loads.
Specifications:

On paper an electrical component might look excellent but the result may fall short of the combined design expectations. Marantz selects the appropriate components for the specific design application. In some cases it’s simply not possible to use standard components that meet the high Marantz standards. These components will then be specially made for Marantz in close cooperation with the Marantz engineers.

Marantz developed its own discrete circuit boards to replace standard IC's. These HDAM's consists of discrete surface mount components with short mirror image L/R signal paths. Those devices are doing exactly the same thing as the Op-Amps, but outperform the regular IC Op-amps dramatically in terms of the Slew Rate and reduced noise level, resulting in a much more dynamic, accurate and detailed sound. Over the years Marantz developed different types of the HDAM to improve quality and to fit to the special requirements of a product category like CD or amplifier.

Power Amp Direct extends the flexibility of an integrated amplifier for use within a stereo set or as a power amplifier within a multichannel set up. With Power Amp Direct switched off, it acts as a normal integrated amplifier for enjoying perfect sound quality in a stereo set up. With Power Amp Direct switched on, it uses the power amplifier for driving the front left and right speakers within a multichannel set up, using the surround channels from your AV receiver. What’s more, it does all this with a single push of a button, without changing wires. The Power Amp Direct can also be used for a stereo bi-amping set up.

A Shottky diode is a special type of diode with a very low forward-voltage drop compared to normal diodes. This lower voltage drop translates into higher system efficiency. Shottky diodes have very fast signal handling, can easily stay higher temperatures and are sensitive very low voltages.

Toroidal transformer has several advantages over a normal EI core transformer. It is very efficient and therefore delivers more power compared to the same size of an EI core transformer. In addition, due to its shape, the electromagnetic radiation and the mechanical vibration are extremely low all ending in a better sound quality.
