Enjoy superb sound from your favorite analog and digital sources with the Marantz PM7005 integrated stereo amplifier. Featuring a high current discrete power output stage with current feedback (a Marantz innovation), the PM7005 is also equipped with our exclusive HDAM technology, employing proprietary circuit modules with discrete components that deliver ultra-wideband response and fast slew rate.
The versatile PM7005 features multiple analog and digital inputs, including optical and coaxial digital inputs along with a USB-B 2.0 for direct connection to computer high resolution digital audio sources. Featuring the reference-class CS4398 high resolution D/A converter, the PM7005 can decode high resolution digital audio files up to 24 bits and 192 kHz sampling. It's also compatible with DSD 2.8 MHz and 5.6 MHz high resolution files (the same system found on SACD), and the asynchronous USB-B port also features jitter removal for the most pristine sound quality.
There are multiple analog inputs, including a MM phono input, along with dual recording inputs and outputs, and the Source Direct function bypasses the balance and tone controls for the shortest signal path, while the Analog mode disables the digital circuitry when listening to analog sources.
