Great high end Marantz set with nothing but very positively rated PM7001 & SA7001, rarely offered as a set!! Both components were designed to work together and this is definitely hearable. The amp has a dedicated circuitry for the CD/SACD to even further optimise sound quality. As for the design, there is complete engineering feng shui. Blocks have a symmetrical amplifier circuit topology that, according to developers, allows to achieve perfect balancing of the stereo image . Also used in the design of branded modules HDAM, designed to keep intact the dynamic structure of the music, its tone and the stereo image.
