For the PM6003 Marantz took the opportunity to not only change the cosmetics of it’s much appraised predecessor PM6002 to get it in-line with the M1 design, but even extend the quality. It got special treatment to refine the sound and optimise the balance from bass to mid to highs for a performance full of harmony. The new lower impedance case shielded toroidal transformer was matched to new main capacitors which again have been aligned to a new type of power transistor capable of handling higher current and keeping better control over the speaker. More powerful transistors are mounted on a new extruded aluminium heat sink reducing resonances which could influence the sensible audio signal. All has been balanced and harmonised with the right combination of customised audio components on the right place of the circuitry. Tight bass, clear stereo image and a wide sound stage is the result. Be amazed!
