Timeless Marantz Craftsmanship & Design

The signature porthole display and subtle side-lit front panel evoke an era of classic hi-fi, while the robust copper-plated chassis and toroidal power transformer underpin a noise-resistant foundation for supreme audio fidelity.
Performance That Commands Attention
At the heart of the AV30 is Marantz’s famed HDAM-SA2 discrete amplifier modules paired with Current Feedback topology—delivering dynamic, ultra-low distortion performance across your entire soundstage.
