A macro view of the original RCA Victor interface on ‘Cassidy.’ At Steiner Audio, we believe the tactile experience of turning a vintage knob is irreplaceable. These controls have been meticulously cleaned, polished, and—most importantly—electronically serviced to ensure smooth, noise-free operation for decades to come. Whether you’re fine-tuning the volume or switching inputs for HDMI ARC or WiiM streaming, the interaction is purely analog. This is the hallmark of a true Memphis-made Steiner restoration. Quality you can feel.
