It uses HDAM: Hyper Dynamic Amplifier Mumbo-jumbo. Tuned by the Marantz Stare Master. https://www.marantz.com/en-gb/shop/amplifier/model30 The fancy brushed face plate is sure to compliment any bar. Would be perfect with the Mag Lev turntable. Who cares if its loaded down to 390 ohms? Just look at it! Feel the knobs! Ooh! Getting a little now just thinking about it.....
