Marantz SM500 Power Amplifier - Audiophile and Rare. Incredibly rare in this country, this is a superb Power Amp. Lovely sound and very cool looking too. It’s in very good condition for the year and receives high praise on Audiokarma. There weren’t that many of these made so it’s certainly a collectors piece. All fully functional with a full and detailed soundstage. Specifications below: Power output: 80 watts per channel into 8? (stereo) Frequency response: 10Hz to 80kHz Total harmonic distortion: 0.05% Input sensitivity: 0.5V Signal to noise ratio: 110dB Speaker load impedance: 4? (minimum) Dimensions: 426 x 145 x 356mm Weight: 9.3kg Year: 1994 With these being so rare I do not want to post out unfortunately (unless the buyer wants to take the full risk of damage). However, I will package to within an inch of its life though).
