According to the specification output power 2x60W or 4x30W. I have connected the small Teufel loudspeakers (Ultima 20). My device is located on the Riederalp in Valais.....
The device is far away: in Davos, & I'll soon be away for a long time. I'm not a professional, but I've connected my Piega speakers & I'm extremely happy. Compatibility with standard loudspeakers should not be a problem, & I can only recommend this Marantz receiver. I had paid considerably more!
