Which speakers / loudspeakers do you use and which are compatible? The Marantz NR1510 only has 50 watts of power at 8 ohms. You can hardly find any speakers for it. An amplifier should always have MORE power than the connected speakers! We recommend 1.5 - 2 x more power. I have just destroyed my Denon AV receiver after about 10 years because I have been running 150 watt floorstanding speakers on two 100 W channels for 10 years. Both front channels are now dead as a doornail (burnt out). Sometimes there is still a small pip. That's it. Within about 2 weeks, both front channels have burnt out after more than 10 years of such use. All other channels are still working perfectly. I didn't realise that speakers that were too big would destroy the amplifier. Now the problem with the Marantz NR1510: It only delivers 50 watts at 8 ohms and supposedly 75 watts at 6 ohms. I can't find any decent speakers for it! The speakers would have to be SMALLER. So a maximum of approx. 30 - 40 watts for 8 ohms (preferred) or approx. 50 watts for 6 ohms. Speakers that small are all RAMSCH. Cheap speakers with soldered speaker cables or active speaker boxes for PCs. Most decent hi-fi speakers only start at around 75 - 100 watts. Hence the question: WHICH SPEAKERS are you using with your Marantz? Are you aware that speakers that are too big will overload the amplifier and significantly reduce its lifespan? I want decent speakers that can be connected with banana plugs.
