What amp for my LCR


Recommended Posts

Since a few months I updated my Onkyo TX-NR676 into a Marantz SR7012.

And now I wonder if it is worth the money to go for an external amp for my LCR?

My LCR are RP600M and RP500C, all three speakers 100 watt RMS and 400 watt Max.


The Marantz SR7012 has in 2 channel driven 125 watt per channel at 0.05% THD.

In 5.1.4 configuration this is minimum 70% of that value, guaranteed by Marantz, so that would mean 87 watt per channel at 0.05% THD.


So for music listening in stereo configuration there is a little headroom in the SR7012, with its 125 watt and the 100 watt RMS from the RP600M.

But in full dolby movie watching the 87 watt is a little low to get the full potential.

Not that I watch movies that loud, but it might be nice to have a bit more headroom there and also release the SR7012 internal amp's from some duty.


All help and thoughts are more than welcome!
