Hi folks
I have another ignorant tech question that I hope you'll be able to help me with...
I am lucky enough to have a NAD M33 and a pair of Martin Logan Motion 40is. They make a very cool pairing - all sorts of lovely.
But I like the whole thing even more when I add a second pair of speakers - a pair of Monitor Audio Bronze 5s. (Nowt special on their own, but when bass port plugged, they add considerably to the sense of wide soundstage for the whole shebang.)
My question: am I doing any long term harm to the amp by running both pairs of speakers simultaneously? The MLs are 4 ohms, and the MAs are 8. I ran them both together for a couple of weeks and kept watch on the handy temperature readings that the NAD has. It didn't seem to be stressing the amp (at least in temperature terms).
But then I took out the MAs, cos various reading that I did suggested that the setup could be harmful to the amp in some way.
So, could you help me understand: (a) am I doing harm by having that 4 ohm/8 ohm combination running simultaneously? (The NAD has plenty of power - 400w into 4 ohms, it claims). And (b) if I am, could you help me understand what that harm is? (I have no real understanding of the physics or engineering involved, but I'm a reasonably quick learner...)
My best guess was that putting that load on the components would cause them to wear out more quickly. Is that right?
Does it make a difference that the NAD is a class D amp? Does that make it any more/less likely that I'll be doing it harm?
Thanks for any increase in my dim understanding that you can help to create...
