The terroir thing got me thinking on a more serious—well, more relevant—note: I run Magnepan 1.7i’s off a pair of Vidar monos; happy with the setup and my use case has never caused the Vidars to go into protection. However I’m on a path to adding DWM panels from Magnepan; these are mageneplanar woofer (not sub-woofer) panels that are supposed to be added in parallel to the speaker cable circuit that goes to the mains. I’ll see how that goes, but I know that this is going to present the Vidars with a 2ohm load so they are more likely to complain.
I’m prepared (at least mentally!) to have to go with a separate power amp for the DWMs, I can run it from the SE-outs on the Freya+. Where the terroir thing comes in is, will an amp from a different manufacturer (I was thinking about an Emotiva BasX-300) change the overall signature of my largely Schiit-based system—enough that one would notice?
Obviously one could purchase a third Vidar for the woofers, but that’s starting to feel like overkill.
My fallback in the interim is to go with the two Vidars each in stereo mode, one for the mains the other for the DWMs. This might even buy me some time to wait and see what Schiit comes out with in new power amps to augment the current Aegir and Vidar models...
