I think Merlin recommended the Cardas Golden Cross or Golden Reference because of the internal wiring, but it also helped to flesh out the low end on the older VSM-SE design. The VSM-M design does that on it's own, so the "M" version would probably sound good with the Neutral Reference or something less "warm". As always...it depends on all of your other eqipment. I don't think there's any reason you need to use Cardas for Joule amps.
Has anyone heard the Joule Electra Stargates?
I saw the Stereophile story on them, they look interesting. I have Silverline Sonatas, they are fairly efficient so I don't need a whole lot of power. Opinions please, I am looking at these amps and would like any opinions before I take the plunge. Thanks!
