Cables other than MIT with Spectral

I believe Goldmund recommends the same thing. Flex is right on the money. I have owned quite a bit of Golmund gear and Spectral including some Damien and Crosby modified gear a long time ago and was always told to use their cable or MIT. In fact I think MIT produced the cables for Goldmund.

Adding to Viridian's comment, I believe the same idea also applies to Spectral. That is, they also depend on the inductance of the speaker cables rather than including the inductance within the amp output stage.

Spectral equipment is very wideband & can easily oscillate ultrasonically (you won't hear this) until the outputs fail. Yes they can tell if you've attempted to operate otherwise & will absolutely not warranty this folly. Transparent is another networked design that *should* operate with full stability on Spectral but I wouldn't guarantee anything. Unless you have a quality oscilloscope bridged across a Spectral amp's outputs, or a lot of expendable $ & time, then DON'T.

Flex and Bob are absolutely correct in this. However the caveat, according to my experience, does not apply to older Spectral gear. I've run their 200s with all sorts of wires, also the 50s without any detrimental effects whatsoever.
