Cables other than MIT with Spectral

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.

I agree with Flex and Detlef. The required use of MIT cable with Spectral only applies to their power amplifiers. However, I believe it is essential that you use Spectral preamplifiers like my DMC-20 with Spectral amplifiers. I too have used other than MIT cables without any detrimental effects with older DMA-50 amps. I recently have been using Virtual Dynamics cables with my Spectral DMA-50 amps and discovered something quite interesting. Prior to using these cables, I had been using MIT 750-plus speaker and MIT 330 interconnect cables. When using these MIT cables, the amps always ran fairly hot. After inserting the Virtual Dynamics Cryoed Audition power, speaker, and interconnects cables, I was surprised to find that the amps now ran cool to slightly warm. Rick Schultz had told me that this would happen, but I honestly didn't believe him until I ran his cables for a couple of days and touched the amps. It is quite remarkable, really, and they sound far better in every respect than the MIT cables I had been using.
