MIT cables for Spectral amps ?


I just bought a Spectral DMA 200 power amp. After reading the manual, it recommends using Spectral/MIT cables for optimal performance. Is this really true ? Would I damage the amp using other type of cables ? I currently own Cardas Quadlink interconnects and Cardas Hexlink speaker cables. I have a Threshold FET 10/e pre-amp and Thiel 3.5 speakers. Any help on this would be really appreciated.

MIT cable is specified because it ensures that the amp will see a stable load at all operating points. The reactive charactaristics of the load can cause these wideband amps to become unstable (oscillating at above-hearing-range frequencies so you don't even know about it) until the amps' output devices fail. The MIT cable networks are parallel across the load, acting similar to a Zoebel network across the actual drivers, thus enhancing amplifier stability. I don't know how Spectral can determine what the failure mode was after the fact, but they definitely do know. Sometimes with certain combinations of speakers & cables you'll get lucky though. Up to you to determine if taking that risk is worthwhile.
