There's been much discussion here and many other forums about the so called 'exotic' speaker cables and the effects on output stages in certain amplifiers. From what I understand some amplifiers can go unstable at high volume when connected to these cables with resultant s/c output transistors etc.

Is there a problem with the design of the Zobel network in the amplifier, insomuch that the low resistance and possible capacitive effects of the 'exotic' cable
cause it to 'take-off'?

I read about this on and off over the years, and some high-end amps seem quite prone to damage in this way. But few explanations really go into any detail about exactly what's happening.

Anyone fancy a write up or a link to good article somewhere?
