I believe the issue is not that some amps oscillate with network cables but that some amps need to used with network cables to prevent oscillation. Hence the Spectral requirement to use MIT. Spectral is very high bandwidth, of the DC-to-light school of design. I have heard that the warranty on Spectral amps is voided if you do not use MIT cables, which, if true, strikes me as a bit arrogant. Dan Rubin.
Can speaker cables damage amplifiers?
I have been told on good authority that network cables such as TRANSPARENT and MIT can cause broad bandwith amplifiers (eg Krell) to "go into oscillation" and thereby cause some nasty damage. These cable manufacturers, apparently, are aware of this problem. Can anyone confirm this?
