Acoustic Zen vs. Coincident CST

Thanks Israel. I may indeed have the wrong end of the stick - but I have found that a very few amps do react badly to medium/high capacitance cables, despite low resistance and inductance. Perhaps my experimentation is not sufficient to identify the actual causation. I must emphasise that despite experimenting with many amps I have only come across two that had a problem with high capacitance cables.

Cable capacitance may be relevant in cases where circuit impedance is high.It is therefore not recommended to have high cable capacitance on the output circuit of a preamp with a source impedance of a 500 ohms or higher.The output circuit impedance of a power amp is ,however,very low,usually in the range of .1 to .5 ohms which is far too low to be affected by the shunt capacitance of even the highest capacitance speaker cables.The only possible exception where high speaker cable capacitance could be audible would be the case of a high output impedance preamp being mated to a very high output impedance amplifier like a Sonic Frontiers(somewhere in the range of 6 - 10 ohms)connected to a low impedance loudspeaker.

Thanks Israel. We were using very low impedence speakers, and so that may have been the case.
