Some speaker cables produce lower/higher volume?

yes, due to what counts the most: gauge. A good experiment is comparing canare 4s11 against canare 4s6 for example... same wire, different gauge.

I have demoed many speaker cables including clearday and those gave a midrange suck out which forced me to turn up the volume alot. The bass was more pronounced than many others I did not like them. Also one of the cables I had tried Granite audio which was a very good cable however all frequencies were louder than any other cable I tested. Over 15 different names. So your not trippin.

Thank you to all who responded; I appreicate your comments.

The electrical properties of a cable can also affect the performance; of an amp i.e. capacitance and inductance.

E.g naim amplifiers really like low capitance speaker cables and actually sound worse when used with higher capacitance cables. Naim also recommends a minimum and maximum length of cable to be used. Naim own speaker cables are among the lowest capacitance cables out there.

Also the inductance may also have a detrimental effect, but to a lessor degree.

High capacitance cables can also act as a filter that also affects the sound and possibly an apparent volume change.
