Some speaker cables produce lower/higher volume?

You should use an SPL meter to measure the difference. Please report back.

Did you pull out the db meter?

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.
