Some of you are bringing stories about your wives and sound. OK, here is mine:

Recently I have been asked to measure and test several "audiophile" link cables. I have connected one of them into the system, and later started to listen to the music. My wife has immediately told me: "You have made some change in the system, haven't you? It sounds different!"
She did not like the new sound as well as I did not like it.

So this is my recent story about link cables. I am not telling the manufacturer - well known one.

Well one of the things we make around here for a select few are buffered guitar cables. Two versions, one has an fet follower in the Ax end plug to send the signal with a bit more ooph and the other has a driven inner shield.

Both make a difference. The preamp of course reduces the pick up coil inductance interactions and the active shield reduces capacitance.

(Difference is defined as measured and heard FYI)

Damn it Scott! Now I want some of that welding cable. I'll settle for the 6 gauge twin.
RADAFLEX® #6 AWG Twin Cable

Actually, I have some about that size (it's blue). It pulls my poor little amp right off the table.

Remember, my main purpose is to provide 150A from our island shed so my wife can run an apartment sized washer in the house. I drew line at providing enough juice for a dryer.

BTW I will have the speakers on Tuesday.

Excellent, let me know what bits you need to get them running.

well imagine that - audible differences where engineering theory predicts differences way above DBT/ABX frequency response thresholds

no one wanting intelligent debate has ever said no cable, transducer ever has an audible effect - when there are engineering reasons, clear frequency response variations

Lets see a pick up coil with an inductance of 4+ Henries of inductance driving a cable of say 750 pf of capacitance into a 2 megohm load. Where do you think the 3 db rolloff point would be?

you are so sure I'm contradicting you?

try reading more closely

double negative problem? - try: some cable, transducer combinations do have audible effects - from measureable frequency response variations Above published DBT/ABX thresholds

high inductance guitar pickups, practical cable, preamp input Z are exactly such a situation
