Uneven speaker cable lengths and cable termination

Not necessary. At CES 2008 AJ Conti (Basis Audio) connected one speaker with a 6' length of cable and the other with 75' of cable.

Interesting. I do not find that surprising at all - given signals travel close to the speed of light. Provided the speakers and amp were a good match (speaker high impedance and amp low output impedance then even the very slight change in frequency response would likely be inaudible)

This is certainly worth our time to consider. Perhaps a blind test. Two speaker cables of equal or greater value compared to two of unequal length. Hmm. Is it happy hour. 75 feet is a little long. I don't think I have an out door extension cord that long and I have an electric lawn mower. Sometimes when the extension gets a kink in it the lawn mower stops mowing. I call the repair man.

Now you made me suspicious of this show - why would they need 75 feet of the speaker cable? Only one explanation jumps at me: It wasn't audio show - IT WAS ELECTRIC LAWNMOWER SHOW.

Ahochan: As far as the length discrepency - won't matter. The difference in electrical properties of the two different lengths is not significant. Sure there will be some difference in all three electrical values because they each depend on the length. But, the effect of these differences is unimportant in your application. The practical difference matters no more than, for example, whether the temperature in your refrigerator is 34 degrees F as opposed to 34.005 degrees F.

As far as connectors at the end of cables - does not really matter either. One can have problems with the connection between the cable and the connector and some banannas can result in poor connection at the male - female connection. You do eliminate these potential problems by going with bare wire. Of course making good crimp or solder connections and unplugging and plugging the banannas every six months also ensures no problems. But, there is no significant advantage to using spade or bananna termination - so no reason to spend the money if you are on a very tight budget.

Tradespersons and reviewers heard no difference.

I was there, you weren't kijunky and soundsreally.

Accept the facts and move on to something with which you've had more actual experience. Obviously it's not audio.

Perhaps lawnmowers are your calling.
