why use CAT5 cable?

Due to lack of a deep enuff background on the subject, i'm not able to comment on this. I will reproduce this graph of actual measures. If the phase can be related to time delay, and one can take the know human time displacement threshold and convert it to frequency (unknown), then one needs to look at these out to 50 kHz.



The supporting narrative is here http://www.t-linespeakers.org/oddsen...ittX/cat5.html (i have to fix the picture link on that page)

Dave,

It would be interesting to know the source and load impedance used for that test, and whether the source was balanced or unbalanced.

John,

I some thread here, Aaron went into more detail. I couldn't find it thou.

From the picture, looks like he tested CAT5 as-if it were Litz wire.
Didn't split out the ends as true parallel 100ohm transmission lines.
Maybe I'm misinterpreting what I see in the photograph?

12x 100ohm pairs (3 CATs) in parallel makes an awfully good 8.3 ohm
ladder network. I wonder how that would have scored in his test?

Then again, he would have needed a resistive load at the far end to
see L and C begin to cancel each other out... I can't think any easy,
cheap, or off the shelf way to measure that effect with anything
other than 50 ohm antenna analyzer. Which is obviously not gonna
measure properly into 8.3 ohms...

You could thus measure two pairs in parallel. but I don't know how
much that tells you truthfully about 12 pairs bundled in parallel?

Here is the 1st post on the methodology.

Do speaker cables make any difference?

well its a very informative lot of info here...benefits may just be subjective, and maybe better suited to FR speakers in SOME cases...i dont have FR speakers but posted here as there are some people here that have great knowledge or experience that arent into the multi-way thing. Some here like you dave, have a fist in every pie so to speak. Either way in many ways both fullrangers and woof tweeters people are often seeking the same goals, albeit in different ways and accepting different compromises. Got a bit of HQ CAT5 LAN cable here and might just try it---but since i have a 30watt SS amp and 2 way speakers of some 87dB/W, it may prove less impressive than the current cable i have, or i may be surprised; or even not notice any change at all.

food for thought at least, and an experiment. I WAS thinking of using lighter gauge for tweeters and heavier for woofers but that may NOT be a good idea, judging by the last posts

At short lengths is may work, but at longer lengths ot will choke the bass...

Hey, wire does make a difference. I went to friend's house that had just purchased an NAD integrated amp and a pair of B&W's. Really sounded like crap. (He thought it was great.) I took an audiophile friend over to his house and could tell by the look on his face he agreed. I ducked out pretending to get a Coke and went home to get a pair of Kimber Kables. HUGE difference over his patch cord. My only test instruments are a good DVOM and my ears. The ears gave a thumbs up!

Also, for yucks I made a set of cat five patch cords for a friend for Christmas. They were noticably better than his @#$%& Shack patch cords and not much different form the Kimbers. I used three strands, two for gound and one for positive and wound by hand, ala Kimber. Next I plan to try them as speaker cables. Don't knock it till you try it. My audiophile friend is a union teladata tech. Read free cat 5 remnants.
