Sorry for asking, I was only interested in your results.
Yes I did, I was able to identify four different cables of the same manufacturer, by name in 12 tests.
Yes, this is a 89410A Vector Signal Analyzer (VSA) up to 10MHz, current at HP until 2008 and still supported, yours is a 3563A spectrum analyzer up to 100KHz, obsolete since the late 80's. I have a 3562A myself, and use it mostly for low log frequency sweeps.
I use mine for resolution of the residual of ST analyzers, and for fine tuning RIAA networks.
Would anybody be interested in receiving a 70 centimeter "homemade" stereo RCA interconnect cable for testing for one month, after which you should mail me your secret review, and use a small amount of money on mailing the cable to the next reviewer. I would like 5 persons with diverse equipment and opinion on sound to sign up. I will after 5 months report on the listening impressions of this cable. It will be interesting, whether this test will give uniform or very diffferent responses.
Anyone interested can contact me by personal message. The listeners can be anonymous, if they like. AA = Anonymous Audiophiles.

See John? This is only apparently off topic, in fact is at least 50% of the problem.
How on earth could one prove something to you (or anybody in the GEB), when you are unable to admit errors even in insignificant matters like:
"I have a newer version of what Syn08 uses as his avatar on my test bench"
Cable test offer
It would be good to get some tests done and post the results to the forum.
So, lets try to organise something, for those of you who are in Sydney (Australia).
If you think there are differences in cables, I’d be prepared to bring some cheap interconnects and do the switching between the existing cables in your system and the cheap cables. The rules would be:
So, PM me if you want to do this. Either as:
Any takers?

If you think there are differences in cables, I’d be prepared to bring some cheap interconnects and do the switching between the existing cables in your system and the cheap cables. The rules would be:
- cables concealed so you can’t see them when we do the ‘X’ switch
- you must leave the room during switching
- random numbers used to decide which cable to use
- any program material you like, but the selection can’t change once we start
- you can listen to your own cable as much as you like (sighted), then listen to the cheap one as much as you like (sighted), then we do the random switch (unsighted)
- at least 16 trials to be done
- no results communicated to you until all tests done
- no alcohol to be consumed until after the tests are done.
So, PM me if you want to do this. Either as:
- someone to provide their system for the test, or
- as a listener for the listening panel.
Any takers?

Sounds interesting. Recommendations:
- consider PM'ing SY for procotol suggestions
- bring two pair of your cheapies and swap for the subject's cable, that way you're always swapping with a cable 'from the box'
- find a way to mute the speakers during the swap, in my system a pair of 'BudP Lite' interconnects make a very different sound than twisted plastic-insulated silver pair when the RCA ground breaks, presumably because of effects at RF

If the subject can hear any difference in the way you rustle around, even from next door, it's a hint. Swapping cables at every trial also standardizes the connection re-seating, time spent in transition, etc.. Paranoia. 😀
Is that the same as being one-eyed John?😉
Too good a line to pass up and NO OFFENCE intended!
where is curly? he seems strangely quiet.
For sure boconnor.
are we talking interconnects or speaker cables?
If speaker cables, then two pairs of hands better than one?
If there were one person behind the speaker (ie two people each to a speaker), then why can we not have two runs of cable off the amp, only one connected at a time to the speaker?
Am I missing a technical point?
If we could do the above, then I don't see the need for the listener to leave the room...as I said, what am I missing (these things are hard and tedious enough to warrant trying to make it less 'boring' for lack of a better word as possible)
Would be good to do a prelim, where the person can make sure that he hears the differences sighted before moving to the blinded.
We could test to see if the person hears a switch and needed cables thrown in the line too....but be wary of doing too much...you will only get the volunteer once. After he has done it blind he will NEVER do it again.
We only get one stab at it so best to do it as airtight as possible the first time.

only the mean ones? what did the nice ones have to say?
sin binned rather than banned tho?
Must have been a few posts deleted as well, did not notice many bad posts when I went thru last nights installment of the saga. He always felt persecuted too, will feel even more so now I suspect...it would have helped his cause if he'd answered questions tho.
He's banned. They apparently get together as a group and decide these matters. Well, I don't see what he did to get banned. I've followed this thread pretty closely last couple days. I could speculate about what happened, but I won't.
At risk of offending Janneman's sensibilities even further by in his view continuing to perpetrate nonsense I believe it was the WW "box" .
I had understood from a much earlier post that this had been designed to disguise the sonic signature of a familiar known cable so that the listener could no longer recognize it and would be, effectively, listening to two unknown cables. [If I misunderstood this please put it down to strong pain killers for my Achilles tendon problem!]
I also assumed that BOTH channels of this device would sound the same as each other so that there was no inbuilt preference i.e. that the test was - within its limited way - fair. It seemed to me to be a well intended but totally flawed idea!
"All switches are flawed, but some are more flawed than others", to parody George Orwell!🙂
If I am wrong in all of this I probably deserved the sword of Janneman's indignation!😡
[I eventually got around to "H" pattern attenuators built on Shalco switches. But I have a beautiful ex radar two channel attenuator-switch with twin 24 pole twin-rotors which will also get the treatment with properly matched resistors.]
