The fact is, you have no clue what you are doing.

Now that we have established that you have only heard this supposed phenomenon and then invented some crackpot theory using words you do not understand, we can all move on.

This could be easily measured, if it were true.

Yes Dan, sometimes the only way we can tell things apart is by LISTENING. Cable directionality seems to be one of these characteristics.

Like the brightness of silver wires John? BTW, T very politely asked you a question about that, do you have a reply you feel you can share?

I'm confused. This is an audio forum, right? Isn't audio about listening? Or is it about reading numbers on a display?

Here, it's about reading what people say (or not)

Yes, and this is one feature of the TS/GC loopback cable used. Goop makes directional effects of standard cables more obvious, and also makes more obvious that the TS/GC cable is indeed essentially non directional. Fold in half and cut is how I 'discovered' directional effect in coax/shielded cable hardwired to my TT....this led me on a merry chase until I was shown the effect as I described in a previous post.

Yes, try listening to some silver cable and you may 'discover' something for yourself.
I now have loopback recordings that illustrate this 'brightness', who cares what 'theory' says when the facts are clear.

Sorry Dan, wrong assertion. The interconnects may be accepted as normal, but there is at least something wrong with them, most probably due to the crappy RCA connectors, try BNC or better direct soldering.

Perhaps not so easy for you and I, but I'm quite confident that Pavel can.

You have no real clue about audio or the results that I am achieving. So a couple of files were bunky but not fatally, so what ?. You have not indicated that you have auditioned any of the other loopback recordings, suggest a track you know and like and I will process it for you. My next round of loopback recordings should capture directional effects and stand as proofs. Then we can debate the causes, in the meantime you could try reversing one interconnect and try the experiment for yourself, that is if you have a stereo worth listening to (IIRC you have a little Bose satellite system, is that right ?).

Dan.
