It's not mumbo-jumbo, it's been used for decades to find faults in cables and for microwave (ultra-high-frequency) work.

Eyeteeth- Keep in mind that the marketing departments of many cable companies take, uh, liberties with the technical information that the engineering department feeds them. Sometimes there isn't even an engineering department...

I am not at liberty to comment on the specific claims of other cable manufacturers thanks to the Head-Fi rules (they're competitors), but I will say that I find cable ads are usually good for a laugh... Really, if you're buying cables, read the reviews of how they sound, not the "technical information." The former is what we're all after, right?

My TDR stuff isn't exempt from this rule, either. It's incredibly useful for quick & dirty tests, or checking cables for problems during production, but in the end my ears are *always* the final determinant. It's really amazing when you think about it -- the way we can hear changes in a cable that are first visible on a test instrument at frequencies a million times higher than we're supposed to be able to hear. I suppose high-end audio is something like a "special case" of electrical engineering, just like quantum mechanics is a "special case" of physics

Not me, I just want a cool looking jump rope that hopefully sounds good when I plug it in and is VERY expensive.



If you did not catch my sarcasm, then >>>

Hey, this thread is entitled "the Truth, the whole Truth, and nothing but the Truth..."

There are several very good reasons why our ears will always be better at listening to gear than test equipment. The biggest being that, well, we're evaluating gear on how good it sounds to our ears, not our test equipment

Let me introduce you to my UltraReference line of products...

Seriously, though, since I'm spilling a whole bunch of 'dirty little cablemaker's secrets' here... Would you guys prefer to buy cables that are surrounded by mystique and arcane technical jargon? Audio is after all highly subjective, and I can imagine that the theatrics of ad copy could enhance the customer's experience in the same way that a good screenwriter's script enhances the audience's enjoyment (and suspension of disbelief) when they watch a film.

Im poking fun at myself.

eric343 is much more knowledgable than I am & I don't mind admiting it.
