SPEED: 98% speed of light
or for a bit less £££
PROPAGATION DELAY: 96% speed of light
or for even less ££
PROPAGATION DELAY: 90% speed of light
Now what has the speed of the electrical signal got to do with anything audio?
Without doing the sums, I would expect the length of cable to make a bigger difference in the time the signal takes to travel than a few odd percent
in its speed.
And how does this related ot audio signals, audio being many many orders of magniture slower than c?
but this is irrelevant as the electrical signal will be phase shifted accroding to the L-C of the circuit and by different amounts
depending on the signals's frequence, which is equivlanet to the speed being different for differnt frequencies.
Seems like irrelevant marketing BS to make punters part with their money. (and we are talking non locost amounts )
Or am I missing something obvious here?
Moving your head 0.001mm will make more than twice the difference to the time taken for the sound to reach you than the difference between the
electricity travelling at 100% vs 90% of the speed of light along a 3m cable.
Don't get me started on the level of idiocy of high-end hi-fi!

Better get some calibrated wire cutters to ensure the cables are exactly the same length, wouldn't want one speaker to be a few femto seconds
earlier in it's sound production would you. That would sound awful to the 'trained' ear. If you're spending the money of 98%
speed of light cables it would be a waste not to get them installed correctly.
memo to self must rebadge some £10 cutters put a gold flash coat onto the blades and package them up with a cheap laser measurer. I'm sure I
could get a couple of people to buy them for £500 a set with a bit of work on the above pitch.
Must buy some new clothes for the emperor while I'm at it.

^^^ excellent - I love all that stuff!!
8 grand for a pair of valve monblocks is relatively cheap - these can go to 50 or more.
I've played with various interconnects and speaker cables but mostly not been able to hear the difference.
Recently picked up a pair of quite £££ speaker cables of the bay - bid but didn't expect to win and have listened to them last night, and I am
trying to convince myself they don't sound better becasue I know they are more £££. There is a difference but hard to put my finger on it.
One cheapish but worthwhile mod was to use 2 maplin mains conditioners - one noticeable affect was the mechanical buzz from the transformers in the
amps is not as loud plus the bass was improved. One could argue this is due to a smoother mains waveform but stuff like directional speaker cable?
Years ago when I was interested in high end audio gear, I read a very enlightening article about speaker cables.
The author was a correspondent for a Danish audiophile magazine.
After trying all kinds of rediculously expensive cables, he had gone rushing round to his mates to tell him that he had just found the cable to end
all speaker cables.
He had been given some to trial.
It had amazing clarity, generated no noise whatsoever and wasn't as expensive as he had expected.
What was this wonderous product? You may well ask.
It was 2.5 twin and earth mains cable!
Go figure
In the Frey info it states: Mono-filament design reduces insulation contact with the conductors by more than 80% which means that current signals
traveling above the surface of the conductor are virtually unimpeded by the insulation material.
WTF?

LOL!! That was my favourite bit too! I'm picturing electrons leaping out of the surface of the metal and diving back in in graceful arcs, like dolphins playing in the sea . Funny though - I don't remember touching on current flowing outside conductors much in my electrical engineering degree (well not at audio frequencies anyway)!

DC Power flow in a concentric cable
Application of Poynting's Theorem to a concentric cable carrying DC current leads to the correct power transfer equation P = VI, where V is the potential difference between the cable and ground, I is the current carried by the cable. This power flows through the surrounding dielectric, and not through the cable itself.
considering garbage music played these days the best thing they can sell is a pair of effective earplugs
rather listen to the live sound track of a V8 or V10 than most of the music these days

hmm, we did touch on this, something to do with Poynting's vector - from what I recall, the electric field flows outside of the conductor and the points from and where it flows to are defined by the wire ends. Weird stuff.
Here is a snip from wiki-p.
