Is mains wire seriously a competitor for my Russ Andrews teflon coated weaved anti emi speaker wire?!?
I don't know, try it and see.

I'm using some basic Maplin 42 strand stuff - the thicker 79 strand cable sounds no different to me (I'm running 2.5M lengths).

Oh, and my speakers are 4 ohm too, so that would make them more current hungry.

I've also tried various other cables, none of which seemed to be of any benefit.

minimum spec mains lead.


optical interconnect.


anything less and your not doing your system justice.

Yeah looks good cable, but boy would it be hard getting it into the banana plugs. Plus a seriously hot soldering iron too.

they use a laser solderer that focuses the beam through crystallised angels tears.

Ah, but that just clips into a standard plug top that plugs into your wall. Gonna need plug pins of pure unobtanium forged in dragons breath.

Besides, think my amp is on a 3 or 5 amp so no good for me. And a new all socket. And new house wiring. And new breakers. And new sub station....

have to disagree - its been done with cables - no measurable difference but there was clearly an audible difference. I'll see if I can try to find the test)

Gold plated titanium diamond encrusted fuses, with hand spun fuse wire and 100% pure copper plated bullst. I heard that the better option is to replace fuse with circuit breakers. Nurse, the screens

Yeah but you have to check that the run with the lay lines or you get ghosting. Real ghosting..... wooooooo

I suppoase the difference is in 'measurable'. If you want to take it down the the physics level then every element is different silver, gold, copper etc. Without actually finding the test I would assume they meant measuring their electrical properties.

maybe the difference its down to quantum mechanics

No measurable difference between cables suggests pretty rudimentary measuring equipment; there will be a measurable difference if there is an audible difference. There can be significant audible differences between components that 'nominally' measure the same; here are a couple of articles about capacitor performance for example.

I went into our new local (town in SW France) 'crack converters' shop the other day and came out with a pair of mint Mission 760i bookshelf speakers. Took 'em home, put 'em on the mantelpiece, hooked 'em up with a bit of spare 5 amp twin, carefully ignoring the opportunity for bi-wiring, and found they sound an absolute treat - to my ageing ears. Price: €6.99 with a 3-month guarantee.
Result!

Just a little story for you about how even simple components are not perfect and can create strange effects.

I'm working on a problem this morning where jitter is occasionally excessive. This lowers the performance of our audio resamplers.

It turns out that the variable airflow over some vcxo control capacitors is causing this jitter, easily measurable on the right kit. As the capacitor temperature changes, its output voltage is changing, affecting a clock frequency and hence the jitter. (Jitter is very important in getting good audio performance)

The fix is to put silicon goop over the caps. Works fine now, very stable.

My point is that even small airflow changes inside a box can affect key signals due to the fact that capacitors can be very temperature sensitive.

Could you hear that?

You do know the solution is not silicon gloop it's a properly compensated oscillator, i.e TCXO, MCXO or OCXO don't you?

No chance of hearing it, the subsequent stages can deal with the jitter, it just didn't meet the standard.

The gloop is for the sensitive input capacitors rather than the VCXO. I don't think the budget would be there for better VCXOs, we use four at £10 each at the moment, quite a large part of the board cost.

Yeah, yeah right.

You put some snake oil on something and it made a difference? Where's your ABX blind testing? Without that it doesn't exist. Even if you measure it.

I wire my speakers up with unbent coat hangers twisted together and the guy from the local hi-fi shop didn't even know the difference!

Yeah, right, coat hangers arent insulated, so do you get many amps blowing from being shorted out?
