Blind test your speaker cables vs...

[Joe Smith]

This again?

Nop test, blind test. Buy a 50 m , 164 ft lamp cord , thin installation cable in that case. Sooner or later you will hear a difference. The only question is when? That's what I'm interested in.

...100 m..150 m..(ok then maybe it will be a bit too much money for a small blind test, should be added).

Worked for Monster in their phony demos once upon a time, took quite a length of the thinner stuff, tho....

You just buy nice thick ones (low resistance) and forget. No need for blind tests.

Speaker cables I already have:

OFC or CCA speaker cable?

Same price OFC (Oxygen Free Copper) 2.5 mm2 VS CCA (Copper Clad Aluminum) 4 mm2. Length about 3 meters / 9ft between speaker - amplifier. Not a subwoffer. Does it matter which one I choose? Good price on the cables. 10 meter / 32ft for $18.:)

BUT if I don't hear a difference I could use a pair of thin cables instead as it will make it easier to squeeze them behind the moldings in my living room, listening room.

There is a lot of unnecessary testing that we already know the results of. BUT it can have another huge advantage instead, for example:

PS Audio Ultimate Outlet Review

This is a review and detailed measurements of the PS Audio Ultimate AC Outlet. It is on kind loan from a member and cost US $299 when available in 2002: The device is is the typical noise/surge filter targeting audiophile market. Not much to the front or the back: I can't see any safety...

The advantage of the test Amir did is to point out electrical safety. There is of course an abysmal difference between possibly, probably not at all, hearing any difference in speaker cables VS a gadget that has the potential to burn the house to the ground.Or even worse cause someone's death.
Amir regarding PS Audio Ultimate Outlet:

"Conclusions
Dangerous! Avoid at all cost!!! Please, if you have one, put it aside or better yet, send it to be recycled/destroyed. Do not sell it to anyone. I am glad it is not on the market anymore or I would really lose my cool! And oh, even if it worked, just like a number of audio power tweaks I have tested, it does nothing for your audio equipment.

Needless to say, I cannot in any form or fashion recommend PS Audio Ultimate Outlet. Let's hope the company knows more about safe AC design now than it did then."
