High tempertature aluminum VC’s?
I find that absolutely amayonnaise.

 

[Cal Weldon]

My thought is that if you’re willing to freely donate your money, then do it to things that need money far more than your sound system, that doesn‘t care so much about the wires you connect it with.

 

[Galu]

Lower mass comes to mind...

I read there is another advantage, which you may be able to confirm.

Aluminum wire requires more cross sectional area to do the same job as copper wire, but this can have an advantage in a voice coil when it comes to the length of the coil windings.

An aluminum coil of the same impedance as copper will end up with a longer winding length, increasing the Xmax number.

 

[kodabmx]

I have no idea about that to be honest.
I figure you would either need a thicker wire of the same length or a shorter wire of the same diameter to match the DCR though.

 

[JMFahey]

I was thinking that #28 or thinner stuff, but yes I could be a high estimate.

#28 AWG is 65 ohm per 1000 ft (305m) so 2 meters amount to 0.43 ohm or 0.9 ohm for a 2 wire cable.

At 7X intrinsic resistance, iron would be 6.3 ohm.

Both ridiculously small values compared to circuit impedance, so even in that extreme case, difference will be INAUDIBLE.

Well, that´s not really an advantage but a handicap, since it forces you to have a larger winding length, like it or not.

The real disadvantage of aluminum is that needing more wire section to compensate for increased resistivity winding thickness increases, so needing wider gaps, so becoming magnetically less efficient.
You waste more of the possible magnet strength.

 

[Galu]

Isn't the need for a wider magnetic gap negated by using flat aluminium wire as shown in my attachment above?

Thought for the day: Why are hyper-expensive interconnects needed for music reproduction when they are not used in the recording process?

Good thinking! But also notice what IS used for recoding. Purpose-specific cables designed for audio from manufacturers like Canare and Mogami that have met safety and quality control standards. Not leftover wire, steel cable or aluminum.

 

[kodabmx]

LOL define "leftover" wire. A spool of 100M with 25M left is "leftover wire" to me.

Lots of the microphone cable we used was aluminum. Mainly the in-wall stuff... It looks, bends, and cuts like it is anyway: https://secure.sayal.com/STORE2/View_SHOP.php?SKU=209192

And remember, most of the components soldered the the circuit boards in the equipment being used have steel leads.

for playback we want the very best parts and equipment so we can extract and hear more from the recording, this regardless if the recording is done with only junk and farts or not

Wel, the very best for audio from engineering standpoint of view is RG59 (coax cable) like used in the most precise testing gear like the absolute toplevel "Audio Precision Audio Analysers' (the APx555). RG59 cable on rolls comes at less than 1$/€ per meter cable. Ad hgh quality connectors (like Neutrik) to it and you got the best that exist from engineering standpoint. But they don't look as fancy as the "audiphile cables" that you like.

 

[kodabmx]

Agreed, but I use rg174 because it's more flexible.

 

[cbdb]

Mine would be less than 0.1%.
I have a lot of gear but not enough cables to hook it all up at once. I probably own fewer than 30 IC's.
If people want to spend their money on wires, that up to them.
Some people like to buy expensive salt and put it on cheap meat.
Some people put saffron on their cottage cheese

Saffron actually makes a difference.

Right because the techs and engineers at recording studios want the worst equipment so they can deliver the worst sound.

Coax is for unbalanced and digital systems. Twisted pair is the standard for balanced systems, which most studios use.

Your music has already been thru a 100' of this I'm sure your 2' of audiophool cable will make a difference.

 

[Cal Weldon]

Yes cbdb, I think you know what I meant.

 

[schiirrn]

If we're trying to be perfectly Fair here oh, our systems were capable of the utmost resolution. They were open Windows to the truth.

Or maybe they were badly engineered with high output impedance ("audiophile" tube preamp with 12AX7, output taken from the anode, too much gain, too much Zout, yet popular) and/or marginally stable and therefore easily upset by minor differences in cable parasitics that wouldn't bug anything less "fancy"?

 

[Flaxxer]

None of it bothers me. I would just own an 80s rack system if I couldn't hear differences, and be intelligent enough to spend my funds on another hobby😉
Easy enough...

Not as much as "negated", just somewhat compensated.

Round wire is very inefficient as far as space occupation, best case is 78% , while flat ribbon (actually rectangular edgewound) occupies almost 95% of available space.

Ah, those backward play messages. Cable price has nothing to do with that.
