Finolex speaker cables

[arj]

Well i might just import some basic but higher qlty. 12 guage cable then from amazon or parts express. Seems to be easier.

Cheers,
Sid

get the Romex from Home depot. Solid core..and very nice. was considering getting a roll for a dedicated cable run from my switchboard to the audio ports.

Cryoed Romex is what I use

 

[keith_correa]

Get Polycab cables instead. Every bit as good/bad as Finolex and easy to find everywhere.

 

[prem]

I agree with Keith. Romex being solid core is a pain to install. I got them some 12 years back but if I were to redo I would use local wire. Polycab is nice. Rest of my house, I use Polycab

Wonder what you guys think of these speaker wires Buy 50ft 14AWG Enhanced Loud Oxygen-Free Copper Speaker Wire Cable Online at Low Prices in India - Amazon.in

 

[Fantastic]

Do you know anyone who has these cables for over a year or two ?
Many transparent cables ( also non transparent types ) do let oxygen diffuse through the plastic and with time the copper corrodes.
A few use very good plastic insulation and seem to resist this. Would the plasticiser also corrode the copper ? Maybe but we don't see much info on that.

Just look at an old cable and if the copper looks tarnished inside then it isn't good for you. If your cable is 'cheap ' this is almost certain !
OFC copper apparently tarnishes less easily . I don't know if this is true.

This looks to be a good cable to try. Litz like construction. Nice!!!

What puts me off is that a Brand X cable which was good a few years back (and is still holding on) does not appear to give the same results if bought new - though the specifications are the same. It is seriously difficult for us to match all specifications though the use remains the same!! Talk about cutting (invisible) corners!!!:lol:

just get this
the klotz 3 core power cable 2.5mm sqaure

TITANEX H07RN-F - rubber-sheated cable - KLOTZ AIS GmbH Onlineshop

http://www.hifimart.com/cables/power-cable/klotz-unterminated-power-cable.html

its not litz "like" construction

it actually IS LITZ construction

Can you confirm that each individual strand is insulated from the other strands in this "LITZ" wire that you recommend? In the wire that I linked to, I could not hence I referred to it's construction as "Litz like".

 

[magma]

nope each individual strand is not insulated
i dont think it can be
if they were to isulate each strand in a 50-60 strand core
and have 3 cores

the god damn power cable would be and inch THICK !!!
and cost the earth

i just saw this
which mentioned litz construction -( in the Advantages section )

Litz wire does not cost the earth. And insulating each strand need not make the cable an inch thick. Nowhere close! Insulating each strand need not necessarily mean that each strand has a coating of pvc/teflon/etc to make it thick - even enamel can insulate (which is typically used for litz insulation) and that coating is not thick at all. I suggest you take a look at real litz wire and then you will know what I mean.

 

[magma]

so
is the website accurate ? or inaccurate ?

I cannot say for sure unless I KNOW that the wire in question has [not] individually strands - I asked you to confirm, remember?

I do know this though - I have seen many wires called and advertised as Litz just because they are constructed in the Litz pattern BUT they do not conform to the "individually insulated" principle of Litz wire. But there are exceptions like the Polycab wire whose photo I linked to - the winding is in the Litz pattern but they do not claim to be Litz. Similarly MX and Chetan cable has speaker wire constructed like Litz but they do not claim to be Litz.

Edit: Anyways, let's forget about whether these individual cables are Litz or not - I just wanted to make a point about Litz which I think I have made.

 

[magma]

yeah but i think these guys actually have mentioned the standard to which they conform to as well

ill drop them a mail

lets see what their answer is

i have the cable in question btw
its highly shiny ( unlike a raw copper strand )
so i dont know whether that shine/gloss is actually a micron coat as you are talking about

and when i scrape it with a blade it gets all dull

its pretty darn soft/flexible though

 

[keith_correa]

I checked the standard that they claim before my first response to you hyeah:

The standard has nothing to do with Litz. I doubt that there is a "standard" for Litz.

Good! Let's sort this out once and for all wrt that particular wire. Ask them if the strands are individually insulated - and what the insulation is.

Touch a clean soldering iron to the strands and see if there is a burnt residue on the iron.

How does one scrape off the insulation on individual strands of a multistrand cable (assuming each strand is individually insulated)? Some chemical to dissolve the insulation? Or plain old elbow grease?

More often than not, soldering iron heat is enough to melt the insulation which is enamel [in most cases]. Some say nail polish remover works well to remove the enamel and some use a solder pot.

(Flame suit on) I may be wrong but using litz wire in power cord will not have any advantage. Or for that matter speaker wire. Litz formation is to avoid very high frequencies getting attenuated. Using solid core (Like Prem have used) and appropriate gauge will be advantageous as it will attenuate high frequencies noise (subjective view) and can supply ample current when required. Personally I have found solid core speaker wire takes away little bit of harshness in upper range.

From Wikipedia:

Another way to explain the benefit of Litz braiding is as follows: the magnetic fields generated by current flowing in the strands are in directions such that they have a reduced tendency to generate an opposing electromagnetic field in the other strands. Thereby, for the wire as a whole, the skin effect and associated power losses when used in high-frequency applications are reduced. The ratio of distributed inductance to distributed resistance is increased, relative to a solid conductor, resulting in a higher Q factor at these frequencies.
