Correct Gauge for 6 in jumper/interconnects?

Hey everyone,
I am making some jumpers for my amp/preamp and was wondering which gauge wire i should use. i am hoping that i will be able to use silver, but sometimes the silver is just too expensive for a thicker gauge. i have found 24 awg silver cable at qables.com(http://www.qables.com/shop/index.php?main_page=product_info&products_id=503)for about 8 dollars per meter, and would buy it but i need to know whether it is too thin or not. if not, i might as well purchase it because it is the cheapest i have found. thanks everyone!

Is this pre or post amplification? 24 is probably fine for pre-amplification, but you might want a little bigger post amplification. If I were you I would just find some generic hook up wire for something like 10-20 cents/foot and use that. No need to spend a fortune on wire.

40ga signal

20ga ground

 

Seriously.

 

If you are concerned with durability, 33ga signal/20ga ground.

pre. goes from pre amp to power amp.

do i really need a 20 awg ground if i am already doing 24 awg in the first place? How about 24 awg signal and 24 awg ground? im just trying to consolidate where i buy my wire from and qables is the cheapest for silver but they only have one gauge available.
thanks

i just ordered a meter of 24 awg silver from qables for a total of about $13 including shipping shipped to chicago area and have also ordered 4 straight rca plugs from switchcraft(gold plated, two nickel handles and two black handles)for about 2 bucks each.
thanks to the both of you!

I use common copper magnet wire. 

 

The idea behind a thick & thin interconnect is that it helps to limit ground loops by having a higher impedance signal path than ground. 

 

For practical applications, you will never find wire thin enough that it attenuates bass when used as an interconnect. Try one out as a second or third project :)

 

Ooh, yea, 2x24ga is OK, but I think thinner is better.

thanks. can you explain how a magnet wire works/what it is? i have heard of them, but they kind of confuse me.
