hi,
im looking to separate my equipment from my amps and speakers, but my only option is gonna take 15ft of interconnect to get to where i need to place the amps. is there any cable that is maybe better to run long distances like that. i was looking at shunyata ztron pythons which would cost about $3k to do this. yikes!!! or acoustic zen wow, which are inexpensive 5m would be around $1000 and kinda match my zen silver ref2's.
is there a good way to do this or do i just have to bite the bullet and spend the money to get the cable i want in the length i want.
i wanted to switch all the cables over to shunyata, because of the rave reviews they get around here, but $3k for the cable that can do this is not something i ever wanted to spend on a single interconnect. id buy an awesome cartridge for that.lol.
is there a good quality pair of diy cables i can get for this??

I would bite the bullet and get the cables you want. It cost me a few bucks to get ~22ft of Transparent Reference Balanced cables to connect to my amps that sit between my speakers. I know it was worth if for me and I am considering upgrading those at some point.

i think you may be right. i just hate using that money for something like that, when i know there are 5 cartridges i want, that are less than that.lmao!!

sorry mike no wire world for me. nothing to do with quality, or the "other dealer" its a personal thing i have with the company itself.
long story.lol.

Does his gears compatible with XLR ?

nope, my stuff is rca all the way. dont know why but in the past i had gears that used xlr and rca and i had both cables, and i always preferred the rca. so when setting up my system this time i bought what i wanted and never worried about that. turns out i dont have an xlr jack anywhere. although the snappers had xlr's and i always wanted to test them.

Steve, I wasn't suggesting you go with Transparent. There are many fine cables out there and I am sure you will be happy with Shunyata.
 
Steve . I want you to consider the "MOGAMI" cables. Get them and terminate with your choice of RCA adapters.

MOGAMI 2549 is made of Famous MOGAMI NEGLEX Technology Oxygen Free Copper. Terminated with improved version REBEL RCA Plug, thicker gold plated & professional outlook! Highly recommended for high end audio system!

Furutech FA-220 off the roll. Furutech Flux XLR terminations. TechFlex Flexo Conductive carbon polymer filament braid if you want an EM dead cable.

Great balanced solution for those longer runs. Eg. HT.
 
Steve,

Be careful. If you run rca's longer than say 2M you run the risk of losing both high frequency and low frequency (mostly high) information. I used to do it all the time until I realized that there is definitely a loss of information when running long single ended cables. If you are running long runs balanced is the only way to go. If you have to run rca's then just bite the bullet and keep all the runs short, (under 2M), even if you have to keep all of your gear between the speakers.

Good advice, as is the general consensus.

I have personally succumed to not using either long rca's or long speaker cables. There are exceptions, like Nordost Odin sounds great at 4M lengths???,not sure why, but it does. But in general, other than balanced Ic's or digital cables in dig systems, I move whatever I have to move (furniture and equipment) to use short rca's (because I like single ended vs. balanced, always have) and something less than 3M normally although I do use 4M sp. cables with my Ansuz sp. cables and they sound great. My experience lately has been the shorter (not too short) the better if you want to preserve signal as well as reduce noise induction into the signal.

Regardless of what I or anyone else might say, the real answer is that you never really know until you try it. There are generalities but like they say "ya never no".

My personal experience was that I have been using 25' long rca ic's for several years as I always had all of my electronics off to the side so that they would not be in middle of the speakers, which can affect the soundstaging. I always had a feeling that the long rca ic's were not the best thing sonically, although all my cables that I used like this were very "expensive" cables so I thought that this was helping the situation.

Then Lars visited me a while back.

Lars said that those long rca ic's were killing the top end. I always attributed the lack of a sparkling, extended top end was due to my very absorptive room. One day a month or two after Lars left, I said let me do a test. I moved my cdp and pre from the side wall in between my speakers and close the mono amps, which allowed me to use 1M and 2M type rca ic's.

I was stunned. It was like I turned the tweeters "ON". Not on one set of speakers but on five or six different speakers, each acting the exact same way. I would never ever run long rca's in my space again. I actually have sent all of my long rca cables off to be change over to balanced or cut down into shorter length cables.

This was my personal experience.....nothing less and nothing more.
 
Some people say that 2 or/and 3 meter HDMI cables are preferable over .5 and 1 and 1.5m ones.

What about some of them AC power chords?

...People with large home theater rooms and 100 feet of speaker cables?
...Long subwoofer's interconnects?

Can you hear a sound difference between a cable that is one foot longer or shorter than another one of the exact same model brand?
 
Hello Steve - Petro85

You will get a lot of differing advice about what to do. i suggest you go to our website and watch the ZYTron Video in the technical section. It shows the response of a Python interconnect with a 10Khz squarewave. The test cable in the video is a 30 meter cable! As you can see there is a clear loss of high frequency information without the ZYTron circuit but there is a dramatic difference with it engaged.

In our factory reference room we use a 15 foot cable between the preamp and amplifier. In my home system, there is a 20 foot RCA between the pre and the amps. Audio Resesearch uses one of our Anaconda interconnects in their reference room between the preamp and amplifiers that is 30 feet long. In listening tests we cannot reliably tell any difference between a 1 meter cable and a 15 foot cable.

The acoustic benefits of removing racks and reflective audio components between the speakers far outweighs any theoretical loss in a long cable. In my opinion, a 15 foot cable is not a particular problem. JMO and YOMV

Just FYI...Long speaker cables are MUCH better than long interconnects. The signal loss over a 10 or 12 gauge speaker cable is measured in dozens of yards

On the interconnects, you can go with the Blue Jeans cable in that length for about $75 a pair with no loss

The Cable: Blue Jeans Cable LC-1 Low Capacitance Audio Cable

The most important attributes of a line-level unbalanced audio cable are (1) shielding, and (2) capacitance. Heavy shielding protects audio signals from interference from outside sources. LC-1 Audio Cable uses a heavy double-braid shield, with one bare copper braid laid directly over another for extreme high coverage and high conductivity to ground; this is the identical shield configuration to Canare LV-77S, which tested best in our review of audio cable hum rejection characteristics (LC-1 hadn't been designed yet so wasn't tested at that time). By shrinking the center conductor to 25 AWG and foaming the polyethylene dielectric, we were able to get capacitance down to an extremely low 12.2 pF/ft, much better than LV-77S at 21 pF/ft. Capacitance can be important, particularly in long cable runs, because it contributes to rolloff of higher frequencies. The softer dielectric material and smaller center conductor, meanwhile, make the cable highly flexible and easy to route. LC-1 is built exclusively for Blue Jeans Cable by Belden, the leader in American communications cable, and is rated CM for in-wall installation in residential and commercial environments. For more information and specs on LC-1, read our "LC-1 Design Notes" article

No..some of this is subliminal. It has to do with capacitance and shielding. Ask an electrical engineer about power loss over distance...you are talking hundreds and hundreds of feet. Now that doesn't address noise but that is handled via shielding and proper grounding.

The reason it is so important in phono cables is because capacitance affects the cart signature and load. Its not the same for line level non-phono components.

Another myth, speaker cables should be the same length. Visually, yes, Signal. No. You could have 1 10ft long and the other 100ft long and the signal response would be fine. We are dealing with the speed of light (or damn close here) with loss that would have to be measured in miles.

a specific individual electron travels at what is called the "drift velocity". The drift velocity is very very small.

v_drft = J/(ne)

where J is the current density in the wire: amps/meter^2
n is the density of electrons: electrons/meter^2
e is the charge of the electron: 1.6X10^-19 Coulombs

suppose the current in the wire is 1 amp and the cross-sectional area is 1 mm^2

assuming the wire is copper, the number of electrons is given by:

n = (1e/atom)(6.022X10^23 atoms/mole)(8.96 g/cm^3)*(1 mole/63.5 g)

n = 8.5X10^22 electrons/cm^3

so we find:

J = 1A/10^-6 m^2 = 10^6 A/m^2

v_drft = (10^6 A/m^2)/[8.5X10^28 electrons/m^3)(1.6X10^-19C)]

v_drft = 0.0735X10^-3 m/s

so we see that electrons crawl through the wires at a snails pace.

the wave of information is the thing that travels at c (the speed of light) not the particle. imagine a row of dominos. topple the first one and then they all begin to fall, you can watch the information wave travel across the dominos but the individual dominos have not moved much from their original position.

electrical current travels along, not through, a copper wire
