Purist audio designs speaker cable

[Johnny B Good]

Today i received my new speaker cables, purist audio designs bi wire.

beautifully made speaker cable and considering the thickness, its not as stiff as i thought it may have been. Very easy to bend.

However, i do need to ask, why would they mark them left and right?

per cable or each cable as in + and -

Very nice looking cables for sure.

I just googled your question and within one review result for their products, I found this paragraph that confuses the question even more, as if you need to be aware that they are left and right

"The cable ends were terminated to my order with gold-plated spades on both the amplifier and speaker ends. Directionality was clearly marked via a large label on each cable, but right and left cables were distinguished only by the border color of these labels. This is not a problem, just something to be aware of. Did I mention that these cables are heavy?"

From their own site, they feel the need to post a chart telling you that R= Right and L=Left

In my HT setup my amps are in a different room than my speakers. Whenever I disconnect for cleaning or moving, whatever,etc. it is helpful to have the cables marked so you know.

If the cables are the same and same length, why would it matter if they got swapped?

I have speakers that due to their design should be setup as left and right, but it should not matter with 2 runs of identical Speaker cables.

If you lay the cables out side-by-side, are the red (+) and black (-) termination "sides" identical? E.g., + and - for Left channel :then: + and - for Right channel OR ARE THEY + and - for Left channel :then: - and + for Right channel?

For my customers, if they tell me up front what amplifier and loudspeakers they are intending to use, I will usually do my best to lay out the cable terminations (at least on the amplifier end) such that the cables will dress nicely with spades with the + and - for each channel to match the binding posts on the amplifier. Whereas most loudspeakers have the + and - binding posts in the same orientation on the rear of the cabinets (looking at the rear of the speaker, the binding posts will be - on the left with + on the right side many times) but on amplifiers, looking at the rear the binding posts might be + and - on the left side of the chassis while the right side has them laid out - and + --or-- they might be + on top left, - on bottom left with + on top right and - on bottom right. It all depends on the amp design and component layout.

Did you communicate your gear types when ordering the cables? If not, then it may be just a convenience thing as Elescher has pointed out, that it allows you to connect left and right channels properly if your gear and loudspeakers are in different locations.

That's a great explanation Mike and it would have been good if the MFG site spelled that out a little but it looks like you answered the OPs question perfectly.

just went to have a look, on the amp side they are both the same, but on the speaker side with the biwire runs, they are opposite to each other.
I didnt request it, nor did i tell them what equipment i had, its the norm with purist audio designs to just mark them as left and right

Then they did well and you have your answer. Great.

 

[Johnny B Good]

i do indeed, cheers Mike

Yes, it seems to me it's just practical -- even in the same room, you find yourself with four wires coming to the back of your amplifier and you have to play follow the wire to know which is left and which is right. I always mark wires diffferently, though I don't specifically mention right left or right (use colored tape).

I don't think anyone assumes that there should be a physical difference between right and left per se -- assuming indeed they are the same length. And I know of no manufacturer who actually offer to compensate for length if you cables are different length, though an Exakt type system with digital phase control would allow that.
