Cable advice

Recommended Posts

Speaker wire?  Paul Klipsch used lamp cord.  If you don't want to use that, any 12 to 18 AWG wire that's 100% OFC. 

 

RCA interconnect?  Get something shielded.

Nice looking 2A3 amp.  I've been working with SE 2A3 amps powering efficient speakers for the last 13 years, and with wire for audio for the last 41 years.  

 

My best conservative no-risk advice in 2019  is to use three parallel runs of Mil Spec cable, specifically, M22759/11, for each amp-speaker polarity.   Two of the three should be 12 AWG, and the third 14 AWG. 

 

Minimum lengths should be precisely 9.52 feet, which is 57.125 inches times two.  If you need longer cables than that, go to some multiple of 57.125 inches, usually times three ( 14.28 feet ) will do.

 

Keep the descriptive lettering, on the wire's outside, going in the same direction, for all three wires in any trio.  Connect them, descriptive lettering - amp to speaker, uniformly also.

 

Terminate both ends into spade lugs sold by Michael Percy, budget priced gold plated and, I believe, capable of accepting 8 AWG wire.   

 

Use a Weller D-650 or D-550 -  300 Watt or 325 Watt soldering gun, to solder the spades and wire.

 

Do not allow the two wire polarities to touch each other, on its way from the amplifier to the speaker terminals, nor touch the floor's carpeting, etc.

 

This above, will insure the best possible linear and wide-band transfer efficiency,  2A3 amps to speakers, on a cost versus performance basis.   Look up what M22759/11 wire is !!  It  is multi-stranded copper , with each copper strand silver plated, in a teflon outer jacket.   The silver content is important !  Readily available, surplus and Steve at Apex Jr, on line, is a trouble-free great source.

 

If you have any additional questions, feel free to ask.   Happy Listening.  " An inch of bad wire can ruin the musical experience ".   Its wonderful that you inquire - on how to do it optimally.  Nothing is perfect, but this is easily the best "I" am aware of in 2019, and what I use.

Lamp cord was being used when cars came with 78 series tires.  Nowadays, cars come with 50 or 60 series tires and they handle better.  People have also learned about speaker cables, and I'd recommend at least 14 gauge, with 12 gauge preferred, which will sound better.  This is better than the smaller 16-18 gauge lamp cord, which tends to weaken the dynamics of the music.  12 or 14 gauge speaker cable will allow the speakers to communicate better with the amplifier, and will minimize the reduction in the amp's damping factor.  Twisted pair configuration is helpful, but not essential.  Speaker cables can't improve the sound of speakers, but we can try to minimize how much they cut into the speakers' performance.

 

This 12 gauge cable by Knukonceptz is inexpensive, easy to work with, and will not corrode and turn green over time, due to the individual strands all being tinned.  It's in a twisted pair configuration, which rejects interference.  The SS in the description refers to the colours, Smoke and Silver.

The smaller 14 gauge cable is nearly as good, and costs a little less:

Lamp cord laying on the floor is fine.  Just keep it away from the AC power cables and all will be well.

Wow! 

 

I've used a few different speaker wires.  Currently running 11 ga equivalent braided Cat 5e across the front 3.  Not worth the trouble, but braided computer cable measures nearly perfect. 

 

Roger Russel of McIntosh has a web site that addresses speaker cable, among other things.  McIntosh makes amps and speakers, once.  Look up his site and follow his recommendations.  I would go up one wire size for a little overkill.

I run my 12g zip cord supported by concrete floor stands from my amps to the Super MWM's or whatever is playing on any given day. I try not to allow them to loop over each other to much and have resisted the almost irresistable urge to cook them with an Audiogon Cable Cooker. I also find embedded floor grunge on the zip cord insulation reduces the propensity for magnetic field generation  and have proven to my satisfaction dirty zip cord produces better audio. I prefer to use my TIG torch for soldering and believe if a little solder is good more is better.

 

  On a serious note here I find cables to be fraught with all kinds of snake oil. Simple zip cord works fine for the engineer types I know and does so without severe money loss. I buy 12g Monoprice zip cord made for speakers by the 100' roll when on sale and eliminate any potential for to small a conductor over runs of up to 30'.

Companies just lose me when they put things like this in their copy...

 

Notes – The black polarity stripe is also on the same side of the cable as the printed text. For the Kord speaker wire, this should be used as the negative connection.

 

It's in a side by side configuration... wtf...

 

Their prices aren't bad, though.

Yes, but has copper changed since cars came with 78 series tires?  Copper is copper.  It's been around for a little longer than you and I.

I suggest a double run of Audio Note Lexus. It is great sounding copper litz speaker cable. A bit pricey and worth it. Just like putting quality wheels and tires on your ride.

No.  Not at all like wheels and tires.  Speaker wire has no air pressure, don't spin and have NONE of the components a wheel and tire set have.  You made a nonsense statement right out of Jabberwocky!

Amen.

 

By far the biggest contributor to whatever negative effects cables have is not the wire itself, but the connections at the ends of the wire. A poor connection has nonlinear resistance and, in some cases, even a little bit of diode effect.

@Edgar agree 100% would be curious what folks are using for termination? Specifically for banana plugs  and spades.

Everything what said above.

😁

I have been using as pure coper wire as I could find in my 2-way listening rig.

To this point, I have Knukonzeptz thicker wire as I could get. And they run fine.

On my other system I run VanDenHull cheepest cabel I could buy locally. It is just fine.

If I could advice anything beside that, it would be to experiment with your speakers placement and soundproofing of your listening room.

Those things might surprise you more tha speaker wires. 

Just my  2 cents.

You can order both speaker wire and RCA ICs from Blue Jeans Cable.  You can specify whatever connectors you prefer,.  Well made, decent prices.  Personally, I would order only slightly longer than immediately needed.  I try to keep my cable runs as short as possible.
