Help me build speaker cables please!


Howdy!
I’m looking for input on some home brewed speaker cables. I’m currently using cables I made from braiding 8 lengths of CAT 5 plenum cable together. They’re terminated in silver plated BFA bananas and set up as a biwire configuration at the speaker end. I love their sound, but think I’m ready to try something made from higher grade metal. I’ve been doing a lot with silver in my system and have loved the change in sound almost every time I’ve gone from Cu to Ag. The only place I like Cu better is in the PCs for my amps. That said, I’m leaning heavily towards making a set of solid silver speaker cables, using .999 silver wire from Rio grande. I’ll insulated them with teflon spaghetti tubing and possibly terminate them with silver plated BFAs.

Where I’d love some input is here: do I do one run of 10awg, or biwire 12awg to the woofers, 14awg to the tweeters and mids? I’m using a dared tube preamp and monoblock Ghent audio class D amps (500w into 4 ohm) which drive floor standing RBH 1266 SE/R speakers. They are 4 ohm and have side firing 12" speakers. They like a lot of juice and sound their best when given what they want, hence my desire for large diameter cables.

Cost wise, it’s only $50 more expensive to biwire. I liked the change in sound when I first biwired, but I also went from blue jeans twisted pair 12 awg to my braided CAT 5, which has a combined 9 awg. So I’m not sure if it was the biwiring or all the other differences that improved the sound.

Also, any other ideas for superb sounding DIY SCs are welcome.

Danke!

Todd:                                                                                                                      Actually I am only using the same exact Odyssey Khartago extreme amplifier that Johnathan Vallin wrote about a few years ago.  Supposidly it is the same ampliier that Alan Wolfe of Magico personally used to evaluate his speakers.  Although it is rated at 110 watts, I am using an Audio Research tube LS27 line stage preamplifier at high gain.  On my Martin/Logans they work great.  Still it is the next upgrade I would make if I had the money.  In my personal opinion, a true high quality tube amplifier is the way to go, but it is not practical for my situation.  Anyway, with my speaker wire combination. there should be no problems at all.  Actually right now, depending on the audio source being used as well as the type of music being played, a readout on my LS27 of only 10 to 12 is usually sufficient.  That is very low, although again, that is on it's high gain setting.  One would not believe how "big" a 110 watt per channel amplifier can perform.
Todd:                                                                                                                         I must add that my speaker "solution" is of true refrence quality.  I am not kidding.  It is mainly the MG Audio Design wires themself, but the numerous Jenna Lab's 18 gage hook up wires make possible the essance of the MG Audio Design wires audio reproduction itself.  And, considering what I get out of this wire arrangement, I truly believe that they justify their cost.  Overall if one simply considers attempting to come anywhere close to the performance of say the Speaker wires that say Michael Fremer himself uses and their cost, and my own speaker wire "solution"', and consider the cost difference-well then you would understand where I am coming from.
Todd - Without getting into the design specifics of your amps,,,

From the web...
Can I get a shock from the speaker connections on my Amp?

YES! Amplifiers in the 400 plus watt per channel range are not uncommon today. 

Such an amplifier will put out about 50 to 60 volts RMS to a speaker.

So in very "general" terms, suppose you amps output voltage is 50 volts
- To deliver 500 watts output would require 10 amps. 

In order to keep it simple - and in very general terms...
 
- the current carrying capacity of a conductor is specific to the gauge of the conductor. 

 see http://www.powerstream.com/Wire_Size.htm

18 gauge conductors can handle 16 amps contiuous for chassis applications

Power transmission limits of 2.3 amps are for much longer runs  than those employed for a speaker cable

So the 10 amp rating previously quoted seems about right

Also remember - THIS IS CONTINUOUS POWER !!!

The amp will not come close to the 10 amp continuous at the loudest of levels.

But - if it makes you feel more comfortable use 12 gauge

Steve - I understand. I’m aware that 18 awg is plenty to handle the current of most amps.. but from past experience, fat cables sound better in my system to me.

However! That may be because of the fatness of the neutral.. I’m willing to keep an open mind, but I tend to keep operating based on what has worked in the past until I’m satisfied that the new way of thinking is legit. I’ve no reason to doubt you, my mind just works that way.

Alan - I find your solution very interesting, in that just a 1’ piece of wire could make that much of a difference. And I’m happy you’ve found something that works for you and is unique. I definitely don’t judge you or think poorly of you for spending what you have on cables. I just don’t have that kind of budget right now. Thanks for the input though.. I keep hearing great things about Jenna..
I have tried Silver Cables, Both from clear day cables and then building my own from Neotech Silver. Overall i found the sound transparent but fatigue would creep on session that lasted over an hour.

Neotech Hook up Copper Solid may work but their is a seller on Ebay selling Neotech cables for cheap.
