14/4 wire for speakers- good idea? Bad idea?

@argon66 - Cable geometry is key to producing a good cable, whether it be IC;s, Speaker or power cables.

Twisting the ends of a 4 conductor cable can be beneficial or detrimental - it all depends on the geometry of the conductors inside the sleeve and the conductors that you select to twist together
- you WILL also affect the capacitance and inductance of the cable which may be detrimental to the amp - some solid state amps (like NAIM, AYRE) can be driven into oscillation if a high capacitance cable is connected and you end up burning out the circuit.

I prefer to take a different approach...

This will approach almost eliminates any interference between conductors resulting in an extremely low noise cable

It also has low capacitance AND inductance parameters making it ideal for most amps and speakers.

@toddverrone, has provided a link to the Helix power cable above - he has tried all of the Helix Cables on my site - I think he likes them :-)

I’ve spent 4-5 years trying different geometries and conductors and the HELIX cables are the net result. The conductors identified on the site provide what I consider to be the best bang for the buck

I have compared them at length to a few commercially available cables costing substantially more (up to $2000) and the HELIX has the edge across the board everytime - i.e. dynamics, clarity, image, control etc...

Personally - I would NOT advise taking your approach - sorry :-(
It might work now - but it could damage other amps you might buy in future.
- it happened to a friend of mine with his Ayre - and he was using Cardas Cables

High end manufacturers don’t use this configuration, AFIK. (talking about starquad and equivalents)

It’s just that it is excellent and right in the correct area of design and requirements for big clubs or house systems, or concert performances, traveling road shows, etc.

Pro does not equal ’good’ or ’best’ ....It merely equals the requirements for pro use in ways that work and don’t fail. Functionality and not failing, the two big points. Performance quality is third or lower on the list.

If anyone asked my opinion on this for high end set ups, I'd say no, don't. For a few dollars more or spent differently, far better audio quality can be found. Star quad and equivalents are for ripping your face off with long term all day +1kw peaks on bass bins, flying monitors, 50-100 ft runs, and so on.

Excellent insight guys. 
My gear is not super high end...but certainly not cheap, so I most certainly want to benefit from the dollars spent to date....let alone have a configuration that may create havoc between speakers and amp. 

Point of note Im currently running a Bryston 3B3 into Volent VL3 Speakers. My preamps (phono and preamp are all tube...Zesto and Lamm ll2.1 respectively). I started upgrading interconnects with a mix of Morrow and Transparent cables (all about 200 bucks used). 

Sounds like its time I did something with a better design for speaker cables now. 

More suggestions in the $200+ used range?

@argon66 - you might want to consider the Van den Hul CS-122 bulk cable.

VdH’s D-352 provides better bass, but it’s a little more expensige

The CS-122 is a great sounding bulk cable and extremely well made.

You can "augment" the clarity and dynamic performance simply by removing the flat center insulator strip and spacing the conductors approximately 1" (or wider) apart. You don’t have to be accurate with the spacing either - just keep the two conductors separated.

This cable is designed for car audio use - hence the little strip of insulator in the middle - keeps things neat and tidy

I’ve tried splitting the conductors with the CS-122 and the D352 and they perform so much better.

Beware of counterfeit products on the web.

I had them in my systems for many years - until I was introduced to the KLE Innovations speaker cables - then I developed my own and the rest is history

Also - if you are using banana plugs on your cables - you might want to consider these

The are by far the best Banana plugs I have ever tried - bar none. The provide the best clarity, dyamics, image, bass and control

Good luck with your quest - steve
