Speaker wire construction and sound quality


I'm not new to mid to high end stereo listening but have concentrated, over the years, mostly on the obvious equipment choices such as amplifiers, CD players, loudspeakers, etc. Most recent decisions regarding these have been based on information and advice found through forums such as this and, for the most part, have worked out well.

In the old days (50+ years ago) when monaural was king and high volume strong bass reproduction was the goal of most young pursuers of high fidelity, speaker wire construction and quality were not common subjects of conversation. Everyday electrical extension cord in those days was the cable of choice. In the past twenty or thirty years my approach has not been that much different in that I have simply chosen specialized and relatively expensive heavy gauge wire and left it at that.

Things have changed. The choice of speaker conductor has become a big deal and I simply don't understand the technical arguments supporting one type or another of the available choices. For the most part I'm pretty happy with my system but am always looking for ways to reduce brilliance/shrillness which I am very sensitive to because of a hearing condition called hyperacusis.

I've tried some of the more obvious fixes such as tube based DAC's and they definitely have helped. FYI, my basic system consists of the following: Rogue Audio Sphinx integrated hybrid amp, Shanling solid state CD player, California Audio tube DAC and Martin Logan Odyssey speakers. This was not a ground up designed system, just what it has ended up being as a process of piecemeal evolution.

Getting back to speaker wire, is there really that much difference in sonic quality related to a choice of the many that are available? I've read many articles on the subject and the opinions vary greatly to the extent of being totally contradictory to one another. I don't have a super audiophile system, I know, but are there some basic considerations that one should take into account in making a choice, and is there any advantage to bi-wiring?

I'm not that good at describing sound character because I don't have a good handle on the terminology but I do know brilliance when I hear it. It was suggested by someone whose knowledge I respect, that speaker wire could have a positive effect in resolving the brilliance issue while maintaining detail. As an experiment, he loaned me a pair of cables that are highly reviewed and cost over $5000. I can't afford something like this but was curious to see if I could tell the difference; I couldn't. I even tried the same experiment with my pair of Jamo Concert 8 bookshelf speakers using the same music ( Jazz at the Pawnshop) thinking they might be more sensitive to subtle changes, and still could not discern a difference. I realize that this could be as a result of my own observation deficiencies but would very much like to hear what you all have to say about this issue.

Very nicely written post, if I may say so.

While speaker cables can make a difference in the direction you are seeking, to a greater or lesser degree depending not only on their own characteristics but on various technical characteristics of the speakers and amplifier they are connecting (more on that below), IMO the change you are seeking involves a much greater magnitude than cables are likely to provide.

My suggestion, assuming that you want to continue to use the Odyssey speakers, would be that you consider changing to an amplifier having a tube-based output stage. For two reasons:

1)As with most electrostatics, the impedance of your speakers descends as frequency increases, being spec'd at 4 ohms nominally but only 1 ohm at 20 kHz. As a consequence of the negligibly small output impedance that amplifiers having solid state output stages almost always have, the amount of power they deliver will increase approximately in proportion to a decrease in load impedance (until the amount of power that is called for exceeds their capability). That effect will occur to a significantly smaller degree in the case of amplifiers having tube-based output stages, because their output impedance will not be negligibly small in relation to speaker impedance.

Therefore an amplifier having a tube-based output stage will tend to deliver less high frequency energy to your speakers, relative to the amount of energy delivered at low frequencies, than will an amplifier having a solid state output stage.

2)Solid state amplifiers tend, more often than not, to use greater amounts of feedback than tube-based amplifiers, which in turn can enhance certain distortion components that are subjectively perceived as added brightness, even if the magnitude of those distortion components is very small.

Getting back to speaker cables, keep in mind that the sonic effects they may have can be expected to be proportional to length. The shorter the cable, the less difference it is likely to make. Their sonic effects can also be expected to be dependent on the impedance of the speakers (the lower the impedance, the greater the degree of difference cables can be expected to make); on how that impedance varies as a function of frequency; as well on various characteristics of the amplifier that is being used (including the amount of feedback, output impedance, bandwidth, RFI susceptibility, and other parameters).

Most of those factors have little correlation with the musical resolution and sonic quality of the system. My perception has been that audiophiles who strongly espouse the differences cables can make often tend to make the (IMO) mistaken assumption that the ability of a system to resolve musical detail and its ability to resolve differences between cables and other hardware go hand in hand, when in fact the opposite could just as easily be true in a given case, as could any partial degree of correlation in between.

All wire sounds different in different systems. The only way to determine if the cable works to your satisfaction is hearing what it does in your system. Sure, you can take suggestions, but there is no right answer but yours. The maker of my electronics told me they recommend Cardas - they even label their own Cardas cables....and to ME almost any other cable sounds better in MY system than does Cardas. I have heard Cardas sound great in other system, but not in mine. If the manufacturer of your speakers has provided 2 speaker connections for biwire.....it was designed with that in mind, and my experience proved that bewire does sound better. The most dramatic improvement using wire is from power cords, than interconnects, than speaker wire...in that order.
I'd agree with Stringreen. Also, try isolating specific details like a cymbal strike or a repeated piano note. Sometimes the difference between cables is as subtle as a little smearing of the image instead of a really sharp well-defined one. Also, certainly not intending any disrespect, not everyone's ears can hear the small, often subtle details between cables - or for that matter, different people might hear different things from the same cable change. Changing cables can make a big difference, or none at all if the person listening can't hear them. I have friends who can't hear any difference between lamp cord and expensive cables. They still love their music though.

If I smoke a bowl or a bong and play same track before and after, I can assure you that it's a great tweak and it works:-)
Remember the good old days lots of audiophiles did that simply because there was not as many choices as it is now.
