Best interconnects & speaker cable? I don't get it


I don't know if there is a question here but I'm posting this to see if there is something I'm missing or overlooking in this observation. To the point, I've read many posts arguing the benefits of one or more conductors over others and I almost understand some discussions regarding, at least, comparisons of wire gauge for speakers. Maybe it relates to my less than well developed ability to discern subtlities in sound quality but I really can't hear much, if any, difference between interconnects or speaker cables.

As an example, I was recently experimenting with an amplifier selector (Niles DPS-1) which can accommodate a max of 14AWG speaker wire. In doing so I had to disconnect my existing cables which are "high end" 12 gauge per leg bi-wires. In making this comment I realize that just because my old wires are big and expensive does not necessarily mean they are the best match for my system or even any good. But...even though I think I am able to hear some small difference between them, to say that I think one is better than the other would be a stretch.

It seems to me that there are factors that would logically lend to the issue of quality, the primary of which would be conductor resistance and/or impedance. However, for transmission of line level signals, I can't see impedance as a significant factor.

All that being said, I believe that some listeners with acutely honed abilities can actually hear these differences and, in a way, I am somewhat glad that I don't; It makes wire choices much easier and way less expensive.

My current system consists of Shanling S-100 CD player, CALSigma 2 DAC, Rogue Audio Sphinx and Martin Logan Odyssey speakers with various interconnect and speaker wires.

I have a couple of extra pairs of interconnects laying around Jim, but for the most part, I sell them when I am done using them. I don't let them sit in a closet until they have no value. Keep the winner, sell the loser. I've gone through 7 pairs of speaker cables in the last year alone, I currently only have 2 pair, I've sold the rest. I've lost track of how many interconnects and power cords.

I find that using the Audiogon buy 'n try method works better for me than using The Cable Company, as I tend to lose less money. However, you do have to sell the cables you are not using for this method to be successful. If you are a herder, buy 'n try is a bad idea I suppose.
Its only money , not something really important like a new Purcell album .
Or reminding yourself to send an equal amount to Doctors without Borders or the Child Fund.
Frogman, what I've noticed is that most people, including me,
tend to make things that are only difficult, into something
much more complicated than it really is.
Easier to rationalize not doing it.

I used to think that type of thing was good, but have since changed my mind. Before we had things like Ebay and Audiogon to use as resources, you had to be much more careful. When you can't get rid of a component easily, cables or otherwise, you tend to put a lot more effort into getting it right the first time. The internet makes it too easy. I think its the biggest problem in audio today. People are getting lazy and making bad choices because of it. Its a cycle that feeds on itself. I see a lot of people getting sucked into audio because they hear the potential, but they lack the skills and experience too get all the variables right.
