Why Do Cables Matter?

 Open any amp or speaker and tell me what kind of wires do they use to connect them with? Copper AWG

                         The usual ignorance (willful, or otherwise).

                                         A FIRST PAGE replay:

        Many upscale equipment designers do use better wire within their products*, or: offer such as an upgrade.

         Even companies that manufacture PC boards take into account the dielectric constants of the material used and their effects on signal speed, among other factors.

               *ie: David Manley (of VTL) was already using George Cardas' wire, internally, back in the Eighties.      Emerald Physics offers WireWorld, OCC internal wiring, as an option/upgrade.

    Then too: the typical SS component's total internal wiring can be measured in scant inches (copper AWG or not/if any at all*) and thus: inconsequential.

     The combined total, internal wiring of my PTP wired, Cary valve monoblocks = 16".

           *Many have all inputs, outputs and AC/power supply, attached directly to their PC boards.

Thank you for the inspiration.

but I would never spend more than a couple of $100 on them.

Wait till you hear better sounding interconnects. You might then gladly part with money to own that sound. ☺

If you ever decide to purchase expensive cables, buy second hand. I got my AQ Fire RCA cables for 1/4 of the original price.

I found this tutorial for a DIY interconnects using silver wires with interesting aircoil design geometry aimd to achieve low L and C.

How do they sound?

We have tested these cables in several systems and configurations. Tubes, solid state, single ended, balanced, lengths ranging from 70 cm to 2 meters: there was never any issue of compatibility. I cannot honestly say they were clearly better than every other cable they were compared with, but for sure, they weren’t inferior to the other cables and, in many cases, we are talking about cables that are very, very expensive and exclusive. Several times the owners of the systems asked me to make, for them, some cables to replace those they had. Overall they are excellent, but in my view, they excel in four aspects: bass frequencies, soundstage, time coherence and speed. In bass frequencies the increase of clarity is evident; thin solid cores remove the bloat generated by thick fat cables, clearly improving the quality of sound. Thin wires minimize time smear allowing a much better coherence across the entire frequency spectrum. Low capacity design and no screening means a cable that is super fast in responding to transients. Honestly, I don’t have a good explanation for the soundstage, but width and depth of the virtual stage are substantially increased where the system allows for it.

Better crossover components in speakers make a much bigger improvement in sound rather than replacing the internal wiring.  Replacing the electrolytic capacitors in less expensive speakers with roll film caps or at least bypassing the bigger electrolytics with a small film capacitor is the biggest bang for the buck.  I was doing that back in the 1990s.  Better inductors and resistors in the crossovers will help too.  Then after all that, internal wiring may or may not make a sonic difference.  It is typically not too difficult to get to the crossovers in speakers.  Film capacitors for a given value can be quite a bit larger than their electrolytic counterparts.  That’s why sometimes it better to just put a small value film cap in parallel with the large valued electrolytic.  Gain most of the improvement in sound that way.

I’ve been a lifelong music lover, so I’ve also been pursuing audio systems and upgrades that get me closer to live performances. I recently upgraded my interconnects from Kimber Hero to AudioQuest Dragon (read Robert Harley’s review in The Absolute Sound).  My Speakers sounded more alive, more detailed in the midrange and highs, and better controlled in the bass region. I am now planning to upgrade power cables.
