Speaker Cable Questions


Opinions please:

(a) For lengths of approximately 25 feet, is 10 gauge wire preferred over 12 gauge? I suppose 10 gauge is always preferable to 12, or is it?  

(b) Everyone on this forum knows how expensive "quality" cables are. While I haven't checked extensively, I have yet to see any of these quality cables available in 25 foot lengths. if they were I would have to mortgage the house  to buy into them. So the question here is what are the "best" (somewhat subjective I know) cables at 25 foot lengths? (cost no object answers as well as costs commensurate with an Musical Fidelity M6si amp welcome).

LAT International (and many other places I'm sure) will build you any length you want, and terminate the cable with the connector you want, and the quality will be excellent. Have you checked LAT? No affiliation.

There's no best. I remmeber when 22AWG "hookup wire" was the rage. Flat cables, ribbon cable, solid core, skin effect, keeping wire off the floor, short runs of coat hangar wire.
Thanks rail2rail. I just checked the LAT International website. " 900 SIGNATURE 2 WIRE speaker cable" is there best speaker cable and I could probably get away with a 20 feet run, so no need for for custom length. Interesting though that given their somewhat detailed description of their silverfuse process, they do not speak to the end result gauge of the wire. From the picture I glean it would be 12 gauge.
Try Signal Cable. They will make custom lengths for you, and are very good cables. Price won't break the bank, either. I've used them for many years, interconnects and speaker cables.
