Doubling a Set of Speaker Cables

Ok thanks, Doug. 
Have you noticed a certain gauge where there’s no real difference?

For example I see certain top of the line cables from Dana Cables and Shunyata going down to 2 and 4awg, respectively. Seems like overkill, but is there a gauge in which you believe you get the most bang for your buck? Maybe 6 or 7awg?

Hi Everyone,
Having bought the entry level Audio Art Classic speaker cables unintentionally twice the length I needed, I simply cut them in half, twisted them and crimped new plugs onto them and reinstalled them . This made an amazing difference. All the cliché descriptors apply, opened soundstage, increased transparency, detail, etc.
Anecdotal I know, but very pleasing to me. These are 14 gauge copper/silver cables doubled into old Snell Model As, Musical Paradise MP501 amp....so not high end...but good enough to hear the difference. I wonder if this is just a great money saving "hack"? Maybe. But again...no science here.  

At the risk of over generalizing, would two runs of a lesser cable produce a better sound than a single run of a better cable? 

For example, should I buy two pairs of wireworld eclipse cables at $1500 per 2mtr pair, or a single pair of silver eclipse at $3100 per 2mtr pair?

I have been using my DIY solid silver .9999 speaker cables. It is made up of multiple various gauges sleeved individually in there own teflon tubes.

Another Audiogonner wanted me to try a set of copper foil speaker cables which he raved about. When I did, I gotta say that I was not too impressed. It lacked bass and the upper frequencies. The music had no life.
(I must add that I also felt the same about the Silversmith Fidelium’s cables even though so many have raved about them.)

It could be that I am using tube mono blocks and this type of ribbon cables just don’t work well with this equipment. You know, impedance, inductance thing. I donna know, I just didn’t like the sound.

On a lark, I then tried both sets of the speaker cables together. That is; the solid silver and the copper foil... And I must tell you this combo worked great! The sum is better than the individual cables. Way better image solidarity and the frequency extremes are awesome. Just a pleasure to listen to.

Don’t dismiss something before you try it, you just never know.

It made day and night difference for me for my passive subwoofer.  The internal amp on my decade old PSB subsonic 6i subwoofer died.  I was using a radio shack PA250 amp to drive the sub.  Initially, I used a two feet long 18 gauge speaker wire to connect.  The sound was recessed.  Then, I used a three feet 14 gauge speaker wire.  The bass was immediately fully.  I was able to use some bass testing sound on youtube to measure the difference.  Then I picked up a long contractor grade extension cord from my neighbor's trash bin.  I cut a pair of three feet long, and striped three wire (black, green, white) on each end, and combine with a mono price Open Screw Type banana plugs.  Then the subwoofer made another day and night difference in extension and output.
Doubling speaker wire works well for any speaker can produce decent sound below 100Hz or all subwoofers.  For most stand mount speakers, the difference may not be heard by human ears.
