Can speaker cables be too thick?

Hi folks, I've tried several speaker cables in the past, like the MIT MH-750, Wireworld Gold Eclipse, Ridge Street Audio, Pure Note Paragon and Cardas Golden Eclipse. I've been using these expensive cables until I replace them with ordinary 2x6mm2 OFC copper cables consisting of multiple small gauge solid conductors. These cables have the best tonal balance and they match very well with the speakers (Dunlavy SC-V). I use them in biwire fashion (each cable is 5 ft in length). What would happen if I replace them with even larger gauge copper cables, like 2x8mm2 or 2x10mm2? Would the sound improve further with the larger gauge cables? What sonic characteristics can be heard when the speaker wire is "too thick"?

Thin-wide (flat) conductors are best for radio frequency signals. The misapplication of this true fact to audio frequency signals is typical audiophile science.

That said, my speaker wires are flat. However, the reason is that they are Goertz, and the two thin conductors are one on top of the other so as to create a relatively high capacitance. The shape of the wire is not a factor.

The proof is in the listening, musical instruments and voices gained a normalcy with decidedly more detail over the round wire. If there are radio signals getting through then I do not hear as well as I thought. The painter that is working in my room now, somewhat younger, says the same.

A frined of mine who is a electrical engineer put togeather a pair of 10" speaker wires made from 6-awg wire. They sounded more detailed but somehow not in a good way? I took them off and went back to my 12AWG wire.. Biggest difference I have heard so far is the change in the power cord.

I have made 10 awg cables in a bi-wire setup for my speakers. I did this as an experiment...It turns out that they sounded more detailed and had a much cleaner soundstage than my Nordost Blue Heavens that I was using before. See the cables in my system home. I found these cables to be great, and they didn't take too much work and cost a fortune.

Hi Ben, have you ever done any experimentation with thicker cables (less than 10AWG)? If yes, what are your findings? I'm curious if there is some maximum cable (conductor) thickness that could result in sonic improvement. Surpassing this thickness would not give any further improvement but probably deterioration of sound.
