Speaker cable -no shorter than 8FT? T or F

As far as speaker cables needing to be at least 8ft. I don't know?? I haven't heard many monoblock users buying 8ft cables. I actually hear some audiophiles wire directly from amps to the speaker internal wires,eliminating speaker terminals.
I would assume this is as short a path as you can make.So what does that tell you?
Some of his ideas sound reasonable but others not.

Year after year, there are many new components.. pre-amps, power amps..etc. that rave on about how they have shortened the single path and length of internal wire.

Listen to them...the shorter the interconnects and speaker wire..the better.

Keep this in mind on the Mapleshade comment,amplified
loudspeakers must have very short runs inside the cabinet.

There is no technical reason for this. With all cables, shorter is better with perhaps one exception.

With transports that have slow signal risetimes, in order to avoid reflections that can cause edge jitter, it is prudent to use S/SDIF cables that are at least 1.5m long.

Any of you old silver backs, like me, remember Bob Fulton and his Fulton Gold cables? All the rage in the '70s. These cables were 2 gauge (!) and Bob only sold them in specific lengths. I had a pair of his 57" on my subwoofers for years. Bob claimed that 57" was the correct length, not 5'.
