For a while, the audiophools were hawking the benefits of using 300 ohm
twin lead (old school TV antenna cable) as speaker cable. It's about 22
gauge stranded wire. Of course it had to be raised off the floor by
little bridges every six inches, made from a rare crystal mined by
virgins in the Himalayas and carefully carried by yaks to Japan where it
was polished, packaged, and sold through high end audio dealers.

Okay, this is another issue.

Many people in the high end community are using older loudspeakers that were
designed to be driven by tube power amplifiers with fairly high output
impedance. These speakers are voiced for a source Z of a few ohms. Put them
on a modern power amp, and the low end disappears.

So... people drive them with tiny wire, and they add a lot of source impedance
and reduce the damping, and all of a sudden the speakers sound a lot better.
They could have just stuck a 2 ohm wirewound resistor behind the speaker, but
instead they use funny cable.

Again, these are issues that show up very clearly in a null test! It is
really, really interesting listening to what goes into the cable and what
comes out the other end with an Altec A7, because you can hear how dramatic
the mechanical resonance of that 515 is.
