Enjoyed reading your white paper.
A lot of work went into this analysis and I commend you for it!
Question: Why did you use long 7 meter cables?
Most people would use 3-10 feet in their application. (which would skew the results in a positive way for all cables tested)
I use Hales Signature Two's with a 4 ohm input.
For speaker cables, the new Silversmith Fidelium.
Separate positive and negative leads are used in the design, raising the specter of low capacitance and high impedance due to a wide separation between the two conductors. (in my case, varying between 3"-8")
Despite this fact, the cables are amazingly neutral and balanced throughout the frequency spectrum.
The transient response on the leading and especially trailing edges are SOTA.
The imaging and sound stage are killer!
They exhibit no edginess or brightness. (especially when compared to the Straightwire Maestros that I formally used)
I might chalk it up to dumb luck that the impedance's between Amp,. Speaker Cable and Speaker apparently match up well.
But many other people who use this cable in very different set ups, feel the same way about this cable.
I could easily experiment by overlaying the cables and taping them together.
From a sonic POV, what improvements would I expect to hear?
