After some extended listening/testing I find the treble slightly subdued and repressed with the Fusion compared to the Belden 1505F cable I normally use. While the Fusion certainly is better than stock ICs and slightly better than the Monster Interlink 400MkII in terms of clarity, the Belden 1505F is that much clearer and more open. Of course, since these are ICs the differences I speak of are very subtle. Here is what BlueJeansCable said about the Fusion (I provided them with pictures but they didn't have the actual cable in their labs for testing capacitance/inductance/etc.):
“Well, it's hard to tell very much from the photos. If I'm interpreting what
I see correctly, it appears to be a shielded "star quad" audio cable. Star
quad is a configuration where there are four conductors twisted together,
and opposing pairs are joined at each end. (That is, the two blue conductors
should be opposite one another, and the whites opposite one another, so that
when the raw cable is viewed on-end, the order, going around the cable, is
blue-white-blue-white) The purpose of this configuration is to maximize
noise rejection in balanced circuits, and it's very effective, as contrasted
with a standard twisted pair. However, as a general rule that's only going
to work if the circuit is balanced. If it's running to unbalanced circuits
(e.g., pretty much anything connected using RCA plugs), common mode noise
rejection doesn't work (or, at any rate, isn't very effective) and so the
advantages of the star quad disappear.
The downside of star quad is its high capacitance, which can contribute to
high-frequency rolloff. How significant that is will depend on cable
length, the actual capacitance rate per foot, and the input and output
impedances of the devices being interconnected.
I can't tell what the shield is made of. Ideally it ought to be copper, but
it's possible that's aluminum; trying to solder to it would probably tell
you, as aluminum doesn't readily take up solder. It looks as though these
might be drain wires for a foil shield, as there doesn't seem to be enough
shield wire coming out of the bundle to make up a full braid--but that may
just be how this sample was trimmed.
Cable like this should generally work well in balanced audio, and acceptably
in unbalanced audio (though I'd avoid long runs in either due to the
capacitance). It's meant for analog only and should not be used in
high-frequency applications (video, digital audio) where cable impedance is
a factor.
The ferrite core won't do much, though it should not hurt anything; it acts
to choke off RF on the shield.
As for the cable being "directional," generally that doesn't make a lot of
sense. One would really need to know why the manufacturer contends it's
directional in order to evaluate the claim. Sometimes a cable will be built
with a "floating" or "telescoping" ground, where the shield is grounded at
only one end of the circuit, and in such cases, the direction of hookup can
matter. The purpose is to prevent ground loops, and it really only works,
again, in a balanced circuit. In a balanced circuit, the ground isn't the
signal return path, so one can break the ground without problems. When this
is done unbalanced, usually what happens is that one side of the pair (in
this case, one pair of the quad) is connected to ground on both ends, but
the shield is connected to ground only at one end. The problem, of course,
is that you can't break up a ground loop this way because the grounds are
still connected.
If that's not the rationale for it being "directional," and the rationale is
instead something funky (e.g., "the microcrystalline structure of the copper
has been aligned to optimize in one direction") then that's just nonsense.
All analog audio signals, balanced or unbalanced, flow as alternating
current, so even if there were such a thing as optimizing the wire to flow
one way, it would be a bad thing to have such a cable; one needs the
electricity to behave the same on the positive as the negative phase.
Considerations as to quality which I can't judge from the photos would
include: shield coverage percent; shield material; consistency of twist rate
and wire spacing; and probably a few things that don't come right to mind.
