The StreamDancer DSD over USB2
A review found on our
Jena Labs StreamDancer USB cable:

here it is verbatim:

As with power conditioners and vibration control, speaker and
interconnect cables can have a sonic impact on system sound. The more
revealing my reference system has become, the more the subtle
differences between cables become evident. After experimenting with
many to find the best synergy for my own system, my quest led me to a
USB cable from Jena Labs. Made of braided, liquid nitrogen immersed,
high-quality copper, all the Jena Labs cables are hand-made in Oregon.
The cable enables wonderfully natural, rich sound, plus great
extension of lows and highs without any harsh etch that can accompany
higher frequencies with some cables. I keep several other high quality
USB cables on hand for testing, but none get as much dedicated
listening time as the Jena Labs USB.
More info relative to the USB cables we make.
We can and do build the StreamDancer to many different lengths....We have
made them as short as 10 inches and as long as 7 feet... We simply list
the 5 foot length as that is a popular selection that most people choose.
You can order any length you want. however the cost to make is not a
linear progression.. the basic price up to 5 foot is $500.00 past that in
length the cable is a factor in physical management so it will cost a
little more.
Lengths over 10 ft please ask us how much.

The use of Copper...
We don't like silver for music..it is great for Direct Current as you
find in power supplies, and would use silver in that application without
hesitation, but has some high frequency artifacts that we don't like and
hence, never use it for audio signals. Distortion is not real detail, but
some people think it is.
Our copper is exceptionally high purity and long linear crystal
composition. Yes these are important. OFC copper [ 4-nines ] is not pure
enough. OFC grade usually contains too much silver, bismuth, antimony, and
a few other minerals, that break up the crystal structure. Our Immersion
Cryo process also increases the quality of the crystal structure, far more
so than regular vapor cryo mostly used by others.
Break-in time:
Even a good cable break in machine can not substitute for use in actual
system to achieve final settling, but it can speed things up. A day or two
on a cooker can take 3 or 4 days out of total time needed in system. Your
going to get to that eventual time anyway, just listening, so why spend
money on a cooker when you can spend the same money on more music? To me,
more music selection is better than spending money on a gadget that is
rarely used, and only does a partial job at best. If you already have a
cooker, yes, use it, but final break-in is a complex process that requires
being in the system of use, so all the electrostatic potentials and signal
bandwidths are as they are and will be in actual use.
Why Custom made lengths:
We build all our cables to the customer's specific order. We do not have
inventory pre-made. There are so many options over our entire range of
products that we build, it would be impossible to have pre-built inventory
just laying around, and be assured that we would have exactly what someone
wants.
Why we do not shield the cable:
In the StreamDancer, the 2 data lines are a tightly twisted pair, as per
the specification protocol of the USB standards. We have not found it
necessary to shield them. Adding a shield will increase the parasitic
capacitance to ground for each line in the pair, and reduce the bandwidth
of the transmission line. You would hear that as a drop in transparency or
detail. There may be a rare circumstance come up some day, where due to
very high RF field in a given location, the trade-offs involved may well
favor shielding the data lines...but we have yet to encounter that
situation. If it is needed, we can do so with a grounded braided copper
shield applied over the data pair, and the DC lines braided over the
shielded data line. Yes, it is very possible to do so. but not needed in
normal circumstance. And due to slowing of rise-time due to capacitance,
not desirable unless absolutely needed to eliminate another problem that
is greater in magnitude than the losses of the cure.
If you have other questions, we are happy to try and answer them.
