SPM was highly regarded as one of the best cables in
the world. SPM cable is capable of the
highest resolution and is used by some of the most discriminating audiophiles.

 DESCRIPTION: 

* Insulation: High purity class 1 extruded Teflon 

* Conductor: x32 optimized diameter 

* Material: 75 microns extruded silver over 99.999999% OFC 

* Capacitance: 7.9pF/ft 

* Inductance: 0.12uH/ft 

* Propagation Delay: 95% speed of light 

SPM interconnect has 16 conductors, 8 per signal polarity.
All 8 of the + wires run parallel to each other with great precision in the
evenness of the spacing. In the center of the cable is a narrow gap followed by
the remaining 8 wires. Each conductor is 32 gauge and rectangular. The copper
used is "eight nines," meaning purity of the copper is 99.99999999%
The copper is silver plated. The insulation is Teflon, continuously extruded
over the 16 tiny conductors. The Teflon has a lavender tint to it making the
appearance that of a transparent lavender ribbon with 16 parallel silver
threads through it. Quite nice looking. Terminations to the RCAs or balanced
XLR connectors are finished with white (left) and lavender (right) heatshrink.
The interconnects have extremely low capacitance and inductance, some of the
lowest figures available in high-end interconnects. Impedance is another story.
At 110 ohms, these interconnects are obviously not in "the bigger the wire
the better" school of interconnect design. Nordost has attempted in the
SPM series to get the signal to move at the highest possible rate of speed
along the cable while delivering all audio frequencies at the same time. The
impedance of these cables is intentional and likely results from Nordost’s
study of audio signal propagation speed.

Nordost has made measurements of audio signal propagation in
SPM wires and other high-end wires. They show typical high-end cables/wires to
propagate audio signals in the range of 50% - 70% the speed of light. The speed
of light is the theoretical maximum speed an electrical signal can move through
a wire if everything is perfect. Nordost’s SPM Reference propagates signals at
95% of the speed of light. I can’t say for sure if propagation speed affects
sound quality of audio cables but Nordost isn’t taking any chances with their
top-of-the-line.

From Soundstage reviews: 

Being Beamed to Another Dimension Must Feel Like This 

So you innocently cable up your system with SPM interconnect
and speaker cable expecting some nice clean dynamic sound. What you get is
something very different. You get to find out just how screwed up other wire
is. My heart nearly broke. All those years listening to wires that sounded like
that when I could have been listening to wires that sounded like this. If only
someone had realized how screwed up audio wires were 20 years ago, we’d all be
20 years of enjoyment richer today. The congestion, confusion, lack of balance
and general lack of finesse of other wires was startling. I’m not referring to
$100 interconnects and $200 speaker cables either. I’m talking about $500 -
$1,000+ interconnects and speaker cables in the $1,000 - $2,000 price range
from manufacturers with well known names, great reputations, and lots of
glowing reviews. SPM Reference interconnects and speaker cables revealed these
other wires as unacceptable, period. I’ve never had anything quite like this
happen during a review before – one product simply blows out everything else
you have ever experienced before. The improvement is significant, easily
audible. Anybody can and will hear exactly what I heard. There is no subtlety
to it. You do not need "golden ears". You do not even need
particularly good hearing to recognize the difference. It is totally and completely
obvious.

Final Thoughts 

Having reviewing experiences like the Nordost SPM Reference
makes all the work worthwhile. There is no way to say for certain that SPM
Reference would be the best cables for your system. There is the problem of how
systems react to different wires. This can be unpredictable. What works well in
one place, with one combination of components, fails somewhere else. But do
know that Nordost SPM Reference is "out there" in a group with very
few members. Compared to the small "elite" cable group, other wires,
even other expensive wires, sound defective.

You have to appreciate products like Nordost SPM Reference.
While you may find the price out of reach, they bring a new level of
performance into focus. Suddenly the old world record has been shattered and
the bar has been reset to a higher position. Those of us who can’t afford SPM
Reference can look forward to the day when Nordost or somebody else figures out
how to get this level of performance down to prices we can deal with. If you’re
lucky enough to have products that perform as well as SPM Reference within your
budget, you can enjoy the performance now while the rest of us squirm nervously
wondering how long we’ll have to wait.
