Morrow Audio SP2 Reference Cable...

Problems With Popular Cable Designs...Do your cables possess these?

The Morrow Audio cables differ in 3 major areas from most other popular and often expensive cable designs. As you read about this, you may realize that your cables have problems in these areas. Do not despair, you now qualify for a dramatic improvement in all areas of sound with the Morrow Audio line of cables. After hearing our properly designed cables, many of our customers replaced the ones they had with our complete cable product line.

1. Cables That Use Stranded Wire:
In stranded wire designs, the strands touch each other hundreds of times at various points along the length of the wire, causing the signal to jump from strand to strand instead of flowing through a continuum. The result is a diode effect (like little mV Diodes) at each point where the strands come into contact, causing distortion of the signal; blurring imaging, soundstage cues, etc.

Another explanation of the diode effect is oxide forming between the strands which encourage a non-linear conduction. At the points where this occurs, actual RF detection can occur, turning your cable into a radio; receiving, detecting and injection RF signal and distortions into your music signal.

In my experience with stranded cable, where each single conductor is made from several strands, not insulated from each other, there imparts an unpleasant harshness and brightness to the sound.

The Morrow Audio Design:
Morrow Audio signal cables use ONLY solid core wire, NEVER stranded. We eliminate all diode effects by using only solid core wire. You will hear much more information in your music that was lost from the smearing effect that stranded wire produces.

Some of our models contain multiple runs of wire. They are mono strands, individually insulated from each other. In the case of our MA2 Reference interconnect, these multiple runs yield a more detailed sound. The speaker cables, out of power handling necessity, also contain these multiple runs of wire.

2. Cables That Use Large Gauge Wire:
Different frequencies tend to ride at various depths in the wire structure; the highs, mids and lows tend to separate which cause time and phase errors in the signal. This is commonly known as the "skin effect". When a large gauge wire is used, this problem is even greater, resulting in phase and timing errors. The soundstage is reduced, instrument timbre is distorted. See photo below...

The Morrow Audio Design:
Morrow Audio signal cables ONLY use a small gauge wire. The different frequencies ride at the same plane in the wire, resulting in less phase and timing errors. A more accurate sound is the result. The soundstage is huge, instrument timber is accurate, it seems like the performers are in your room.

3. Cables That Use Mesh Cable Jackets Or Heavy Insulators:
Some cable designs use decorative mesh cable jackets or even heavy insulators to insulate and/or make their cable attractive to the eye.

Inside common cable designs are internal conductors with an extruded insulation of some sort. The insulation material is in close and immediate contact with the conductor along its entire length. One of these conductors might be in the form of a wire mesh that surrounds the center conductor, acting as a shield from RFI.

Wrapped around all this is the outer casing of the cable, made out of rubber, PVC, Teflon or some other material. Finally, there may be a decorative mesh netting around all this, the only purpose of which is to appeal to the eye and make the cable attractive.

These insulation elements all form the dielectric of the wire, which has a tendency to absorb and release energy to and from the conductors. This occurrence produces a negative sonic affect; smearing of the signal and other distortions. The greater the number of insulating layers there are, the greater this distortion will be. The thickness of these layers is also a factor of concern, with thicker layers being the worst.

Have you ever heard of speaker cable lifts? They are little stands that lift the cables off the floor, improving the sound. The improvement comes by keeping the electrical field from reflecting back into the cable off the floor. Why then do cable manufacturers apply decorative mesh, thick insulations and other signal distorting elements in their design?

The Morrow Audio Design:
Morrow Audio cables DO NOT use decorative mesh jackets or heavy insulators. Each strand of wire incorporates a very thin insulation and are bundled together with small pieces of heat shrink every 6 inches. This allows the least amount of reflection back into the cable, retaining the quality of the music you love.

Morrow Audio cables are not as attractive as other designs, but it is the music that counts! With Morrow Audio cables, your music will flow unhindered, resulting in greater realism as well as longer and more enjoyable listening sessions. Those who have have heard our cables describe it as a "Listening Experience".

Testimonials

Very natural sound. Can't imagine anything better...
"I just wanted to send you a personal note of thanks….for providing some really excellent products.  I‘m amazed at how much the sound improved after the break in period.  I could hear early on how good the clarity and definition were.  Now there is substantially more bass with no loss of clarity/definition.  The midrange/highs (which initially sounded a bit clinical) sound very natural, with just a slight touch of warmth (maybe the amp).  And that isn't’t bad as I have a fairly small listening space!  I can’t imagine other cables at any price improving on the sound.  It’s that good! Best wishes!"

Stunned as to how transparent they are...
"The SP2 exhibited great detail, transparency, neutral tonality from top to bottom, openness and focus, and rendered both voices and music with an uncanny glimpse of reality. The SP2 had a wonderful synergy with the amp and speakers, seeming as if they were non-exsistant. The SP2 has a remarkable ability to disappear. I was quite frankly stunned by how transparent they are. Settling on the MA2 interconnects and SP2 speaker cable, I wanted to shower them with many positive adjectives, but then I thought, how does one do that to something that doesn't exist? They are that good."

Better than Anti Cables...
"Mike, I have the SP2 cables and am delighted that they worked out very well in my system. I have always expected silver plated cables to give a bright sound, thin tonal balance and weak bass. My previous cables is the Anticables (all copper, solid core wire), I am also using a flea powered amp (2 watter). I am always hesitant to use multi strand cables, those that I had in the past tended to slow down and muffle the sound; perhaps due to a lack of drive from my amplifier."

No negatives...
"Your SP2 cables came highly recommended by my friend who is using them in his system. After plugging the new cables in my system, it sounded good from the get go. It has none of the negatives that plagued me from trying silver plated, multi strand cables in the past."

Fast bass & extended highs without the expense of refinement...
"Some noticeable differences between the SP2 and the Anticables in my system are that the SP2's have better and more extended highs. This does not come at the expense of refinement. Mids come with more projection into the soundstage and the bass is definitely faster. It has the snap and punch that I desired in my system. Before I wondered whether it was my amplifier that was the weak link in my system, not anymore!"

They aren't going anywhere!
"I tried them and love it. Yes I know that more time will be needed to do any serious evaluation, but right now all I can say is that they aren't going anywhere!"

Increased clarity and definition...
"Increased clarity and definition of instruments top to bottom with the SP2's. Excellent performance at a reasonable price."

Very impressed...
"Just want to let you know that I am very impressed with the SP2 cables. I have close to 200 hours on them. You article on break-in is right on the mark. Great product!
