Cable Design Improvements

 

Morrow Audio is always looking for ways to improve the design and sound of our products. This page shows the history of those changes and improvements. These are arranged with the latest change at the top.

Due to these changes and improvements, there might be slight variations to the appearance of the cables shown in the photos on the website until we update the photos.


6/8/2021: 100% cotton outer braid implemented on our Anniversary line of cables.The color is more black than shown on the product photos, which will be updated in the future.


5/12/2020: Wire runs were increased in our Speaker Cables over the 2018 wire count:

SP1: Original pre-2018 design: 12 runs. 2018: 48 runs. 2020: 64 runs.

SP2: Original pre-2018 design: 16 runs. 2018: 84 runs. 2020: 112 runs.

SP3: Original pre-2018 design: 24 runs. 2018: 144 runs. 2020: 192 runs.

SP4: Original pre-2018 design: 48 runs. 2018: 288 runs. 2020: 384 runs.

SP5: Original pre-2018 design: 72 runs. 2018: 432 runs. 2020: 576 runs.

SP6: Original pre-2018 design: 96 runs. 2018: 576 runs. 2020: 768 runs.

SP7: Original pre-2018 design: 120 runs. 2018: 865 runs. 2020: 1153 runs.

Elite: Original pre-2018 design: 192 runs. 2018: 1152 runs. 2020: 1536 runs.

Anniversary: Original pre-2018 design: 288 runs. 2018: 1728 runs. 2020: 2304 runs.


 9/1/2018: Major Design Improvements:

The below design changes were incorporated on 9/1/2018 for the following cables: DIG cables, interconnects, speaker cables, speaker jumpers, subwoofer cables, REL subwoofer upgrade cable, Y cables, mini & patch cables:

1. More Runs of Wire
We have added more runs of OFC (Oxygen free copper) wire to each cable model. For instance, the MA1 interconnects, which previously had 2 runs of wire per channel, now has 8 runs of individually insulated wires per channel. The Anniversary speaker cables, which previously had 288 runs per channel, now have 2304 runs of individually insulated wires per channel! This provides amazing improvements in all areas of the sound: air, soundstage, musicality, realism, harmonic structure, etc.

2. Progressive Smaller Gauge Individual Wires
As you move up the line, the gauge of the individual wires in the cable structure reduces. Smaller gauge individual wires result in less skin effect distortions.

3. Larger Total Gauge
The total combined wire gauge has increased for many models, providing lower impedance and improved signal transfer.

4. Improved Dielectric
We have greatly improved the dielectric (wire insulation) in the design by introducing cotton. Cotton has the lowest reflectivity of all dielectrics which reduces the "smearing" distortion found in others.

5. Lower Noise Floor
Our new manufacturing process insures a tighter, more uniform, internal wire weaving. The cables are quieter, rejecting more RFI than before. You hear deeper into the music, subtleties before unheard now come through with profound realism.

6. Solid Copper Instead of Silver Coated Copper
We no longer use silver coated copper wire, only solid copper wire for each individual SSI strand. The presentation is now smoother and more musical. You will re-discover recording after recording, hearing things you never heard before.
