Are You Screwed?
Vibration! What havoc it can reap! When I mention vibration, most of you think about turntables, speakers, CD players and the like...the things that vibrate in our system. Is this going to be a discussion about vibration control? Well, in a way.
Right now I want you to slap on a nice CD or record and play some music. Listen carefully to what you hear. Listen to the focus, the sound stage, listen to how 3-D it sounds.
We will pause as you listen..........
All done? Now...get up out of that nice recliner and get a screwdriver. (Not the drink! Get the thing you hold in your hand to tighten screws!)
Now...Go over to your speakers and plunge it into the paper...JUST KIDDING! No, really... get down and locate all the screws that are holding the driver(s) in. What you want to do next is tighten all those screws...not too much, just enough to make them snug. Were you surprised as to how loose they were?
Now, go take another listen to the same piece you were listening to before... What do you think? Sounds better right? More pure, more focused. Your speakers have been in motion against their cabinets all this time. Something had to give, nd it was the screws that hold them in place! What a free tweak!
We may not realize it, but as we played our music over the months, those screws were getting looser and looser... and so was your music. Vibration has more ways of getting to us than is immediately obvious.
Do you play CD or have a transport? Open it up and look for the screws that are holding the main transport mechanism in. Do so at your own risk though.
These screws can also come loose as your CD 's go round and round, causing vibration to go through, loosing the screws that hold it all together. Tighten them down to a safe degree. No listen to the improvement!
*Morrow Audio Cable Theory: *
In this issue we explore the theory behind the Morrow Audio cables. Some have seen this and some have not. At any rate, it is an interesting study:
The Morrow Audio cables differ in 3 major areas from most other popular and often expensive cable designs. We will now explore these areas... But first...
How Do Your Cables Measure Up?
Check the boxes that describe your present cable design...
- My cables use stranded wire in their construction. ?
- My cables use large gauge internal wires, larger wire than 24 gauge. ?
- My cables are encased in an insulation jacket. ?
- My cables are covered with a decorative mesh netting. ?
Ok. Are you finished checking the boxes? Let's see the result...
- 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.
"I hear a beautiful, natural, extended frequency range top to bottom, with a spacious, airy soundstage. I'm enjoying gorgeous, dynamic music, with a natural sense of performers, instruments, musicianship and recording venue."
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.
"I retired as an electrical engineer 15 years ago and this cable was a breakthrough for me. I was hearing a wide, deep soundstage, with really good but not over-etched detail, with instruments and voices sounding so much more real than ever. Bass was very clear, mids were delightful, and highs were clean."
3. Cables That Use Cable Jackets Or Heavy Insulators:
Some cable designs use decorative 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.
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".
Laser adjust your speakers:
Here is a fast, easy and accurate way to toe-in and level your speakers evenly.
Go buy a laser level that has a flat side opposite the laser end. Take it and hold it flat against the speaker, near the midrange driver with the laser end firing toward your listening chair.
Notice where the laser hits on the back, front facing of your chair. Is it near the center, more toward the outside?
Move the speaker where the laser hits where you would like it. You can also adjust the height of the speaker as well with this device.
Now, once you have adjusted your speaker where you desire the laser to fall on your chair, do the same for the other speaker. If you desire the laser to hit dead center where your head would be if listening, adjust both speakers so that the laser point falls on the same spot on the chair.
If you like a little toe-out, adjust the speakers so that the laser hits on places outside the center mark of the chair, both adjusted evenly so that they are both outside that point.
Sit down for a listen! Is' ent this hobby fun!
