Canare LV-77S Precision Coaxial Digital Audio Interconnect Cable

Canare LV-77S Precision Coaxial Digital Audio Interconnect Cable with Canare "True 75 Ohm" Connectors

This Canare LV-77S Precision Coaxial Digital Audio Interconnect Cable is made with Canare's incredible LV-77S double-shielded cable.

This Pro Series assembly features Canare's high-quality, "True 75-Ohm" connectors, fitted with distinctive orange silicone strain-relief boots, which provide CEA-standard color-coding while also helping to avoid sharp bends at the connectors.

RCA connectors are our "standard" for this cable, but if you prefer, you may also specify BNC connectors for either or both ends.*

Extreme Overkill

Take a look at this cable and try to take in the scale of it...it's big cable...nearly as big as the body of Canare's RCA connector, and Canare's RCA connectors are not insignificant in size!  This is serious cable, and it can deliver serious performance.

When we first started selling Canare cables, we thought that their LV-61S would be all the cable that anyone would ever want or need in a non-commercial A/V system.  After all, it's high performance cable that out-performs many higher priced options.  It has a professional look and feel, and it delivers long-term performance, so why would anyone want anything else?

Well, if there is one thing that can be learned from selling online, it is that people are highly diverse in their opinions.  We've sold lots of Canare cables, (mostly LV-61S) and almost everyone is enthusiastically satisfied, but a few folks still wanted something more...something even better.  At first, we asked why, and even argued with them, but over time, we have come to realize that there are some of you out there who may actually be able to appreciate the difference between LV-61S and LV-77S.  One particular professional in the recording business insisted that LV-77S easily out-performed LV-61S in his setup.  He said that he could hear the difference easily.  Since then, we have offered these cables to other discriminating individuals, and they have told similar stories.  Incredible!

So, without further ado, here it is for all of you who can hear the difference -- The Incredible Canare LV-77S Precision Digital Audio Interconnect Cable.

What Makes Canare So Great?

Canare is the preference of professionals and discriminating enthusiasts, alike. You can tell, just by looking, that Canare cables and connectors are well made, and you can tell by reading the rave reviews that Canare cables are great performers!  The almost infamous Canare DigiFlex Gold cable assembly used the smaller LV-61S cable.  Over the years, it has earned such glowing reviews that one can only imagine what the reviewers will say when they try this cable!

We have found that the key to great cables is in the connectors.  Exotic conductors and shielding are fine, but it's the connectors that really make the difference.  If you want uncompromising performance, you need cables that are capable of maintaining a constant impedance.  You don't want any impedance bumps at the connectors, and you don't want the cable itself to change impedance when it bends.  Even the finest cable changes impedance a little bit when it is bent sharply, so avoid doing so.  Nice, smooth, consistent 75-Ohm impedance - that's what your equipment wants, and that's what will deliver the best performance.

You also want superior mechanical integrity.  Nice, tight connections that will not degrade over time. You want to avoid dissimilar metals, which can lead to corrosion and degrade connections.  To avoid dissimilar metals, try to stay away from soldered connections wherever you can, because solder almost guarantees that dissimilar metals will be in contact.  Good solder work minimizes the problem, but there is also the challenge of making a solder connection without heat deforming the dielectric material of the cable.  Any dimensional change in the dielectric will affect the impedance of the cable at that point.

RCA Connectors

Ironically, the most common connector used for interconnecting consumer A/V gear may also be the worst connector in general use today.  Generic RCA type audio plugs and cables have been around since the 1940s, but the old solder-type plugs typically have an impedance of about 25 ohms. As a result, they exhibit extremely poor return loss performance, even when mated to high quality cable. Some of the most expensive "high end" cables still rely on connector designs that are both electrically and mechanically inferior.

Canare's "True 75 Ohm" RCA crimp plugs solve these problems. They are impedance matched to achieve excellent performance in both digital and analog applications.  They have a usable bandwidth of over 200 MHz and VSWR is typically less than 1.1:1 from DC to 200 MHz!  This low standing wave ratio minimizes reflected signals for maximum signal transfer and clear sound.

If you look at the picture at the right, you can see the gold-plated center shaft.  If you click on the picture, you can get a better look at the internal gold-plated beryllium copper pressure fingers.  The design ensures good contact, while solving the "grip of death" problem that can be an issue with Monster and some of the other manufacturers' connectors.  (Those "grip of death" connectors put unnecessary strain on your equipment!)  Canare connectors connect up smoothly, and maintain good contact, while protecting your equipment investment.

The Cable

These Canare LV-77S cables are lightweight and more flexible than multiple shield cables from other manufacturers.  They have PVC jackets with a smooth, non-glare finish.  This is a professional, high performance, double-shielded, low loss coaxial cable.  This cable is not for everyone.  The specifications and performance are very high, to be sure -- higher than you reasonably need for digital audio applications...most folks would be completely satisfied with LV-61S, but if you want performance that goes beyond reason, this may be just the cable for you.

LV-77S is an oversized 7.7mm Canare precision coaxial cable.  It is big coax, but the stranded center conductor and braided shielding ensure excellent flexibility and long life.  The cable's compliant nature makes it easy to handle and route.

To ensure the flawless transmission of your digital signal, this high-performance cable features two layers of braided copper shielding.  This outstanding cable joins Canare's impedance matched connectors in the quest for bit-perfect digital audio.  In short, you will get the best digital sound that your system can deliver.

If you decide to compare this cable assembly to others, keep these key points in mind:

• Flexibility is desirable because it avoids stress on your equipment and on the interconnects themselves.
• Try to avoid multiple materials in the conductors or shielding, because of the problems associated with dissimilar metals.
• Low loss is desirable, but don't sacrifice mechanical integrity in favor of small differences in loss specifications!  Compared to other multiple shield cables, Canare's are very good.  Special Canare tools minimize the problems associated with consistent end terminations.
• Cables with foamed dielectric materials generally have lower loss, but foam is not without it's own inherent problems.
• Shielding is important, but don't be confused by exorbitant claims.  Electrical shielding is not the same as waterproofing -- you don't need three, four, or more layers of shielding to get good electrical shielding, and all the extra layers make the cables stiff, and tend to make good terminations more difficult to install, and more prone to failure.  As above, Canare's system goes a long way toward solving these problems.

*Our standard connectors for this cable are RCAs, but if you would prefer to have one or both ends terminated with BNC connectors, just include a note to that effect with your payment.
