all this stuff we had learned had basically come from the high-end hi-fi field, which we’d been trying
out over the years and discovered a lot of that stuff made a difference. Some of it was just different;
some of it was detrimental but some of it was an improvement. So we went though and we listened
to a whole bunch of XLR connectors, we listened to 20 different audio cables, because I needed 23
kilometers of cable to make our own patch bay and rewire everything in the studio… all the outboard
gear and the machinery. We listened to 20 different cables. We directionalized them all first, of
course. Every cable sounds different in a different direction. It’s small, but it sounds different. And
actually, the most amazing thing we discovered was when we listened to our technical earth cables,
which we have going into copper rods in the riverbank. Our technical earth cables are just a heavy
duty, high quality, regular, copper thick-sheathed cable. We’d been recommended to try this multi
strand thinner cable, which had been woven like some of our audio cables.
These are cables for electric?
For earthing, woven to cross individual strands at 90 degrees to each other as much as possible to
help eliminate RF etc. We listened to this, and we ran it straight out the door of the boat, over the
bridge to the copper rods and we did an A-B and listened. Even the technical earth cable, you could
clearly hear the difference from the original earth cable we were using. But even more surprisingly,
we said for a laugh, let’s just turn the cable around the other way and see if we can hear any
directional difference on the technical earth cable. And we couldn’t believe it, but we could.
What was the difference that you heard?
A difference in clarity, I suppose. One way it sounded a little middle-ier, and a little more distorted
than the other direction. Anyway, back to audio cable. We went though all these regular cables that
people wire studios up with that are fairly inexpensive. And the one that we ended up using was
made by - this is for the 23 kilometers of cabling - was made by a high end hi-fi audio manufacturer
called Van den Hul from Holland. I’d actually later found out they had originally designed this cable
for the Philips Studio in Holland. Now because they had a lot of stock on the shelf, ready to go, I was
able to negotiate a terrific deal. It only cost five times more than a regular cable would cost. But it
was worth it. It was our one chance.
I had some transformers made by Plitron in Canada, (who made the transformers for
Equitek).
For example, for the Pro Tools system the Shunyata distribution boxes have copper bus bars in them,
because it sounds better, with
thick Rhodium plating on all contacts,
I know to some people this sounds ridiculous, but I can
only say the difference is there to be heard and digital is where the biggest improvements are
noticeable.
