up radio-frequency noise and feeding

it into the system through the ground,

and it also prevents certain components,

particularly digital components, from

radiating digital noise where it can get

into places it shouldn’t. Though some

power cables have price tags that can

induce cardiac arrest (another reason

they use hospital grade connectors,

perhaps), some affordable ones offer both

shielding and good connectors.

Shielded power cables, by the way,

have generally more capacitance than

the cheap cables that no doubt came

with your gear, and that is already

enough to ﬁlter out a little of the high

frequency hash that comes from the

power company. To ﬁnish the job it’s

useful to add a good power ﬁlter, but as

you already know good ones don’t come

cheap. Some of them, what’s more, can

actually make your system sound worse,

hence the warning from some experts. In

particular, ﬁlters that limit current can

adversely affect power ampliﬁers.

And we haven’t yet gotten to the

speaker cables and interconnects. If

you’re using the cheap junk that is avail-

able free or almost free, then changing

it is virtually an emergency measure.

I have just completed the removal of

the Valhalla board, AC motor, switch and

associated cables on a Linn LP12 turntable

and replaced them with the Origin Live

Advanced DC motor kit. The results are

nothing short of impressive and seem (by your

description) to be very similar in character to

the improvements realized with the Lingo

I was wondering if you had ever heard

the mod, and how it compares to the Lingo.

I’m sure Linn is not in favor of this type

of behavior but I would guess some UHF

subscribers (like me) wouldn’t mind seeing a

comparison of the available PSU options that

can drive the LP12. Considering the cost of

Lingo upgrades, these alternative mods start

to look pretty good.

Nick, many years ago we did a direct

comparison between a stock Linn LP-12

and an LP-12 that had been upgraded

with a subchassis made from a more

exotic material. The one with the new

subchassis sounded better. Now here’s

where it gets interesting. One of our then

staff members, Henry See, was looking

for a good turntable, and he was offered

either of the Linns at the same price.

Despite the fact he had participated

in the comparison, he chose the stock

Linn.

Now why would he do that? He

explained the reason for his choice:

the upgraded LP-12 did sound audibly

better, but it wasn’t a Linn anymore.

There was reason to believe that Linn

would be offering more upgrades in the

future — indeed it already was — but if

Henry bought the modiﬁed LP-12 none

of those upgrades would ever be avail-

able to him. In retrospect he was right.

Today’s Linns, even those that have not

had the full tilt upgrades, sound way

better than the modded LP-12 Henry

turned down.

To be sure, what was true then may

or may not be true in 2006. Linn’s turn-

table sales are today a tiny fraction of its

business, and it isn’t certain that future

upgrades will amount to more than

tinkering. A third party improvement
