Welcome to the very first issue of the new Origin
Live newsletter. Thank you for signing up and for your interest.
|
It is our aim through this publication, to offer
the reader a free and regular update as to the goings on here at
Origin Live. This not only includes new product updates and reviews,
but also the opportunity to benefit from special offers and enter
into competitions.
In our experience as a long standing hi-fi
manufacturer and reseller we understand the high degree of confusion
and misunderstanding when it comes to choosing hi-fi - particularily
the age old art of vinyl replay. Sure magazines and online sources
are a help; but in an area so complex, with so many different ideas
and so much to buy anyone would be entitled to be confused. It is
our aim with the newsletter to cut through this mass of information
and offer simple, valuable advice. Each month this will include
a column article to shed some light on an often confusing and misunderstood
area of hi-fi in order to help you in your views.
This month we will be addressing the idea of under-slung counterweights,
and whether they really make any difference. Also every month we
will offer our own comments on what we feel is a class leading product.
Finally we will be running a serialized guide into one of the most
important and misunderstood areas we have come across: hi-fi setup.
This month we will begin with tonearm & cartridge setup.
We hope you enjoy the read!!

NEWS
|
As a result of continued development on the flagship Illustrious
tonearm, we have been able to dramatically improve the performance
of this arm. Consequently we have launched a special edition of
the arm known as the Illustrious Signature. |
 |
Similar in looks to the original illustrious, the
arm contains more advanced components and dramatic improvements
equating to a large leap in performance.
A good example of the true extent of the improvement is reflected
in the un-edited comments of one of our first German owners to
upgrade from the Illustrious to the Signature model.
"I can really not describe my impression. I am now engaged
in this Hobby for nearly 30 years. During that period I did have
a lot of TT, arms and cartridges. But yesterday evening the sound
was blowing me of my feet.
Rhythmic, rocking sound and tremendous midband as well as clarity in
the high signals. Very much detailed and with a soundstage that I never
did hear before. In every phase the control of the arm was overwhelming.
No fine tuning took place to now and being aware that I am anxious already
what I will achieve by doing a little fine tuning.
No doubt: This is the best arm I ever did use. In the league
of high end pivoted arms in my mind there is really nothing that
is comparable to this arm. May be it is the best arm in the world?!"
The new arm retails at 2500.00 GPB or 3495.00 USD, and are available
now.
|
 |
We have also
recently launched the Aurora Turntable, coming in at under 1000.00
GBP, it offers many of the components of the reference Resolution
turntable, including advanced subchassis design, acrylic platter
and 2 box DC power supply. The deck is also available as a package
with the world class Silver tonearm at 1470.00 GBP.
|
|
The new External DC Motor Upgrade suitable for practically all turntables
has also been so successful that we are now discontinuing the old internally
installed model. The advantages of the new model include:
· External aluminum control box for simplicity and ease of installation
· Improved transformer performance
· Improved circuit design
· Improved connections and wiring
· Option of silent running motor for an extra 39.00 GBP
|
 |
Overall this has resulted in a motor kit that is
about 20-30% up on performance and very easy to install as an upgrade
on almost all known decks .Many decks have benefited from this
superb upgrade much to the delight of their owners who did not
believe the level of improvement obtained was possible: If you
are wondering if your own deck is eligible then we have listed
decks that have been successfully upgraded as follows
Linn Lp12 Valhulla / Lingo, Michell – gyro / orbe DC,
Oracle, Pink Triangle, Rega, Well Tempered, Rock, Systemdek,
Roksan, VPI, Linn Axis, Thorens, Pro-Ject , Voyd, Alpheson Etc
(this list is not exhaustive).
The external DC Motor Kit retails for 299.00 GPB or 425.00 USD and is
available now.

COLUMN
- UNDERSLUNG COUNTERWIGHTS - AN ADVANCE?
|
Origin Live have been offering counterweight modification for
the Rega tonearm for over 10 years with much reviewer acclaim and
thousands of satisfied customers.
In recent times a number of manufactures have also introduced counterweight
and stub modifications of there own; all offering very different
theories and styling. |
|
| The obvious advantage of this is that there is a
lot of choice for people and a lot of options to try. The disadvantage,
and we have come across this a lot through enquiries and over the
newsgroups, is knowing which one works the best and gives the biggest
improvement in performance. Our opinion is that at the end of the
day theory is theory; some work and some don’t and everyone
has their own – they must be backed up by actual performance.
Audiophiles are generally not engineers and scientists. They would
rather be using the piece of equipment, which offers the best performance
rather than the best marketing brochure. It is not a coincidence
that we are the only manufacturer of tonearm modifications that
have years of quality & independent reviews to call upon and
we are one of the few offering a full money back guarantee with
our product. |
This problem is most evident with the newly advertised under
slung counterweights. The idea is that by lowering the counterweight
via an offset hole, the center of gravity of the arm is lowered
which enables the cartidge to ride the record more easily. Simply
put this is a superficially plausible idea which makes good
reading in a marketing brochure. Underslinging the weight is
of course an enormous advantage on a unipivot arm because of
stability issues in the plane which holds the cartridge vertical
and prevents it rocking or twisting. However as soon as you
move to an arm that is supported by bearings either side like
the rega and Origin Live arms then stability is not an issue.
What is an issue (especially as far as cantilever suspension
is concerned) is "inertia”; and moments of inertia
under the laws of physics tells us that the further we undersling
the counterweight the more we increase inertia which is of course
detrimental. Origin Live actually used to produce underslung
counterweights over 10 years ago when modifying Rega arms for
Avondale Audio who first produced a counterweight of identical
appearance to the Expressimo underslung counterweight long before
the acclaimed arrival of this "new" idea.
Later we tested them against non underslung weights and found
there was no significant difference in the sound at all - which
is unusual because normally the slightest change does affect
things - When the new raft of underslung counterweights came
along we revisited the whole area just in case there were something
we had missed - the results were the same - no advantage. In
fact with our design where we clamp the weight from the side
(not the top); underslinging is a disadvantage sonically. We
do not doubt that many counterweight modifications work but
it is not due to underslinging - it's down to the coupling method
of the counterweight. We would also add that although we would
claim to be the best through exhaustive testing we hope some
proper comparison reviews will be forthcoming to establish this
as it should be.
We would advise any existing owners of the Origin Live structural
mods not to accept the expressimo site claims that their counterweight
is an improvement for our arms; we have not had a single owner
tell us that this has been an 'upgrade'!

PRODUCT
REVIEW - DYNAVECTOR 10X5
|
The 10x5 is the latest release from what is now one
of the worlds leading moving coil cartridge manufacturers - Dynavector.
Much of this success can be attributed to the sheer brilliance of
the old 10X4 model, which has received unequivocal acclaim from
reviews and audiophiles alike. The new 10X5 builds on the strengths
of the 10x4, utilizing magnetic flux dampening and softened magnetism
along with a powerful neodymium magnet. The 10x5 also now features
a newly designed aluminum head block to provide a rigid platform
for the cartridge motor and secure fixing to the tonearm. |
| |
Mounting the
cartridge to the tonearm is not the easiest, however all the tools
necessary are provided and once in place it is easy to make fine
adjustments to set the alignment. The 10x5 also has a longer burn
in period than most cartridges; however this is offset by the large
increase to the cartridge life.On initial play, this cartridge reveals
little of its many talents sounding bright and rather closed in.
However after about 1-2 hours play the cartridge really springs
to life offering performance that really belies its 250.00 GPB price.
The Dynavector, unlike many other cartridges at this price point
is tonally very neutral; no added warmth like the Reson cartridges
and no extended top end like the Sumiko. Simply put this cartridge
plays back exactly what is on the vinyl.
|
The apparent neutrality of the cartridge also has
the effect of revealing the respective tonal balance of the other
components in the turntable. As such the cartridge will sound beautifully
warm and musical with for example a Nottingham deck and fast and
revealing with a Michell. As a result of this we do recommend using
a neutral arm to get best out of the cartridge. It works well with
a standard 250 or 300 arm, but is brilliant in partnership with
the modified OL1 and the Origin Live range of arms. The cartridge
is also one of the fastest you will come across; punching out the
sound with impeccable timing.
|
This has the result of offering perceptibly much
higher levels of musical separation and detail as well as the beguiling
toe taping sensation that can only really be experienced with high
quality vinyl replay. One comment that has been levied against the
dynavector range as a whole is that it is perhaps a little light
when it comes to bass extension. In practice what we have found
is that the extra levels of detail and the true neutrality of the
Dynavector means that the bass is less obvious but no less present;
and with a short period of listening the overall completeness of
the sound becomes the most obvious factor.
We at Origin Live feel that the 10X5 is a brilliant performer and
one of the best cartridges around below the 350.00 GPB price point.
A terrific match with Origin Live arms and Decks this is a true
entry to the high end.

SERIALISATION
- HOW TO MOUNT YOUR CARTRIDGE
|
As we supply most makes of hi-fi cartridge we get
asked questions from time to time about various issues regarding
set up and care. To help newcomers to this area we have produced
the following setup guide. Please note:These guidelines are of a
general nature - we publish them only to be of help and although
widely accepted they are not formally authoritative - we cannot
accept liability if you choose to use them and neither do we encourage
the time consuming occupation of answering queries surrounding the
procedures outlined - these are best referred to the manufacturer
of your specific hi-fi cartridge.
For those new or inexperienced to fitting hi-fi cartridges we would
state that this is NOT difficult and much of the detail and perfectionism
outlined below is for those who like to experiment. We ourselves
do not normally check azimuth, or vary tracking forces from the
manufacturers recommendations - neither would we worry if the arm
was up to 3mm away from the recommended distance from the spindle
- although all these details are audible they are generally of a
relatively low order, although tracking force and VTA are worth
trying should you feel anything is lacking. If things seem complicated
we would encourage you not to be put off as it all becomes clear
once you get started.
|
Importance of overall set up
Hi-Fi cartridges travel like a bobsleigh through the grooves of
a record only a few thousandths of an inch wide. You hear groove
displacements of the order of a few millionths. (That’s like
splitting a hair into one thousand pieces.) Every bit of motion
or vibration allowed at this level can be heard enormously amplified
through your speakers. For this reason it is good to set up the
turntable and arm correctly so that the audio cartridge can do it's
job properly. For instance a turntable out of level can produce
side forces on the pickup cartridge tip that will wear it more on
one side than the other as well as have a slightly degrading effect
on the wear of your records.
|
Levelness
When a turntable goes out of level, the platter bearing performance
and the arm’s dynamics, specifically anti-skate, are negatively
affected. So be sure your turntable platter and tonearm mounting
board are level - use a spirit level. If the platter is out of level,
first adjust the surface that the deck stands on. The suspension
(in the case of a suspended sub-chassis design) may also need leveling
if it has subsided over time. If the arm board is not level (which
means the arm pivot is not vertical), either return it to your dealer
for repair or re-level it yourself by shimming between the mounting
board and it’s support. |
| |
Alignment
Alignment for hi-fi cartridges needs to be optimized in three different
planes. However, it cannot be perfect in all three planes, so it
must be optimized for an overall best balance or compromise. The
final authority should always be your ears and preferably over an
extended period of listening time. Bear in mind that each record
is cut slightly differently. Here again, optimize for an overall
balance of good sound over a wide range of records. The three alignment
planes are as follows. (Please note that it is the stylus, not the
cartridge that is being aligned.)
Lateral tracking angle
Viewed from above, the hi-fi cartridges arcing movement across
the record must maintain the stylus in the same relation to the
groove
as that of the cutting stylus’s straight-line tracking;
this is Lateral Tracking Angle, or Tangency. Apart from linear
tracking
arms this is always a matter of the best compromise.
|
Azimuth
Viewed from head on, the stylus must be perpendicular in the groove
so as not to favour one groove wall, and therefore one channel,
over the other wall/channel; this is Azimuth.
Vertical tracking angle (VTA)
Viewed from the side, the stylus must sit correctly in the groove,
at the same angle as the original cutter; this is Vertical Tracking/Stylus
Rake Angle. (VTA, however, varies from record to record. Therefore,
this alignment must be set by ear, even more than is the case with
the other adjustments.) Also check that the distance from the centre
of the arm pillar (the upright post) to the spindle (usually fixed
by the arm mounting board) is correct as this will affect the ability
to achieve the tangency adjustments. This "L dimension varies
with every pivoted arm — check your manual or with the manufacturer
( in the case of Rega arms this measurement is 222mm). |
Aligning Tools
Tools required are an alignment gauge, a tracking force gauge, a
FLAT record, a screwdriver or Allen keys of the right size (usually
2mm), a good light may also be helpful. Small needle-nose pliers
and a magnifying glass all help. It also helps to have the hi-fi
news test record. Treat the arm with care as some parts are fragile.
To this end ensure that tightening of any bolts is carried out gently
and without causing undue strain. Do not adjust bearing tightness
- this is carefully set at factory - it may seem that there is slight
“play” in the bearings - this is deliberate and must
be left alone or degradation will result - it is not actually play
in the bearings but carefully designed clearance tolerances of other
components. Check hi-fi cartridge clip connections and mounting |
|
Tonearm wiring uses a standard color code for channel
and polarity ID: White = L Hot, Blue = L Ground, Red = R Hot, and
Green = R Ground. If the cartridge pins aren't color-coded the same
way, they will have letter identifications next to them. Make sure
that the arm’s wires, wire clips, and solder joints are in
very good condition. At minimum, clean the contact between cartridge
pins and wire clips by removing and replacing each clip. Holding
the clips with needle-nose pliers can make this easier, but be careful
that you don’t strain the wires where they join the clip.
Check the clips for a proper fit on the cartridge pins, and adjust
them if necessary. "Proper" means snug but not tight.
To check clip size, hold the cartridge tail-up close to the head
wires, grasp a clip firmly right behind its tubular part with the
tweezers, line it up with the cartridge pin, and press. If it does
not slide on with moderate force, the clip needs opening-up. If
it slides on easily but flops around when attached, it needs tightening.
Sizing is the operation most likely to detach a clip. The trick
is to avoid bending the wire at its attachment point or putting
too much tension on it. To avoid either, always hold the clip with
its wire slightly slack-looped behind it while adjusting. For opening
a clip, hold it firmly with the tweezers or needle-noses, right
behind its tubular section, and press the tip of the jeweler's screwdriver
into the open end of its longitudinal slot until you see this widen
very slightly. (Here's where you'll probably need the headband magnifier
or reading glasses.) You're dealing with thousandths of an inch
here, so a barely visible spreading may be all that's needed. Try
it for fit, and repeat until it does. For tightening a clip, press
a toothpick inside it as far as it will go, then use the needle-nose
pliers to gently squeeze together the sides of the clip near its
free end, while watching the slot for any change. (Attempting to
squeeze a clip without the toothpick inside it will flatten its
sides.) Try it for size, and resqueeze if necessary until the fit
is correct. When it is, close up the middle section of the tube
to match the end
Cartridge mounting screws (usually 2.5mm allen bolts) should be
tight. Steel allen bolts are the best for mounting hi-fi cartridges
- aluminum or brass are OK but difficult to tighten.
