evaporation handles the product of all
but continuous use.
While perfectly happy with the
ease of operation, I was initially less
delighted with the audible results, but
only because I had the Loricraft with
which to make direct comparisons.
Using the 12” single of
Perfect, by
Fairground Attraction (RCA PT 41846),
the VPI made the sound slightly clearer,
as if a veil had been lifted, and there
was now a larger soundstage. But,
once cleaned on the
Loricraft machine,
this recording
revealed more detail,
an even deeper
soundstage, and far
more body and
presence. Overall,
images seemed fuller
and more coherent,
and the whole
recording became
more alive and easier to
follow. Through careful
tests, on a number of
recordings, from new
pressings, which require
the removal of mould
release agents, to old,
fairly worn vinyl, I was
able to discover that there
were two major reasons for
this. Firstly, the cleaning fluids
involved in the two processes, and
secondly, the operation of brushing
the record’s surface.
VPI advise that you should
only use their own cleaning fluid, as
“others…may contain chemicals that
can damage… the machine”, but also
go on to say that “adding 25% isopropyl
alcohol to VPI fluid will give better
cleaning of dirty records”. Loricraft
recommend fluid comprising one-third
isopropyl to two-thirds distilled water.
The adding of isopropyl to VPI fluid
results in quieter backgrounds, more
detail, and a more three-dimensional
soundstage, and I now regard this
mixture as a necessity for getting the
best out of any VPI machine. However,
the use of isopropyl is frowned upon
in certain quarters, where critics claim
that it can lead to the leaching of
stabilisers from the vinyl surface and
subsequent long term damage. Whilst
this isn’t my experience, for those
concerned by the possibility Disc
Doctor fluid, a ‘two-pot’ treat and rinse
solution, offers an alcohol free
alternative which delivers excellent
results at the
expense of some
additional fuss.
The second
variation in
perform-ance
comes with fluid
application.
The VPI HW-17F’s
applicator head has a brush on its
under-side which spreads the fluid
across the surface of the disc, while
the Loricraft is manual in operation,
like the HW-16.5, and requires a,
separate, hand-held brush to do the
job. If using an independent brush
on the HW-17F, I have discovered,
much of the variances in audible
results are redressed. This can only
be a result of a lack of pressure from
the HW-17F’s applicator brush, and
I would therefore advise the use of
a separate brush when using this
machine. The brush from the HW-16.5
is readily available as a separate item.
Having worked out howto get
the best results from the 17F, lifting
its performance to the same level
as the Loricraft, there remains one
other thing to watch out for. With
the Loricraft machine, the vacuum
pickup tube rests on a small length
of cotton thread, during operation.
This is then moved approximately
5mm, onto a clean area for the next
record side. But, in the case of the
VPI, and the majority of vacuumcleaning machines, the tube is
isolated from the disc’s surface by
the same two velvet pads for every
cleaning. If you have ever seen what
is in the waste fluid produced by
these types of machines, you will
understand my concern. All cleaning
fluids start as clear liquids, but when
expelled after use, they usually
resemble murky soup, with grease and
grime floating in them. After
regular employment, this filth
and debris could be smeared
over your records. Therefore
these pads need cleaning on
a regular basis, and although VPI
recommend that they should be
“gently wiped…with a slightly
damp cloth each time you finish
using the HW-17F”, I feel that this
is not enough. A good scrub with
clean record cleaning fluid is nearer
the mark. Luckily, the tube and its
turret simply lift out of the machine
(mainly to allow them to be swapped
for an alternative tube with a shorter
slot should you want to clean 7”
or 10” records) making thorough
cleaning an easy proposition. It’s
also an essential one if you want to
maintain the cleaning performance
of the machine.
Having had an opportunity to
reflect on my experiences, I’m now in
a position to offer rather more robust
recommendations when it comes to
cleaning records, and I’ll start with
technique. Some form of vacuum
