Wennen tries the Rudolph Bruil Record Stabilising
Ring, a go-faster goody.
vinyl collectors will be aware of the difficulty associated with the replay of
warped records; I have quite a few that are almost impossible to play! This simple
device solves the problem in one fell swoop and addresses a host of other difficulties
that turntables present.
Record Stabilizing Ring is constructed from a sandwich of materials. The top ring
is fashioned from stainless steel and is machined to fit all but the most obscure
recordings (this is due to poor quality control in the pressing plant) whilst
the middle ring is made from an acrylic substance which is sandwiched between
the top and bottom rings. The bottom ring is again manufactured from stainless
steel. I must say I am very impressed with the aesthetic quality of the product.
the wooden packing crate (thats right the crate is made from timber!) there
is an extremely extensive instruction manual, the centering disc and the RSR.
Although a little DIY is called for in the shape of attaching the timber knob
to the centering disc. This is so simple to achieve as it involves a little
glue and waiting overnight for the glue to harden. Once this has been done we
are ready to listen.
used all of the turntables that are featured in the group turntable test. They
all accepted the RSR and the clamp with one exception; this was the Roksan Xerxes.
This was due to the design of the centre spindle, as the top of the spindle has
been designed to be removed, the clamp did not grip correctly.
Bruil's RSR is simple to place on the record, first we place a record on the platter,
then we clean the record with a brush, next place the centering disc on top of
the record, and finally place the RSR over the centering disc. We now remove the
Plexiglas centering disc and place the weight or clamp over the spindle. It took
me a while to become adept with this procedure but after a while the skill base
was installed in my remaining neurones!
DOES IT DO?
RSR is intended to reduce resonance in the vinyl surface. This is achieved by
the use of a clamp in the centre of the record as well as the RSR at the periphery
of the record. Use of the RSR without a suitable clamp will result in very noisy
reproduction along with a strange stereo image presentation!
impressions were of a reduction in surface noise, which was dramatically presented
with silence on the run in grooves and also on the run out. I think this is due
to the record being clamped to the platter. After a while the differences with
the RSR in comparison to running the Bastin/Garrard 401 without the RSR were obvious.
Stereo imaging with the RSR was much larger in all dimensions. Speed stability
was measurably superior, this was evidenced by playing solo piano, solo voice
and flamenco guitar. This is due again to the record being clamped to the platter
and the extra centrifugal force as the platter with the RSR has a greater diameter
along with a larger mass.
recovery was improved a great deal, as was the overall reproduction of the vinyl.
Bass instruments were almost unbelievable in their clarity and weight. Details
in the recordings just hinted at without the RSR were displayed with subtlety.
Music I have not listened to for years was played and along with warped records
was enjoyed. Treble presentation was delivered into my living room with consummate
ease with no hint of glassy extension. Although the RSR seems rather
unwieldy, the advantages of this accessory are truly tremendous almost to the
point of being so natural that I was listening to the performance rather than
N.B the clamp in the photos is manufactured by Acoustic Solid,
although I tried the Mitchell clamp as well with very good results.
this clamping arrangement is so simple it is almost laughable. As my journeyman
said simple engineering is elegant engineering. The Rudolph Bruil
Record Stabilizing Ring is an extremely worthwhile investment and gets a thoroughly

we are still investigating the possibility of
a better production method
so more rings can be manufactured,
we still have not found a method yet as
it asks for a large investment.
However we do make a few rings for the die
