iota VRS & VRS 2-Vinyl Record Stabilisers.

We have developed the iota VRS-Vinyl Record Stabiliser, this is CNC machined from billet stainless steel, and is the correct size to fit onto the recessed area of the label of a vinyl LP record. For ease of handling the top of the stabiliser has a turned “stadium” shaped handle,  with our logo. On the underside of the stabiliser it is faced with a constrained layer of carbon fibre (see *** below).

The combination of the mass of the stainless steel material and the damping effect of the constrained layer of carbon fibre act upon vibrations within the vinyl record, both from the action of the styli on the record surface as well as any structural noise derived from the turntable, the stabiliser also ensures the LP record has even contact with the platter, if that is a flat disc platter or our spindle platter.

The iota VRS Vinyl Record Stabiliser has a mass of 800 grams (1lb.12oz), this does not apply an excessive bearing load to any well engineered turntable design. For example with our standard bearing this uses a polished stainless steel shaft running in a bronze sleeve set in a substantial outer Acetal sleeve. The bearing shaft runs on a Grade 5, Silicon Nitride (Si3N4) ceramic ball, which in turn is in contact with a bottom thrust pad made from the ultra high performance PEEK polymer (Polyether ether ketone.) The bearing assembly is lubricated with a high quality fully synthetic bearing oil that also ensures a long noise free life for the bearing .

On the VRS stabiliser  the  spindle hole is formed in the combination of damping materials, polymer bonding agents, & the carbon fibre face, this combination provides a constrained layer damping effect to this surface, as its this material that is in direct contact with the record spindle and the recessed section of the record label area. This acts to provide active damping to this area, which is of course the same technique that we have adopted for the contact surface of our sub platter, directly below our Spindle Platter.

On many LP records within the label is a raised defining line, this raised boundary is pressed there as part of the manufacturing process of the LP. The VRS is designed to fit within this area, a larger diameter stabiliser would not otherwise have full and even contact with the LP surface, and would instead sit on the raised pressing line.

Using the VRS on a variety of different turntables and systems most people report the sound is better defined with more layering to the music and low frequency performance is enhanced. Within many systems we find the sound stage is increased in both depth and width, and although the overall effect on the sound is a cleaner  tonal balance, the presentation is not more bright or  forward in character.

When  the original VRS is used on other manufacturers  turntables this may require the suspension rebalancing to accommodate this additional mass, as this represents the equivalent of an additional four “audiophile” records on the suspension. However  this is well within the capabilities of most quality  suspended turntable designs that are intended to accommodate a variety of different tonearms of widely different mass .

However if suspension readjustment is  something you may be reluctant to undertake with your turntable, we have now developed the iota V-R-S-2 offering a lower mass and using a different material as an alternative that can also be used on all other manufactures turntables. The original iota V-R-S stabiliser with a mass of 800 grams (1lb.12oz) does not apply an excessive bearing load to any of our turntable designs. However we are aware that some other turntables may not have a bearing that is designed to carry the additional mass, therefore now with the alternative iota V-R-S-2 at just 240 grams ( 8.466 oz) all turntables, even suspended turnable designs may now use the V-R-S-2 without any issues or even the need to adjust the suspension to support the stabiliser.

***Constrained-layer damping is a mechanical engineering technique for suppression of vibration. Typically a viscoelastic or other damping material, is sandwiched between two sheets of stiff materials that lack sufficient damping by themselves. ….......... Wikipedia
