Matching the playback stylus angle to the cutting-head stylus angle for each LP is a necessity when trying to get the absolute best sound out of your turntable system. Optimizing the VTA/SRA for each record can be a painful process of adjusting: Shimming cartridge between the headshell, shimming between the tonearm base and armboard or sliding the tonearm up and down its shaft. Doing it once during initial set up is chore enough; having to repeat the process for each record can make even the most hard-core LP enthusiast convert to digital!
All records are not created equal: the thickness as well as their weight varies.
"The Ringmat is designed to isolate the LP from the platter, to control the flow of energy created by the mechanical vibrations generated by the stylus, and to dump this energy into the air. The complete Ringmat LP Support System incorporates and optimizes the Ringmat, adds anti-static control, and allows adjustment of tonearm height by a selection of platter-placed Spacers. "
"In use, the System starts with a very thin rubber mat with a raised thumbnail-sized felt protrusion at its outside edge. Cutouts near its center area are designed to break up resonance paths. This base rubber mat is placed directly on the platter: its function is to lightly damp the platters surface and to anchor the plastic spacers, which feature a notch that fits onto the base mats felt extrusion. The 8 plastic spacers are LP-sized, color-coded by their individual thickness, and feature the same stencil-like cutouts as the base mat. By adding or removing these Spacers, the thinnest of which, colored green, is .075 mm, arm height can be altered by the finest of increments, allowing optimum SRA adjustment for each record. The thin LP Statmat, which uses conductive inks to dissipate static and to keep it from forming while the LP is spinning, is placed on top of the Spacers and under the Ringmat. The LP itself is placed on the Ringmat. Finally the label-sized Ring Cap, designed to damp any residual resonance left in the LP, is placed on top of the LP, finishing off the sandwich."
"The Ringmat Support System is an intelligent, elegantly simple solution to many of the key difficulties involved in LP playback. Static charge is eliminated and kept from forming during the process of disc spinning. The platters construction material is rendered moot by the base mat. The Ringmat damps and dissipates extraneous vibrations without the need for clamps, massive platters and the generally elephantine aspects of many popular and, in my view, ill-conceived turntables. But it is the relative ease and repeatability of setting stylus angles that is the Systems crowning touch. This is an absolutely critical adjustment for line-contact styli, but also needs to set optimally for elliptical stylus tips. The higher the resolution of the entire system, the more obvious the effects of this adjustment will be."
"The complete Ringmat System optimizes all of analogue LPs considerable musical and sonic strengths: natural and believable tonality, musically communicative phrasing, rhythmic articulation and dynamic tracking, and the ability to present a convincing stereo illusion all interlaced with the finest detail and resolution that smack of the organic rather than the ersatz and artificial. I consider the Ringmat System absolutely essential for the highest LP performance." - Paul Szabady, The Stereo Times June 2004 Click Here to read the full review in The Stereo Times of the Ringmat Support System!
