GRAHAM - PHANTOM B-44 REFERENCE TONEARMGRAHAM/PHANTOM B-44 REFERENCE TONEARM Graham Phantom B-44 Gets Awarded a Golden Ear Award from The Absolute Sound! The Graham Phantom B-44 is the result of nearly two years of research into design theory, materials analysis, and extensive testing. It has exceeded our highest expectations. To come straight to the point: it has surpassed the venerable Graham 2.2 in every area of performance. The Phantom B-44 simply is in another plane of performance. “Bob Graham has been at the forefront of unipivoted am design for many a year, and this time he has got it exactly right! With the Phantom B-44, he has designed an arm whose presence I cannot hear in the highest resolution systems. The fine adjustments here really do help you zero in on optimum performances with the widest imaginable range of moving coil designs.” - Harry Pearson, The Absolute Sound, Golden Ear Award, August 2007 Technology: First, the new Graham has suppressed resonances at every conceivable point. This has been accomplished with exotic materials; for example, the Lorzig-ceramic arm tube has been refined with a slightly larger diameter that is progressionally-extruded (to resist standing waves in the tube) and precision ground. A proprietary-process glass overlay, acting as extensional damping, is applied to further suppress resonances. (As a bonus, this black glass surface provides a very fine appearance, complementing the other tonearm parts). The armtube itself, easily removable and using Grahams patented alignment system, offers the safety, convenience and accuracy of off-turntable cartridge installation and alignment, as well as allowing quick interchange of multiple pre-mounted cartridges. It is significantly improved from the earlier versions, and attaches to a nearly half-inch wide stainless-steel post-and-connector that supports the armwand under tension, resulting in virtually a one-piece armtube/pivot assembly with high damping. The connectors avoid the use of common brass as the base material; instead, they use high copper-content phosphor bronze which, in addition to being a better conductor than brass, also has less 'memory'; i.e., it won't deform as much with use, but will keep its proper tension and mechanical strength over time. The internal wiring has also been improved, with purpose-made 4-nines silver incorporating both solid and Litz construction, and with Teflon and silicone insulation jackets for fast transmission speed. Secondly, Graham has addressed the all-important (and often ignored) area of dynamic balance. Tonearms should have as little inertia as possible; yet, too often, as a result of the correct placement mass distribution being overlooked, they contribute excessive resisting forces in opposition to the requirements of the phono cartridge as it attempts to follow the ups and downs of a typical record. The Phantom B-44, in spite of its robust appearance, has been designed with a very low moment of inertia, so that the majority of phono cartridges can be used with ease and maximum performance. At the very heart of the Phantom B-44’s design is its unique ability to retrieve groove information; unprecedented in our experience. The key is a magnetic stabilization system which is the subject of patent applications, and which Bob Graham calls Magneglide™. With this unique system, all lateral stability, and a portion of the damping, is provided by powerful neodymium ('rare-earth') magnets, placed in a horizontal line from the pivot point of the tonearm. Working as an adjustable system, Magneglide™ provides, simultaneously, the following: lateral stability, azimuth adjustability, damping assist, true vertical pivoting of the stylus tip with no rotation as the arm is raised, and easily adjusted anti-skate compensation. In concert with pivot fluid damping (similar to that used with the Model 2.2), the Magneglide™ system allows normal vertical pivoting of the tonearm in true Neutral Balance, with vanishingly low friction; yet, provides a strong lateral stability that feels almost like fixed bearing arms. (No wobbling of the arm as it is lifted, for instance). |
