The sound of the Abis SA-1.2 tonearm is quite unique, due to its substantial design and construction, the main arm component is engineered from one billet of aluminum, and assembled with great precision and care. There is virtually none of the resonance associated with S-shaped arms and far more strength plus lower 'critical' resonances than virtually all straight arms.
The weakness of low mass tonearms is that they make poor matches for medium and low compliance cartridges. The Abis SA-1.2 gives you precise radial-bearing performance and very low resonance, while providing the necessary mass for medium and low compliance cartridges.
A major influence in the performance of the SA-1.2 (Silver anodised) and SA-1.2B (black anodised) is the use of very high quality bearings. The bearings used for horizontal movement are axial-loaded (angular-contact) thrust-bearings. These thrust bearings have zero play and are held in contact by gravity - think of them as acting like a unipivot, but with more than one contact point. Because of their design with two tapered seats, they self-align in the presence of a load (gravity) and have exceedingly low friction.
In contrast to classic tonearms from the past (which suffered from resonance and lower quality bearings), the SA-1.2 provides the ideal mass for classic cartridges like the Denon DL103 or Ortofon SPU (also, mono cartridges like the DL102, or even antique cartridges like the GE VR and Fairchild) as well as most moving coil cartridges.
The Abis SA-1.2 arm has very low tracking error, the superior sonic signature of the billet aluminum arm parts, and the mass equivalent to most 12″ arms, offers a 12″ arm sound in a compact 10" arm length. A protractor is supplied to ensure an optimum geometry for Rock and Pop records, but can be altered (simply) to suit classical records better if required. It is ideally suited for low to medium compliance cartridges, especially good at controlling problematic cartridges when it comes to miss-tracking, such as the older 'classic' designs.
How does the Abis sound? It has superb tone and timing, with a 'liquid' mid range to match the very best tonearms. Bass is tight and integrated with the whole, top end is clean and precise. The Abis SA-1.2 and SA-1.2B offer exceptional value for money, will work well with most cartridges, particularly Moving Coil types, getting the best out of them.
