What HFL Thinks

SME Model 30/12 Turntable - It goes without saying that the pick-up arm on your turntable is a critical part to any vinyl replay system, it does such an important job and being able to set up your arm correctly is critical to getting the maximum sound quality from the grooves of your vinyl. SME are described as makers of the best pick-up arms in the world for very good reason, these are not just tone-arms but precision pieces of engineering allowing you to set up your arm and cartridge to get the best sound possible. Offering a wide range of alternatives there is something for everyone so please come in to HFL to experience an SME arm for yourself.

The Model 30/12 is available in two formats:- 

MODEL 30/12 - £32,550
equipped for but not including SME precision pick-up arm. 

MODEL 30/12A - £35,450
with matching SME Series V~12 precision pick-up arm. 

Details:

A larger version of our well known Model 30/2, it will accept nine, ten and twelve inch arms but is especially directed at the exciting Series V-12. This offers performance 27% better than a nine inch arm in respect of angular error distortion. Its immaculate construction and finish stem from facilities and uncompromising quality control which have made the name SME a byword for engineering excellence.

Created as a companion and to compliment the Series V~12, the Model 30/12 precision turntable enjoys all of the features associated the Model 30/2 precision turntable. The differences are merely ones of scale. The suspension now provides 60 purpose moulded ‘O’ rings supporting the sub-chassis, which has been increased in thickness by some 16%, on one hundred and twenty strands of rubber. The main chassis has received similar attention but in this case the thickness has been increased by 19%. Small differences but necessary to afford the increased rigidity required to ensure acoustic neutrality.

In common with the Model 30/2, the Model 30/12 takes special account of sonic considerations and with equipment of comparable quality can provide a listening experience that allows L.P. sound to be re-assessed. Detail, resolution, and neutrality are of a new order with a dynamic range that does justice to the original sound. In conventional turntables metal supporting springs often contribute significantly to colouration. Sometimes even their size and nature can be identified by an experienced ear!

The unique suspension system of the Model 30/12, however has no sonic footprint, it hangs the sub-chassis on one hundred and twenty strands of rubber in the form of sixty purpose moulded ‘O’ rings. An ingenious method of anchorage allows them to be removed or replaced instantly, should this ever be necessary, even while a record is playing! The illustration shows how this design also places the centre of gravity where it will give natural stability with minimal sensitivity to external influences, contrasted with a conventional arrangement.

Sub-chassis motion is disciplined by four fluid dampers, one in each of the supporting columns. These eliminate overshoot and give almost zero Q recovery, allowing the user to make record and arm placements with total confidence. The isolation needed to prevent acoustic feedback is bridged by the resistive coupling of the damping fluid through which unwanted reacted energy is conducted away to ‘ground’. This function is adjustable through trimmers which can be used in conjunction with a gauge to give recommended settings or varied to suit individual conditions.

Built-in locks one at each corner of the sub-chassis, enable the suspension to be secured and automatically sealed for transport.

The moving parts of a fine turntable are of paramount importance. The spindle of the Model 30/12 is 170,5mm (6 ¾“) long and 19mm (3/4”) diameter. The massive sealed housing and individually fitted sintered bronze bearings in which the spindle runs are also of the generous proportions needed to ensure that the 330mm (13”) diameter platter weighing 7.5kg (17lb) is adequately supported. The Model 30/12’s excellent dynamics and pitch stability are largely the result of the immense care taken in the design and execution of these components.

The platter face is machined with a fine scroll found to interface better than a plain surface. A substantial reflex clamp ensures maximum contact with the platter even when severe record warp is present. The sub-chassis/arm mounting board interface is extensionally damped and the mounting board is reversible to allow mounting of nine inch pick-up arms when necessary.

The powerful electronically commutated motor is ‘cogging-effect’ free and virtually vibrationless by reason of its 2,5kg (5.5lb) weight. It is isolated on urethane mounts and adjustable for accurate belt positioning.

It can be fairly claimed that the engineering of the Model 30/12 is unique in a turntable. In the quest for perfection even the stainless steel motor pulley has received detailed attention. It is crowned to ensure belt centrality, concentric within +/- 2,5 microns (0.0001”) and secured to the precision ground tungsten steel shaft with twin grub screws to maintain rotational balance.

From this the drive is transmitted via a ground rubber belt to a 209mm (8 ¼“) sub-platter weighing 2,3kg (5lb). This is extensionally damped and incorporates four captive transit screws allowing the main spindle’s vertical thrust bearing to be off loaded for safe transport. Mains voltages available are 90-110V, 105-125V and 220-240V 50/60Hz. Please specify when ordering.

The turntable is driven by a 3 phase, brushless outrunner inductance motor with 8-pole Neodymium magnets and 3 integrated Hall position sensors. The electronic controller uses a high performance microprocessor, optimised for motor control. Closed loop speed control is implemented using a proportional plus integral (PI) algorithm. Fine pitch speed adjustment allows increments/decrements of +/-0.01% of selected speed. Speed ranges: 33.3, 45 & 78 rpm.

Complete with a comprehensive set of tools and equipment including Height Setting Gauge, Ø300mm Stroboscopic Disc, Reflex Record Clamp, Record Spindle Washer, Soft Cover and Operating Instruction Manual.

Specification:

  • Dimensions: 530 x 400 x 232mm.
  • Packing: Substantial wooden case with internal fitments.
  • Net weight with power supply: 53.5kg (118lb)
  • Shipping weight approximately: 79.5kg (175lb)

HiFi Lounge is proud to be one of a select few Bryston dealers in the UK who now come under the new Bryston Centre of Excellence initiative.

PMC speakers (Brystons UK distributer) are re-affirming their commitment to the development of Bryston for domestic use in the UK through the creation of a network of Bryston Centres of Excellence, PMC have appointed Tom Barron to the position of Bryston account manager, here is what he had to say about the new venture - account manager, here s what Tom had to say on the new venture -

"I will be working with a carefully selected group of retailers across the UK so we have strong geographical coverage that puts Bryston within easy reach of audiophiles up and down the land. Each Centre of Excellence will receive in-depth training to ensure they are fully conversant with all aspects of the brand, to enable them to serve their customers with confidence."

HiFi Lounge have been big fans of Bryston for many years now, owning much of their equipment personally before starting HiFi Lounge. We even started the always active Bryston Owners Thread on AVForums to which we contribute regularly, so it really is a privilege to be part this new scheme. We have a vast knowledge regarding the current Bryston range of which we have most on demo, so if you have any questions or would like to come in for a listen please do not hesitate to get in touch. There is nothing we like more than talking about and listening to Bryston equipment.
