The Iota QT Ultra-SP turntable & Satori tonearm is the flagship model in a range of four turntables all of which are designed, manufactured, and hand built here in the UK by Iota Audio Design.

The Ultra SP turntable is built to order, and the final finish options are to each individual customers preferences, from the thickness and profile of the diamond polished granite base board, to the options for fine paint, lacquer or even gold, silver, or other plated metal finish to key components used in the manufacture of this product.

The company’s Ultra SP turntable in “XL specification” offers a larger chassis and baseboard designed to accommodate multiple tonearms of any size or type, but all other aspects of its specification are the same.

The design of The Ultra SP consists of a chassis constructed from anodised extruded aluminium beams with the whole structure being internally damped and then mounted on suspension isolation towers from the high mass granite baseboard below. This ensures the ideal environment for both the iota-audio-design Satori tonearm as well as the the rotating Spindle Platter supporting the vinyl record.

The Spindle Platter on which the vinyl record is placed is made up from 26 individual components, these include a combination of 316 stainless steel high mass peripheral weights, as well as aircraft grade aluminium alloy components, plus natural cork, Acetyl turned components and advanced polymer resin bonding agents.

The aim has been to create a structure that offers high rotational mass, but to position the majority of the mass at its extreme outer edge, therefore to gain the maximum benefit of centrifugal force. In addition whilst the structure is designed so that it supports the vinyl record where it is most required at its outer edge, but also at the centre around the turntable bearing spindle. The addition of a clamp then holds the vinyl flat to this damped area at the centre of the Spindle Platter. However the area of the vinyl that contains the groove will be devoid of any platter reflections or interactions. The interface cork mat is left to do its job, and nothing else, and again as it’s not fixed and the company have alternatives available.

The supplied Satori tonearm is a suspended control point design. This employs a combination of bearing and support techniques as well as materials not previously applied or used in other tonearm designs. The combination of an exceptionally strong Pultruded carbon fibre tube of square/round section for the main arm tube, this is suspended on PVDF ( Polyvinylidene flouride) mono filaments, with the excursion of the tonearm constrained by an upward facing stainless steel control point.

As a standard option the tonearm is supplied with XLR balanced connections and so very long cable runs from the turntable can be used. However, The Iota tonearm can be supplied with standard type connector plugs at no additional charge for use in conventional systems.

The turntable is supplied with the Ultra SP power supply which acts as a mains regenerator. Frequency stability is crystal locked to +/- 30 parts per million. In fact in order to provide both 33 and 45 RPM for the two-speed model specific crystals, ground to exact specification were used. Speed change is achieved by the flick of a switch. The unit is also available for all other international mains supplies & None UK/ EU voltages.
