Audio Research’s first DAC to bear the ‘Reference’ name incorporates a network music player with access to internet radio stations, USB inputs for direct playback of files from memory sticks and HDDs, and a digital connection for iDevices. The Reference DAC is also an audiophile-grade vacuum tube preamplifier (albeit one with no analogue inputs). Its type B USB rear input socket – into which one can simply push digital data from a connected computer – provides an asynchronous interface that’s compatible with files up to ‘full HD’ 24-bit resolution and all sampling frequencies up to 192kHz. (Drivers are provided on a CD-ROM.

Lyra designer Jonathan Carr has devoted a large part of his life to developing a range of moving-coil pick-ups, and they’re expertly built by Akiko Ishiyama and Yoshinori Mishima in Tokyo. The Delos is the latest in a long line – the baby of the range it’s designed to be tonearm and phono-stage friendly: of medium weight and compliance it pushes out a claimed output of 0. 6mV at 5cm/sec. Recommended phono stage loading is from 98ohm to 806ohm (Lyra says the final value should be determined by listening).

One of the world’s most expensive, highly-developed tonearms are ‘unipivots’, though in some cases they have additional bearings: Mørchhas a dual pivot to give lateral stability, Kuzma a cunning four-point system; Continuum’s Cobra arm uses a secondary outrigger pivot mounted on its own bearing. However, it was left to Bob Grahamof Graham Engineering to come up with what is arguably the most elegant way of maximising the benefits of the unipivot concept and smoothing away its disadvantages. The breakthrough came with his ‘Magneglide’ magnetic stabiliser system – the major innovation of the first, B-44, Phantom arm. Graham lists six separate benefits for it: increased lateral stability, easy azimuth adjustment, a higher lateral inertia component for improved bass reproduction, augmentation of system damping, true vertical pivoting of the stylus with no rotation as the arm is raised, and easily adjusted anti-skate compensation.

New to the Clearaudio line-up this year, this tidy-looking Ovation model sits at the top of its group of turntables that all feature a rectangular plinth. Borrowing from the Innovation range, the Ovation nonetheless brings several new technologies of its own into play. The plinth is made of aluminium layers sandwiching a layer of Panzerholz ply. (This is is claimed to offer considerable sonic gains over such alternatives as acrylic and standard wood.
