Phono Preamplifiers

Active/passive - not behavioural therapy, but two of Air Tight's options for cartridge amplification: the ATH-2A step-up transformer and ATE-2005 phono equaliser . With at least three turntables active in my system at any time, I’ve learned to appreciate options. All of my preferred phono amplifiers accept at least two decks and can cope with both MM and MC cartridges of varying output levels.

It’s been almost two years since Hi-Fi News had the pleasure of auditioning a CD player and integrated amplifier from the Italian Audia company [see HFN September 2007]. With just a select range of amplifiers and a couple of CD players in its product portfolio, Audia may barely register as a blip on the radar of British audiophiles. On the European specialist audio scene, on the other hand, Audia has carved out a name for itself as a manufacturer to be taken most seriously in the high-end arena, its products regularly garnering accolades in French and German magazines as well as on its home turf in Italy, naturally. Talking of carving out a name, you just know that Audia’s products aren’t going to come without a fairly substantial price ticket attached to them when you see the build quality.

Fans of the brand know that when Audio Research adds an 'SE' suffix, the changes go beyond the cosmetic. The latest to earn this upgrade is the Reference Phono 3

Let's talk about names. Audio Research's abiding Reference range has long been subject to shorthand – even the factory calls the models 'REF' for brevity – while updated (mk2) components are now defined by 'SE'. And that now applies to the £17,500 Reference Phono 3SE. In this case the revisions are retrofittable and, at £3500 and given my delight with every SE model I've tried, especially with the REF 6 and REF 75, I suspect most existing owners will want the upgrade. My optimism was fuelled by Audio Research's CEO Dave Gordon who told us, 'The SE changes incorporated in both the REF 6 and the REF Phono 3 are almost identical, involving many of the same passive component upgrades'.

Aurorasound's VIDA (Vinyl Disk Amplifier), launched in 2011, has marked its first decade with a number of revisions to merit MkII status. How does it stack up in 2022?

Small Japanese specialist brands always fascinate me, due in part to my delight that they can co-exist with the Sony- and Panasonic-sized manufacturers. While every nation has its bijou marques, there's an uncanny aura to the likes of 47Lab, Shindo, Air Tight and Kondo, plus countless MC cartridge makers, that differentiates them from equally exotic producers from the UK, USA, Italy, Germany and beyond. Aurorasound could also only be Japanese, its VIDA MkII, an evolution of the VIDA [HFN Jul '13], ticking every box.

When someone as determined and perfectionist as Conrad Mas of Avid decides to enter a new product area, the result is likely to be something special. With the Pulsare Phono, the aim was to produce a phono stage that could do the same things for music that an Avid turntable did. It had to have ‘that certain something that makes the music sound and feel real. ’ Even a first glance tells you that this an overkill design in specification, construction and features.

The inaugural product in Colorado-based Boulder's 500 series is this MM/MC phono preamp – fully balanced throughout, including the connection to your turntable

Modern phono stages seem to fall into one of two camps – those with multiple inputs, multiple gain options and a seemingly endless permutation of impedance and capacitance settings [see EAT E-Glo S, HFN Mar '17], and those, like the Boulder 508, that seek to minimise switching and variable gain in favour of one, potentially simpler, signal path.
