GOLDENEAR TRITON FIVE Our measured pink noise sensitivity for the Triton Five–averaged for the pair–is bang on GoldenEar’s specification of 90dB. Note, though, the rather different mean and music values of 91.2dB and 89.4dB, respectively, which indicate a less than flat on-axis frequency response [see Graph 1, below]. The good news is that this high sensitivity is achieved without making the Triton Five a notably difficult load to drive. Although the measured impedance minimum of 3.4ohm suggests a 4ohm nominal rating rather than GoldenEar’s ‘compatible with 8 ohms’ specification, low-frequency phase angles are sufficiently well controlled that the EPDR (equivalent peak dissipation resistance) dips to an amplifier-friendly minimum of 2.5ohm at 48Hz. Unusually, the true EPDR minimum of 1.4ohm occurs much higher in frequency at 3.35kHz, where the spectrum of typical…

sounds good?

Science Journalist Jim Lesurf has spent a lifetime in audio, both as an engineer at UK hi-fi company Armstrong and reader in Physics and Electronics at St Andrew’s University With the introduction of its Sounds app, the BBC looks like it’s making a big effort to establish itself in the ‘podcast’ arena. In itself, that’s probably a good thing. But it does make me wonder about potential unintended side effects. The most obvious aspect for an audio enthusiast is that much of the listening to audio podcasts tends to be done using mobile devices. These can be connected to a good audio system or excellent headphones, although in reality, many users won’t do either of these things. Of course, you can argue that the bulk of home FM radio listening takes place via an…

career change

After 28 years of working as a manager for the Japanese subsidiary of Texas Instruments–as well as playing and teaching guitar–VIDA’s president, Shinobu Karaki, took early retirement to make phono stages for a living. He launched Aurorasound in 2010 ‘to make my hobby my business’, adding that ‘this is what we call self-actualisation’. He says that DACs ‘cannot make people happy or make money, because of the short life cycle’. Instead, he believes that, ‘most people believe vinyl has the better sound’. The philosophy of his company is to, ‘combine good old technology with new technology to make unique products for reproducing music’. He says that the VIDA, or ‘Vinyl Disk Amplifier’, came out at the right time for the vinyl revival. ‘The VIDA Prima is for newcomers to analogue,…

AUDIOLAB 6000A Some brands are more conservative than others when it comes to specifying power output (and speaker sensitivity!) but Audiolab is flying quite close to the wire with its 50W/75W 8/4ohm rating for the 6000A. With a high 246V AC mains feed it manages 2x55W/2x85W, respectively, but we’ve seen other 50-watters achieve 70-80W/8ohm in practice. Nevertheless, the PSU is sufficiently ‘relaxed’ to support a far higher 71W and 133W into 8 and 4ohm loads under dynamic conditions, albeit with some restriction to 99W/55W into lower 2/1ohm loads [see Graph 1, below]. Otherwise, the A-wtd S/N ratio is very generous at 92dB (re. 0dBW), the output impedance usefully low at 0.01ohm and the response very extended, reaching 20Hz-20kHz (±0.1dB) and out to–1.6dB/100kHz. Distortion is also very low at ~0.0004% through the…

state of the ar-t

It is June 1982 and Compact Disc is still more science fiction than fact (although both sides have carried out their groundwork and preliminary skirmishing). The scene is the restaurant of Boston’s classy Copley Plaza Hotel and a handful of British hi-fi journalists, fresh from the Chicago CES, are dining with Ron Fone, the (English) President of Teledyne Acoustic Research. Over dessert arises the subject of turntables and the question, ‘Why doesn’t anyone–apart from Rega, or Thorens–produce a good mid-price mass-market deck?’. The answer, of course, is agreed by all present to be complex, and significant comments are made concerning the fact that all pretenders to the Linn crown end up costing in the same region. Nevertheless, the assembled hacks, fortified no doubt by the Copley’s brandy, point out to Ron…
