Like the fabled rolling stone that gathers no moss, Boulder’s massive amplifiers do a fairly convincing job of rolling over any lightweight competition en route to delivering a speaker-crushing sound. Our cover stars this month are exemplars of heavyweight, component-dense, audio engineering and are about as far from the minimalist audiophile aesthetic as it’s possible to get. Not only are both pre and power amp truly balanced amplifiers–there is not a singleended RCA input or output to be found – but they adhere to the practice of using a field of (output) devices to properly manage the current demand of high power/low impedance conditions. This, and the fact that the positive and inverting sides of an electrically balanced amplifier doubles the component count, or thereabouts, goes some way to explaining the…

light fantastic

DS Audio has leveraged technologies from its £11,995 flagship Grand Master cartridge [HFN Feb’21] for its new DS-003,while targeting a more affordable price point. Utilising the brand’s now-familiar ‘optical’ platform – eschewing all magnets and coils – it replaces the outgoing DS-002 and shares the Grand Master’s redesigned independent left/right channel LED and photocell system. Improved channel separation is claimed along with an increased output – all without compromising the signal-to-noise ratio or the pick-up’s ‘musical clarity’. Aluminium is used for the DS-003’s body and cantilever, the latter married to a line-contact stylus. The internal wiring has been further thickened to lower impedance, while the weight of the shading plate (deflecting light from the LEDs) has been reduced by 50%. As with all DS Audio pick-ups, the DS-003 must be partnered with…

horns of plenty

The latest addition to Klipsch’s Heritage series is the £5100 Forte IV, a fresh update on a design the American marque first launched in 1985. This 90cm-tall ‘floorstander’ claims a 99dB sensitivity and 8ohm nominal impedance, suggesting a very easy drive for any amplifier, and uses a 380mm rear-facing passive radiator in addition to a 300mm woofer. The midrange K-702 compression driver – also used on Klipsch’s Heresy IV [HFN Nov’20] – and new titanium tweeter are mated to Tractrix horns, while a revised filter network promises a sound that’s ‘completely revoiced’ over the previous generation’s. Grain-matched wood veneer finishes are American Walnut, Natural Cherry, Black Ash or Distressed Oak. Klipsch Group, Inc., 01235 511 166; www.klipsch.com; www.henleyaudio.co.uk…

roksan refresh

New from Roksan is a four-model range it hopes will attract a ‘new audience’. The Attessa CD transport (£495), Attessa integrated (£995) and Attessa streaming amplifier (£1495) are all slim-chassis designs, in silver or black, and compatible with Roksan’s MaestroUnite control app. Meanwhile, the Attessa Turntable (£995) is available in satin white or satin black, and features a unipivot tonearm, Roksan Dana cartridge and switchable MM phono stage. Both amps use a 192kHz/24-bit Burr-Brown DAC, and claim an 80W/8ohm power output supported by a toroidal transformer-based PSU that’s derived from the brand’s costlier Caspian hardware. Analogue connections include MM phono and two line, coaxial and optical digital audio, plus Bluetooth. The Attessa streaming amplifier adds Ethernet, USB-A and integrates the BluOS hi-res multi-zone platform. Roksan, 01268 740580; www.roksan.com…

danish trickle-down

Six years after Dynaudio first introduced its Emit series, it has returned to the entry-level offering for a second-generation overhaul. There are five models in the new range – the Emit 10 and Emit 20 standmounts (£630 and £825, respectively), the Emit 30 and Emit 50 floorstanders (£1300 and £1750), plus the Emit 25C centre (£600) for multichannel systems. The speakers, which have been tuned at Dynaudio’s Jupiter measuring facility in Skanderborg, Denmark, feature trickle-down technology from the company’s Evoke series. This includes Cerotar soft dome tweeters that are in turn based on the Esotar 40 unit of Dynaudio’s Special Forty standmount. Woofer, midrange and bass/mid drivers, meanwhile, all employ a proprietary Magnesium Silicate Polymer (MSP) cone material, copper-clad aluminium voice coils and ‘dual-stacked’ magnet systems. The crossovers are a hybrid of…
