fighting about mqa

It’s always been easy to start a fight in an audiophile bar, pretty much from back when Edison invented the phonograph (well, his version of it, but that’s a tale for another time). Back in those times, audiophiles (but they called them music-lovers back then) would argue about which needles sounded the best, the ones made of bamboo, or those made of steel. (And they did call them needles back then… the word ‘stylus’ only came along many years later.) When the phonogram was electrified, the opportunities to start fights in audiophile bars increased enormously. Direct drive vs. idler (rim) drive. Belt drive vs. direct drive. Triodes vs. pentodes. Valves vs. solid-state. Class A vs. Class AB. Class A vs. all the other amplifier Classes (Class-D, Class-H, Class G, etc). And…

rotel ra-1572 integrated

The Rotel RA-1572 integrated amplifier (with inbuilt DAC and Blue-tooth) is now available in Australia. It uses a conventional Class-AB output stage that’s rated at 120-watts per channel, both channels driven into 8 with THD of less than 0.03%. The analogue line-level input is specified as having a frequency response of 10Hz–100kHz ±0.5dB and a signal-to-noise ratio of 100dB (IHF-A) no matter whether you use the balanced (via XLR) or unbalanced (RCA) inputs. As with all Rotel amplifiers, the RA-1572 features Rotel’s custom-wound toroidal power transformers along with custom electrolytic storage capacitors made for Rotel. ‘The custom-wound transformers and power supplies are the foundation of each of their amplifiers, the source of all of the punch, clarity and headroom that these amps put out,’ said Leigh Fischer, of Interdyn, which distributes Rotel…

dynaudio sub 6

Dynaudio has released a new Sub 6 subwoofer with ‘intelligent’ digital signal processing that comes pre-programmed to integrate perfectly with main speakers from Dynaudio’s range. ‘Dynaudio’s engineers painstakingly modelled the acoustic characteristics of its most popular high-end hi-fi speakers and created custom performance maps for each one,’ said George Poutakidis, of BusiSoft, which distributes Dynaudio in Australia. ‘Using its display and the menu system built into the Sub 6, owners simply select the specific Dynaudio main speakers they have in their setup and the Sub 6’s output will be matched perfectly to it, so two-way speakers become three-ways, and three-way speakers seamlessly become four-ways.’ The DSP system in the Sub 6 is firmware-updateable, so when the company releases new speakers, Dynaudio says it will also release firmware updates for the Sub…

def tech demand series

Def Tech (Definitive Technology) has released the first three models in its new Demand Series speakers, all of which feature Def Tech’s new offset tweeter design and bass/midrange drivers that are fitted with waveguides and double surrounds. All three new models are two-driver, two-way designs. The smallest is the Def Tech D7, which marries a 114mm bass/midrange driver with a 25mm aluminium dome tweeter. A bass reflex design with a rear-facing port, it is rated with a frequency response of 67Hz to 21kHz (–3dB) and a sensitivity of 85dBSPL. It retails for $995 per pair (RRP). The Def Tech D9 pairs a 133mm bass/midrange driver with a 25mm aluminium dome tweeter. Instead of a bass reflex port, low bass response is augmented by a rear-mounted passive radiator. ‘Integrating the passive…

kef performance speaker stands

KEF has released new ‘Performance’ speaker stands that it says are ideal for use with its award-winning LS50 and LS50 wireless loudspeakers. ‘Designed and engineered in the UK by KEF’s audio experts, the Performance Speaker Stand has been built from the ground up to place bookshelf speakers at the ideal height for an optimum sound space,’ said Michael Di Meglio, of Advance Audio, which distributes KEF in Australia. ‘Available in black or white, the stands look superb and incorporate an integrated cable management system that keeps your speaker cables out of sight.’ The new KEF Performance stands are constructed from steel and aluminium and can be filled with inert filler to increase sound damping and stability. ‘Rarely does KEF introduce a speaker stand as an individual product, however with the…

mcintosh ma252 hybrid amplifier

McIntosh has released what it says is its first-ever hybrid integrated amplifier. The new McIntosh MA252 uses two 12AX7a and two 12AT7 valves in its preamplifier stage and high-power output transistors in its output stage. It is rated to deliver 100-watts per channel into 8 loads and 160-watts per channel into 4 loads. Unlike many recent amplifier designs, which feature integrated DACs, the MA252 is all-analog with two unbalanced line-level inputs, one balanced input and a phono input (MM), all of which can be adjusted for offset level to ensure consistent volume when switching from one input to another. ‘McIntosh has taken a design lead from the legendary MC275 to produce an integrated amplifier that incorporates the best of both the solid state and vacuum tube worlds,’ said Philip Sawyer, of…
