Integrated Amplifiers

Based in Treviso, Italy, Unison Research has long specialised in making very traditional looking tube amps with polished wooden chassis and rows of glowing bottles on display. At the same time its Unico series has adopted a more mainstream aesthetic and includes valve-based amplifiers that, well, don't really seem like valve amplifiers. Despite an outward appearance suggesting a completely conventional integrated amp, the Due – which sells for £2500 in standard silver with black available at a £100 premium – is very definitely a valve amp, or at least half of one.

We've been here before: ten years ago Marantz celebrated Brand Ambassador Ken Ishiwata's 30-year tenure at the company with a KI-Pearl pairing of player and amplifier [HFN Aug '09]. So its only fitting that, now he's clocked up another decade, we should have these latest KI Ruby models, limited to 1000 units apiece (500 of each in gold, 500 in black), and selling at £3500 for each unit.

Right, let’s get the ‘and fries to go’ thing out of the way first. If ever a product deserved the title, this is the ‘Big Mac’. Or at least ‘Big Mc’, for the McIntosh MA9000 is huge in every respect, from the sheer bulk of the thing – at least by the standards of most integrated amplifiers – to the 45.8kg fighting weight, increasing to 60.8kg packed, and the £12,995 price tag.

So far, Quad's Artera family has comprised the Play (a combined CD transport, DAC and preamp) and the Stereo [HFN Nov '15], which is a power amp using the company's Current Dumping topology. Both solid-state components, not only are they compact and dapper but high functioning and lifestyle literate too – a feat that's trickier than it might seem. But not as tricky as folding all of the above (plus streaming) into a chassis with the same proportions as the other components in the Artera range.

OK, so it may help explain the whole ‘vinyl revival’ thing, from portable record players with greater tracking weight than a Caterpillar bulldozer to supermarket own-brand LPs, but looking to the past will only get you so far. Forget all that longer summers, colder winters and ‘jumpers for goalposts’ stuff: even nostalgia’s not what it used to be. Products must stand on their own merits in today’s competitive market.
