Integrated Amplifiers

Few companies have been as resistant to styling changes as Audio Research. Even after a decade-plus under the ownership of fashion-conscious Italians, ARC products still suggest they belong in studios or government laboratories. Can you imagine the shock, then, when news releases arrived showing a swoopy integrated amplifier available in six colourways?

The trend for 'anniversary' products – witness the plethora of celebratory hardware on display at this year's High End show – continues with Rotel's new Diamond Series. Released to mark 60 years since the brand launched, it comprises the £3999 RA-6000 integrated amplifier and £1999 DT-6000 CD player. Not the hefty additions to the Michi lineup you might have expected, these are instead very much classic Rotel designs (fitting, as the traditionalist brand is not one to hop on every new fad that comes along) albeit with trickle-down technology from its flagship stablemates.

Say what you will about HiFi Rose, the fledgling brand hailing from Seoul in South Korea, it sure knows how to capture the attention of audiophiles. First by launching remarkable do-it-all streaming players featuring huge touchscreens and options galore, and now this 'steampunk' integrated amp which left Internet forums speechless for about 15 seconds. Quite an achievement in this day and age... and those pundits hadn't yet seen the baffling rear of the RA180 with its sixteen loudspeaker terminals!

When the Sansui AU-D33 integrated amplifier was launched in 1982, it had a lot to live up to. Its predecessor, the AU-317II from 1980 [HFN Jun '15], delivered the sort of performance one would expect from a manufacturer of specialist hi-fi, thanks to its well engineered DC-coupled circuitry. The company's 'All hi-fi, everything hi-fi' slogan set out a clear manifesto – no transistor radios, no coffee machines, just quality audio products.

The receiver (tuner/amplifier) has always divided opinion, in the UK at least. While popular in Europe and the US, the British market never embraced these units to the degree it did separate tuners and amplifiers. And this wasn't because they could not rival a two-box counterpart on performance due to any technical reason. The real issue was that two top-quality units built into one housing could result in an indivisibly expensive product, one many consumers may not have been able to afford.

So it turns out that network amplifiers built around BluOS streaming technology are like buses. No sooner had we waved goodbye to the £1299 NAD C 700 [HFN Feb '22], then up popped the Attessa Streaming Amplifier from Roksan, a little more expensive at £1495 but cut from the same just-add-speakers cloth. This joins a competitive market alongside not only NAD's device but Bluesound's £850 BluOS-based Powernode, plus other streaming integrateds including Cambridge Audio's Evo 75 and Audiolab's Omnia. Handy for Roksan, then, that it has a lot going for it.

Anyone who spends time idly clicking between websites will be familiar with the HTTP 404 error, which occurs when a browser can't find what it was looking for. Coincidentally, the Moonriver Model 404 Reference amplifier, which is priced from £4495, has a similar 'error': there may be a USB-B port on its rear panel, offering the prospect of connecting a computer to play music, but there's nothing behind it, due to circumstances beyond the control of the amp's Swedish manufacturer.
