Integrated Amplifiers

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.

The Chord Electronics Anni, selling for £1195, isn't the company's first compact amplifier – that honour goes to the £2900 TToby [HFN Feb '17], designed as a partner for the Hugo TT 2 DAC/pre/headphone amp [HFN Dec '15]. But the Anni is smaller, at just 16cm wide and 4.25cm tall, much lighter at 625g, and conceptually different from the TToby.

OK, OK, there are those who think 'hybrid' is a dirty word. If your glass is half-empty, it signifies compromise, or – worse – indecisiveness. If you're a cynic, then it's purely a commercial choice. But if your glass is half-full, then it's a convenient solution to various problems. As PrimaLuna has only ever made all-valve amplifiers, the company's first hybrid needs some explaining. More to the point, at £6198, the PrimaLuna EVO 300 Hybrid – clearly related to the all-tube EVO 300 [HFN Mar '21] – is its costliest product.
