Integrated Amplifiers

These days, the letter 'i' included in a product name will have some people assuming there are networking features onboard – blame BBC iPlayer or Apple iTunes, I suppose. It's therefore worth stressing that Simaudio's £1900 MOON 250i is an all-analogue integrated amplifier (that's what the 'i' stands for here, of course), lacking digital connectivity and DAC, or any networking talents whatsoever. If this counts as an old-school approach, then there's at least one good reason for it – the 250i has now been in the Canadian company's stable for a decade.

Another smart move from the Korean tech specialist? That certainly seems to be the case with the latest arrival from Seoul-based HiFi Rose, which has rapidly established itself as a major player in the network audio/video market with a string of excellent streaming players. Having taken what looked like an abrupt turn with the launch of its bonkers-styled – but great-sounding – RA180 integrated amplifier [HFN Jul '22], it's now delivering on the promises made by the company's Sean Kim, interviewed for that review. We're yet to see the simpler, more affordable RA280 integrated amp, but here's the company's all-in-one streaming amp, the RS520.

Almost all audio enthusiasts will know Goodmans for its range of loudspeakers. However, the company's other hi-fi products are less well remembered, despite the fact that more than one or two achieved considerable popularity among buyers.

How much power does your present amplifier produce? Expectations have risen over the years to the point that wattages in the three-figure range are no longer exceptional. But is this necessary? The Philips AG9016 seen here is rated at 2W per channel – not even sufficient to satisfy the fairly lax requirements of the DIN 45 500 'hi-fi' standard, which requires six watts.

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!
