Integrated Amplifiers

The Denon duo in the limelight here are an obvious refresh of the previous generation DCD-1600NE disc player and PMA-1600NE amp, introduced in 2017, rather than entirely new designs. Partly that's because both the £1299 DCD-1700NE and £1699 PMA-1700NE look very similar, if not identical, to their predecessors. The solid construction, metal front fascia that curves to ensure the Denon logo catches the light, the weighty volume knob in the middle of the amp, the old-school tone controls… it's all very par for the course, as is the choice between black or silver colourways.

Mini hi-fi, very much 'a thing' in the 1980s, is still breathing today thanks to Heinz Lichtenegger's Pro-Ject brand. 'Small is better', according to Pro-Ject's head honcho, stating that modern music lovers want great sound without bulky hi-fi gear. Surprisingly, the MaiA DS3 integrated amplifier tested here is one of the larger of Pro-Ject's 'Boxes', being part of its DS line which, together with the RS line, trades some compactness for improved electronics. The company's budget E and more accomplished S series are the home of truly diminutive devices.

The Boulder story begins in 1984, with the release of the 500 Power Amplifier. A professional audio company back then, Boulder's stereo model was destined for music studios and broadcast suites, but founder Jeff Nelson soon realised the hardware had domestic potential too, resulting in the 500AE 'audiophile edition'. Today, nearly 40 years and an expanded product portfolio later, the Colorado-based manufacturer remains a darling of the high-end hi-fi scene, albeit one whose designs still have a 'pro audio' air about them.

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.
