Integrated Amplifiers

Alot can happen in three years, and while the amplifier we have here is very much the smaller sibling of the DIA-400S [HFN Oct '16], it's also boosted by the inclusion of the Danish company's NPM module, a complete network audio solution giving access to a wide range of streaming options.

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.

Most hi-fi enthusiasts know how many watts their amplifier can produce, but does that figure tell the whole story? In the early '80s, Harman Kardon's HCC (High Current Capability) range of integrated amplifiers gave listeners another number to think about, which was how much current an amplifier was able to source.

With the H600’s streaming/DAC platform at its heart the new H400 – dubbed the ‘Streamliner’ by Hegel – looks set to take over as the sweet spot of the range

When Hegel’s reference H600 integrated amplifier [HFN Oct ’23] arrived to replace the H590 [HFN Oct ’18] last summer, it didn’t require much insight into the hi-fi industry to guess that the H390 [HFN Aug ’19] would also be marching in the general direction of the exit soon enough. It’s taken a year, though, before the replacement H400 – aka the ‘Streamliner’ – eventually pulled into port.

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!

One of the great advantages offered by network-capable audio hardware is that, once a platform has been designed, it can be rolled out across a number of products, re-purposed and scaled depending on the target market. We've seen the same from brands as diverse as AVM [HFN Dec '21], Cambridge Audio [HFN Nov '21] and Naim [HFN Aug '21], and now recent arrival HiFi Rose is following the same path with high-end players designed to be used in existing systems all the way through to one-box soundbar set-ups.

Who'd have believed that the world would be awash with affordable valve amps in the 2020s? Certainly not those who recall the desperation of trying to source fresh tubes during the era when solid-state ruled and valves were yet to make a comeback. But now the choice is so vast that you can look beyond nursing vintage Leaks or Quads, with the risks that entails. Arguably the doyen of affordable valve amps is Icon Audio, its latest the absurdly cost-effective integrated Stereo (ST) 40 MkIV 6L6, starting at £2200.
