Integrated Amplifiers

The sweet spot in a three-strong series of late '80s amps, this high current integrated promised to handle low impedance speakers without breaking a sweat. We listen...

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.

The new entry-level model in the Norwegian company's amp range is a sensible mix of facilities and performance – or at least it would be, if the sound wasn't sensational!

Oslo-based Hegel has been enjoying something of a purple patch of late: not content with raising eyebrows with the sheer performance of its flagship H590 integrated amplifier [HFN Oct '18], it went on to get dangerously near that level with the much more affordable H390 model [HFN Aug '19], offering almost all of big brother's sound quality for not much more than half the price. Our HFN review concluded that it was 'sensationally good value, with a clean, powerful sound and bags of musicality, not to mention exceptional flexibility including onboard network streaming'. Unsurprisingly, it won the 2019-20 EISA Award for 'Best High-End Amplifier'.

Korea's Citech group is ploughing its considerable in-house hardware and software resource into a series of network-attached players. Here's its most compact all-in-one

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.

Designer David Shaw has stripped the best-selling Stereo 40 tube amp back to its basics and replaced its KT88s with 6L6/KT66s for a less 'power hungry' musical experience

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.

Icon Audio's new Stereo ST30SE amplifier makes use of beefy KT150 output valves in an effort to overcome the traditionally low power of SE tube amps. Does it succeed?

The single-ended valve amplifier is still something of a niche product. Low power outputs and often equally low damping factors mean that very careful system matching, plus sensitive loudspeakers, are a prerequisite if you are to hear such designs give of their very best. However, the UK's very own guru of all things thermionic, David Shaw of Icon Audio, has decided to address these issues with his £2299 single-ended Stereo ST30SE, an integrated amp having, shall we say, a tad more welly, thanks to it being equipped with KT150 output valves.

Offering all the functionality of full-sized components, this petite five-part '90s system took micro to the max, spawning imitations industry-wide. How does it sound today?

The first time I saw a JVC UX-1 it was pictured on the side of a bus. The image was part of an ad that carried the simple message 'All features, Great, and Small'. And this turned out to be true, for the UX-1 micro system had every function imaginable, sounded like 'proper' hi-fi and was tiny.

Debate that’s been raging since the dawn of hi-fi, Integrated vs Separates boils down to this: the former’s benefits over the latter include the removal of a pre-to-power cable connection, the need for one less AC outlet, less shelf space and – above all – the knowledge that the two sections are optimised for each other. Separates, however, counter with truly dedicated power supplies for each section, as well as isolation of the pre and power amp stages for less potential for undesirable interaction. Traditionally, the higher you go up the price scale, the more likely you are to opt for separates. Over the decades, milestone integrateds would appear that upset the formula: Sugden’s A48, specific models from Rogers, McIntosh, AR, et al.
