Integrated Amplifiers

For a brand name that appears on very diverse products, from grand pianos to outboard motors, it’s amazing that Yamaha has little in the way of high-end head-fi – the company was a very early adopter of planar-magnetic headphone technology, after all. The HA-L7A DAC/headphone amp is the second product launched to address that deficiency, following on from the YH-5000SE headphone, which garnered an EISA Award last year and is a spiritual successor to the legendary HP-1 from ’76.

If I had a pound for every time I’d heard someone talking about WiiM in the last year I would easily be able to afford the £329 streaming amplifier auditioned here. Since its arrival in the UK in 2023, WiiM – the consumer-facing brand of California-based smart technology company Linkplay – has earned a reputation for compact, networked hi-fi products that combine wide feature sets and a forward-thinking control app, but at prices that would have seemed like science-fiction just a few years ago.

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.

The Wharfedale Linton loudspeaker is one of those hi-fi products that seems to have been around forever. It has been produced in many forms and is still with us today in ‘Heritage’ guise. The original Linton, Super Linton and Linton 2 were all strong sellers in the 1960s and ’70s and many listeners will have heard, owned or borrowed a pair at some stage. Lesser known was Wharfedale’s complete Linton system, which was offered in hi-fi’s boom years of the early 1970s. It is the amplifier from the first version of this which we are looking at this month.

HiFi Rose delighted, and in some cases flabbergasted, hi-fi enthusiasts with its RA180 [HFN Jul '22], an amplifier that looked like it had just escaped from the pages of Gibson-Sterling's steampunk classic The Difference Engine. Boasting lots of knobs and dials on the outside, and novel GaN FETs in its Class D power amp on the inside, it was undeniably 'something else'. It was quite an unexpected product from the Seoul-based brand too, as up to that point HiFi Rose was principally known for streamers and DACs with very large touchscreens [HFN Jun '21 and Mar '22].

Now that Heinz Lichtenegger, president of parent brand Audio Tuning, is comfortably behind the wheel of Musical Fidelity and the marque is churning out a steady flow of new products, including the rather notable Nu-Vista amplifiers [HFN Mar & Aug '23], it's good to see the full history of this British brand being revisited. The £1499 reissue of the 'griddle plate' A1 integrated amplifier is a case in point. Without losing sight of the past – or the original A1's flaws – it has been reworked by Simon Quarry, the engineer in charge of most new Musical Fidelity designs. The result is a fully symmetrical, Class A-biased amplifier that looks, and sounds, true to the original – it is not simply a vintage lookalike with unconvincing innards.
