Historically, the city of Soissons in the north of France played a major role in the First World War. But for the last 40-plus years, to hi-fi buffs it's been better known as the home base of Triangle, one of France's major loudspeaker brands. It's a company that decidedly loves to celebrate birthdays, as after launching limited Anniversary models of the Antal [HFN Sep '21] and Comète last year, it has yet another festive offering – this time a complete range encompassing four loudspeakers and two dedicated stands. Strictly speaking, Triangle was founded in 1980, which makes it nearly 43 years old. Yet with the last few years being what they were, the brand has had to wait patiently before unpacking all its anniversary cadeaux.

Musical Fidelity is no stranger to big power amplifiers. Its top-of-the-range monoblock, the £3599 M8s-700m, claims a 700W/8ohm output and weighs in at 35.5kg, and the company sells a stereo model in the M8 series too, the £3999 2x500W/8ohm-rated M8s-500s. But perhaps what few expected from the brand, considering its range also consists of DACs, streaming amps, phono stages and CD players – everything a two-channel audiophile could want, in other words – is a seven-channel amplifier. Which is what we have here, in the shape of the M6x 250.7.

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.

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.
