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.

Ah, the sweet spot! Positioned in the exact middle of a seven-model range of Wilson Audio floorstanders, between the Sasha DAW [HFN Mar '19] and Alexx V [HFN Jan '22], the new Alexia V – by accident or design – now occupies that most coveted of spaces. One of hi-fi's inexplicable phenomena, a 'sweet spot' seems to exist in pretty much every hi-fi model range, from turntables to amps to speakers, when a stand-out in performance relative to size and cost just happens. Yes, the new Alexia V is that special.

Nowadays there's a wealth of all-in-one units available but AVM was one of the brands to spot the trend early on. That partly explains why, even in an industry that loves extensive model ranges, the company has an impressively large product offering – including five streaming receiver solutions. And there's little concession to price in this range, so the top-of-the-line £14,950 Ovation CS 8.3 model boasts ample power reserves, a full range of streaming capabilities and a slot-loading CD player.
