Review: Andrew Everard

You might seem to be setting yourself up for a fall if you call your company GoldenEar Technology. It's a cue for all those jokes about effects heard only by those claiming such aural ability, grist to the mill of the 'design them properly and they all sound the same' brigade. Fortunately for the team behind the GoldenEar Triton range – including the £2300 Triton Five we have here – the product lives up to its billing, for the Five is perhaps the most striking speaker I have heard at this price level for a very long time.

They clearly don't believe in sitting on their hands at Revel as the Performa3 M106 and F208 speakers have recently been subject to wholesale revitalisation, creating the PerformaBe range, said to 'redefine performance expectations'. Comprising the £4000 M126Be standmount/bookshelf speaker and the £10,000 F228Be we have here, the new models are available in a choice of high-gloss piano black, white, American walnut or metallic silver and, while the use of ceramic-coated drivers is familiar Harman/Revel fare, the new talking point is a beryllium dome tweeter.

Based in Treviso, Italy, Unison Research has long specialised in making very traditional looking tube amps with polished wooden chassis and rows of glowing bottles on display. At the same time its Unico series has adopted a more mainstream aesthetic and includes valve-based amplifiers that, well, don't really seem like valve amplifiers. Despite an outward appearance suggesting a completely conventional integrated amp, the Due – which sells for £2500 in standard silver with black available at a £100 premium – is very definitely a valve amp, or at least half of one.

At the risk of tempting fate, I wonder whether there's a power output arms race going on between manufacturers. The arrival of the new Ultima power amplifiers from Chord Electronics – at £30,000 apiece in either silver or black, along with the matching (and similarly-priced) Ultima preamp – suggests so. After all, their rated power of 780W/8ohm load is just north of the 768W claimed by Naim's 'Statement' NAP-S1 monoblocks [HFN Jun '15] – a target vaunted as 'one horsepower'. In practice, Naim's NAP-S1 achieved 795W/8ohm in PM's lab tests at the time, but it seems that in the current ultra-high-end amp scene, there ain't no substitute for cubic inches – or something like that.
