Review and Lab: Paul Miller

Here's a fun game to play: look through the product catalogue of US manufacturer Balanced Audio Technology and try to spot the odd one out. It should only take you a matter of seconds because all of its current models, bar one, employ tubes in either their power or preamp stages. And if you still haven't realised I'm talking about the new REX 500 power amplifier, it's the one that's roughly twice as big as all the others.

At times of late, it seems Salisbury's Naim Audio is wilfully courting controversy. It's been causing ripples with the brand's faithful fans ever since it launched its all-in-one Mu-so systems and second-generation Uniti products. It wasn't that these arrivals were on a mission to make hi-fi simpler for all, eschewing the tweakery and 'black magic' once suggested as a prerequisite for realising its true potential – no, what broke the usually calm surface was the fact the Naim logo, for decades lit in green, had turned white. Cue Naim aficionados fanning themselves like Edwardian grandes dames with a fit of the vapours.

It's too easy to presume, just because only one change separates a new model from an earlier one, that assessing it will be a breeze. DS Audio's £18,995 Grand Master Extreme optical cartridge differs from its stablemate solely in its cantilever/stylus assembly. Aside from a different body colour for easier identification, I wrongly imagined that a side-by-side shoot-out with the earlier Grand Master [HFN Feb '21] would suffice, and that a couple of LPs' worth of listening would reveal all. Silly me.

Was it really 25 years ago that QED celebrated its Silver Anniversary with a special edition XT speaker cable? Or a full half century since the brand burst into our audiophile consciousness with, three years later, what must surely be the most famous cable of all time – QED 79-strand? Monster Cable would surely argue the toss, but for hi-fi fans building their first system on a budget, the classic figure-of-eight 79-strand (still only £1.99/m) has long been the go-to choice.
