Review: Andrew Everard

Rotel's larger integrated amplifiers have always provided an attractive waypoint between the compact designs of hi-fi's affordable end and the monster amps of the high-end, offering plenty of power, an extensive feature-set and an entirely convincing performance. The new RA-1592MKII, selling for £2295 in black or silver finishes and claiming a 200W output, is no exception.

Polish company HEM, based just outside Warsaw in Pruszków, had something of a dream debut for its Ferrum brand: its first-ever product, the Hypsos power supply collected a 2021-22 EISA award in the Hi-Fi Accessory category [HFN Mar & Oct '21]. The judges praised it as 'a potent upgrade for a wide range of devices, not least USB DAC/headphone amplifiers, typically encouraging a sound with greater ease and smoothness – and yes, power!'

If you want an amplifier with a face, not a fascia, start saving up for a darTZeel. Designer Hervé Delétraz has a sense of humour – turning an on/off button into a 'nose' with selector/volume knobs as bulbous eyes and grinning LEDs beneath. Then there's this Swiss manufacturer's mix of golden fascias and red casework, already iconic as the brand's house style over its two decade timeline.

Some six years since the arrival of the Bowers & Wilkins 800 Series Diamond range, and over 40 years after the launch of the company's original 'no compromise' 801 model [Audio Milestones, HFN Jan '13], here we are with an all-new flagship lineup for the Worthing-based company. The timing's about right: in the rolling programme of upgrades, we've seen the 600 and 700 series replaced since the 800 D3 models broke cover [HFN Dec '15], and the company makes no secret of the fact that work started on these new 800s almost as soon as the last generation was released.
