Integrated Amplifiers

How much power does your present amplifier produce? Expectations have risen over the years to the point that wattages in the three-figure range are no longer exceptional. But is this necessary? The Philips AG9016 seen here is rated at 2W per channel – not even sufficient to satisfy the fairly lax requirements of the DIN 45 500 'hi-fi' standard, which requires six watts.

Having recently achieved the grand old age of 80 years, the Pioneer Corporation is rightly celebrating the fact. While some believe that all Japanese companies are the same – faceless consumer electronics giants with sprawling factories full of robots, making generic white goods – anyone who's lived in Japan knows this couldn't be further from the truth. In practice, each organisation has its distinct identity and corporate culture, going about things in its own special way.

It's important to accept how language evolves, particularly when reviewing an amplifier with a name that is a contraction of 'evolution'. PrimaLuna calls its current lineup EVO, as it represents the next step in the advancement of its valve amps, and the 40W-rated £3798 EVO 300 integrated represents the mid-point in a 13-model range.

With its two Wi-Fi aerials protruding from behind, allied to the skinny front control knobs, swish brushed aluminium fascia and three 'podular' feet, there's something very Jetsons about the look of the Primare I35 Prisma network-ready amplifier. It has the appearance – perhaps unintentionally – of a cutting-edge piece of technology from the late 1950s, a time of dramatic change as the world entered the Space Age.

Mini hi-fi, very much 'a thing' in the 1980s, is still breathing today thanks to Heinz Lichtenegger's Pro-Ject brand. 'Small is better', according to Pro-Ject's head honcho, stating that modern music lovers want great sound without bulky hi-fi gear. Surprisingly, the MaiA DS3 integrated amplifier tested here is one of the larger of Pro-Ject's 'Boxes', being part of its DS line which, together with the RS line, trades some compactness for improved electronics. The company's budget E and more accomplished S series are the home of truly diminutive devices.

PS Audio’s new Stellar Strata MK2 amplifier looks – at first glance – identical to the original Stellar Strata [HFN Mar ’21], save the ‘MK2’ lettering now added to its fascia. The slender chassis, offered in silver or black and a feature of all Stellar series hardware, is retained, as is the slim text display, right-side volume rotary and headphone output of its predecessor. So from the off, it’s clear that any changes made for this second-generation design are under the hood.
