Integrated Amplifiers

In the wake of well-established products such as the Sonos Amp and Bluesound’s Powernode, we’ve seen a slew of compact all-in-one amplifiers from brands including Denon, Marantz [HFN Aug ’24] and WiiM [HFN Nov ’24]. Now Chinese company Eversolo enters the fray with an offering that, while not the most affordable of its ilk, is keenly priced if you consider its extensive list of features. The Eversolo Play, at £599, even boasts a touchscreen displaying the Android-based interface also found on the brand’s DMP-A10 [HFN May ’25] and DMP-A8 [HFN May ’24] streaming DAC/preamps.

In high-end hi-fi, it’s common to see the phrase ‘two-man lift’ applied to heavyweight loudspeakers, amplifiers and subwoofers. Yet the top-of-the-line InPoL Legacy from Italian manufacturer Pathos goes one (well, two) better. This integrated amplifier, priced £51,995, arrives in a purpose-built wooden crate on wheels, along with two metal ‘pull-up’ bars that slide underneath the chassis once the crate has been disassembled. It’s then a four-person job to lift the bars and manoeuvre this 140kg beast into position.

You know where you stand with Rotel. This is a long-running company, still family-owned after almost 70 years, and with a commitment to spending money on what’s on the inside of its products rather than the cosmetics. It still winds its own transformers, and tightly specifies other components it buys in. Its halo brand, Michi, has striking looks [HFN Apr ’25 & May ’24] – from the originals with their Japanese lacquered side-panels to the understated chic of the black-on-black current generation – but the core products remain plain and simple [HFN Apr ’22], looking functional to the point where some might even consider them dour.

Swooping down into iFi Audio’s ever-expanding line-up, the £1699 iDSD Valkyrie stakes its claim as the new flagship portable. The brand typically excels at offering oodles of functionality at very reasonable prices, although the £3749 iCAN Phantom desktop headphone amp [HFN Sep ’23] shows it also has form when it comes to high-end head-fi. Nevertheless, and despite boasting a lot of familiar iFi Audio features and technologies, the iDSD Valkyrie is a very different beast – not least because it boasts a gargantuan 20,000mAh battery for extended mobile use.

The 1970s was a bumper decade for massive integrated amps and receivers although these big beasts of the audio jungle often remained something of a rarity in the UK

Big stereo receivers never made much of an impact in the UK, but this did not stop the importers servicing the large Japanese manufacturers from offering them from time to time. Pioneer, Marantz and Kenwood all boasted full-fat machines with colossal power output ratings stretching into hundreds of watts per channel – these numbers far in excess of British audiophiles’ experience. Add to this list Sansui, a brand that always had heavyweight models at the top of its ranges. The 7070 model seen here is typical of the breed – it was introduced in 1976 and remained in the catalogue until 1978.

Consumer Electronics products are traditionally marketed on the basis of progress and technological improvement, and the hi-fi scene is no exception. Amplifiers were already a mature technology in the early 1980s, following big advances in low noise circuitry, robust complementary power transistors, DC coupling and high-speed operation. With these fundamentals in place the larger manufacturers turned their attention to exotic power supplies, remote controls and system integration, equalisers and frequency spectrum displays, special inputs for CD players and, of course, ever more output power to entice customers to upgrade.

A wish fulfilled? I have already admitted in an ‘Off The Leash’ column [HFN May ’24] that, among the products I’ve never owned, I ‘lusted after’ an AirTight amplifier. So this review was accompanied by more than the usual sense of expectation, this legendary amplifier already relaunched last year as the 2024 Edition, but now officially called the ATM-1e (£8295).
