Integrated Amplifiers

There's something comforting about a product with a singular focus, and Pass Labs' INT-25 fits that bill. A line-only integrated, it steers clear of the digital inputs, network functionality and onboard phono stage offered by many competitors. Instead, it presents itself simply as a conduit between your source(s) and speakers, combining a FET-based preamp and Class A power amp and nothing else. If that sounds somewhat 'basic', Pass Labs' history and the amplifier's £7200 price tag should suggest it's anything but. As does its mastery of music – but I'm getting ahead of myself…

Say 'Aiwa' to most audiophiles and the chances are they'll think of cassette decks. The company was one of the first in Japan to take the format seriously and later went on to lead the field, selling machines not only under its own name but as OEM products for many other brands. So why not branch out into the rest of the audio field?

So what do we have here? The new SA-12SE SACD/CD player and PM-12SE integrated amplifier, selling for £2999 apiece, are the latest in a long line of 'special edition' products from Marantz. Its family tree includes 'Original Special Edition' models, when other brands got in on the 'SE' thing, and the 'KI Signature' versions tuned by the company's late Brand Ambassador, Ken Ishiwata.

Oslo-based Hegel has been enjoying something of a purple patch of late: not content with raising eyebrows with the sheer performance of its flagship H590 integrated amplifier [HFN Oct '18], it went on to get dangerously near that level with the much more affordable H390 model [HFN Aug '19], offering almost all of big brother's sound quality for not much more than half the price. Our HFN review concluded that it was 'sensationally good value, with a clean, powerful sound and bags of musicality, not to mention exceptional flexibility including onboard network streaming'. Unsurprisingly, it won the 2019-20 EISA Award for 'Best High-End Amplifier'.

Back in 1993, Charles Hansen – the designer and founder of respected US loudspeaker specialist Avalon Acoustics – formed Ayre Acoustics. Over the 25 years that followed, he built up the brand, adding a range of innovative preamps, power amplifiers and integrated designs, all descended from the company's original 'zero-negative feedback' V-1 power amplifier. Bolstering the current lineup are various digital sources, such as the Ayre QX-5 Twenty USB/streaming DAC [HFN Dec '17], phono stages, and head-fi products like the Codex DAC/headphone preamp [HFN Jul '16] – all at prices that indicate they're not aimed at the mass market.

Phone calls from company spokespersons such as Marantz's Steve Harris, are generally one of two types. Either 'Would you like to review our new Model XYZ whatever?' or 'Where the hell is our Model XYZ whatever, which you've had for nine months?' Such phone calls are never about reviewing components that are out of production.
