Integrated Amplifiers

With the launch of the £1300 Model 60n, Marantz finally has an entry-level alternative to the £2200 Model 40n [HFN Apr ’22]. This is par for the course, as Marantz has similar ‘good’ and ‘better’ offerings in the shape of the Model 30 [HFN Jan ’21] and Model 50 amplifiers. But where those two are ‘old-school’ analogue-only separates requiring external sources, this new Marantz amplifier is an all-in-one with DAC and streaming capabilities – all of which explains the ‘n’ for ‘network’ at the end of the name.

We've been here before: ten years ago Marantz celebrated Brand Ambassador Ken Ishiwata's 30-year tenure at the company with a KI-Pearl pairing of player and amplifier [HFN Aug '09]. So its only fitting that, now he's clocked up another decade, we should have these latest KI Ruby models, limited to 1000 units apiece (500 of each in gold, 500 in black), and selling at £3500 for each unit.

The expression 'hot on the heels' is one thing, but to launch two sets of products seemingly offering similar features at much the same price might be seen as inviting customer confusion. Yes, that's just what Marantz has done, with the SA-12SE/PM-12SE SACD player and amplifier [HFN Nov '20] followed within weeks by the arrival of the 30 Series models – yes, an SACD player and amplifier. Add in the fact that both ranges draw heavily on previous models – to put it charitably – and one might well wonder what exactly is going on.

And now for something completely different. While McIntosh has been producing big valve amps for decades and, more recently, big transistor amps – including the MA9000 [HFN Sep '18] – it is arguably better known for its use of output 'Autoformers' that manage the power into different speaker loads. Yet this diminutive £4500 MA252 actually turns out to be quite different – a compact half-width integrated amplifier with a twist. It sports a vacuum tube preamplifier section, illuminated from below, making it the company's first ever valve/transistor hybrid amplifier.

What should an audiophile demand from an integrated amplifier with a price tag approaching £15k? There's an expectation it should be beautifully built and finished and, more than likely, hail from a respected marque with a long pedigree. There must be a sense of owning something special and exclusive. The performance, meanwhile, will need to be at or near the top of what's possible at the price, and with no shortage of power. As for the new £14,995 McIntosh MA9500, and without wishing to give everything away in my opening paragraph, it looks to tick all these boxes!

Sitting in a neat stack on the desk in front of me as I write, the subjects of this review remind me of those pretty Toshiba Aurex units of yesteryear [HFN Apr '16]. There are three Micromega components in all: the Microdrive CD transport (an improbably small device, this); the Variodac, comprising a Bitstream digital-to-analogue converter with remote power volume control and an additional line input; and finally, the Microamp, a neat-looking stereo power amplifier block.
