Integrated Amplifiers

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.

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.

Anyone who spends time idly clicking between websites will be familiar with the HTTP 404 error, which occurs when a browser can't find what it was looking for. Coincidentally, the Moonriver Model 404 Reference amplifier, which is priced from £4495, has a similar 'error': there may be a USB-B port on its rear panel, offering the prospect of connecting a computer to play music, but there's nothing behind it, due to circumstances beyond the control of the amp's Swedish manufacturer.
