Outboard DACs

Take a quick look at the £4995 McIntosh MCD85, and you'd probably think it was another in the seemingly endless line of amplifier variations emerging from the Binghamton factory in upstate New York. In fact, the first sign that this isn't actually a power amp is the weight. Thanks to their hefty transformers and solidity of build, the company's powerhouses tend to be back-achingly heavy, and arrive on pallets – the new MA1200 integrated amp, for example, weighs in at a shade under 49kg, and the MC901 monoblock is getting on for twice that. By contrast, the MCD85 is a manageable 12.5kg boxed, and a positively featherweight 9.3kg in the buff.

In common with a lot of HFN readers, I have a bit of a 'thing' about overly complex digital devices. I'm not referring to input flexibility – many of us will have systems in which different flavours of digital connection are accommodated, from USB links from a computer to good old S/PDIF from a CD player or the like. No, what I really find obstructive is devices bristling with digital-domain options, from filters to dither to PLL bandwidth and the like, all of which often look like an exercise in 'because we can' – a facilities arms-race – rather than being of any real-world assistance to the user.

So, it's a slimline amplifier, and it's French – already thinking of the 'D' word? But while it might seem that the M-One amplifiers from Micromega could be 'inspired' by the success of Devialet's range, in fact they have little in common beyond their country of origin and a passing resemblance in dimensions: under the skin they're very different animals.

Despite persistent rumours of the standalone DAC's demise, the industry continues to provide us with converters with capabilities far in excess of any digital sources commonly available. MSB's DACs fall into this category, and given the sheer brilliance of the Premier we're reviewing here, it's hard to fathom that this isn't even the top rung of the MSB family, coming in below the flagship Select and the Reference, and above the Discrete. That said, the bare-bones version is £19,500. Ulp.

Coming from Musical Fidelity's upper-tier M6 series, the M6x is the Austrian company's priciest DAC, and the latest evolution of a product that originated around a decade ago. Of course, there has been plenty of progression through the M6 [HFN Mar '13], M6s [HFN Jan '18] and M6sR models to where we are now, both outside and in, but a few things haven't changed, including the size of the hardware, and the absence of any network streaming.
