The arrival of the Mark Levinson No.30 digital processor more than 2½ years ago marked a turning point in digital-audio reproduction. Although the No.30's $13,950 price tag put it out of reach of all but a few audiophiles, its stunning performance suggested that much more musical information was encoded on our CDs, waiting to be recovered by better digital processors. Further, it was inevitable that this level of performance would become less expensive over time. I was more excited by the No.30 than I've been over any other audio product. In fact, its musical performance was so spectacular that it alone occupied the Class A category in Stereophile's "Recommended Components."
The Mark Levinson No.30 has enjoyed a continuing residence in Class A of Stereophile's "Recommended Components" listing since it was reviewed in our February 1992 issue (Vol.15 No.2). Madrigal includes the No.30 in its "Reference" series, by which they mean that the unit will not become obsolete. Thus, when new technology became available, the No.30.5 update was introduced, consisting of a single digital-receiver printed circuit board to replace the original's three boards, and a new digital-filtering board. This revision was favorably reviewed by Stereophile in October 1994 (Vol.17 No.10).
When a manufacturer sets out to design and build a product, be it in high-end audio or any other field, the final retail price is usually a prime consideration. Parts and assembly are only part of the equation; there also must be enough buyers to amortize the design and development costs. If the product is to be a flagship modelsomething a company hopes will give a lift to its entire lineengineers will sometimes throw caution to the winds, designing a product without thought to its ultimate price, which is only set after the design is complete. When Madrigal Audio Laboratories set out to design their No.30 Reference Digital Processor, they appear to have chosen exactly this approach.
To echo Audio Cheapskate Sam Tellig, who was in turn paraphrasing Thomas R. Marshall, what the world needs is a great $299 CD player. Certainly there's no shortage of expensive units vying for your attentionmost of them consisting of separate transports and D/A converters.
Unlike the imposing mbl and Burmester DACs that I review elsewhere in this issue, the Mark Levinson No.360 is New England conservative in appearance. Its operation was simple to master despite the sophistication and flexibility on tap. Flanked by Fasolt and Fafner, the Levinson No.360 seemed as amiable as Freia.
We are now well past the era in which every review of digital playback equipment had to begin with an apology for the medium. CD replay performance may, in fact, now be bumping up against a glass ceiling. But that doesn't discourage high-end audio manufacturers from trying to advance the art, and tempt audiophiles (at least those among us who are not hopeless digiphobes) out of our minds.
It was 20 years ago that I appeared on one of the UK's equivalents of NBC's Today show to comment on the launch of CD. I wanted to talk about digital technology, but my host was more interested in the medium's lack of surface noise, which he demonstrated by showing that a disc smeared with butter and marmalade—this was breakfast television, remember—would play without skipping. (Actually, it wouldn't play; after the jammy CD was loaded, the program cut to a pretaped segment in which the player had a pristine disc inside it.)
More than a decade ago, I bought a new pair of speakers and sought to find the most suitable cables for them. After auditioning a number of borrowed sets, I enlisted my daughter to confirm my selection. She grew up in a household where there was always good music playing on good equipment, but had no active interest in either. To placate Dad, she listened to a few of her own recordings with each of the various cables and then, lo and behold, reached the same conclusion I had. In fact, she described the differences almost exactly as I would have. I was ecstatic. Not only did it confirm my opinions about the cables, but it confirmed to me that any motivated listener can hear what golden-ear audiophiles obsess about. As I tried to express my joy to her, she left the room with this parting shot: "Yes, of course, but who cares?"
MBL's Corona C15 monoblock has been one of my amplification references since I reviewed it in 2014, and as I've been reviewing DACs the past year or so, it was high time I spent time with one of the German company's digital products.
"Black shiny products are tough to photograph at shows, so trust me when I say the new N31 is dripping with gorgeousness not reflected in this photo," wrote Jon Iverson in his report from the 2017 Consumer Electronics Show. And when I unpacked my review sample of the Noble Line N31 ($15,400), I was indeed taken with its looks.
"You want to review the MDA 1000 along with the MC 275 amplifier in the same column?" Ron Cornelius, product manager and field training manager of McIntosh Laboratory, was incredulous.
There are as many ways of designing a digital-to-analog converter as there are engineers. One approach is to select parts from manufacturers' data books and build the product according to the "application notes" provided by the parts manufacturers. This is the electronic equivalent of a paint-by-numbers kit.
A more creative engineer may add a few tricks of his own to the standard brew. Bigger and better regulated power supplies, careful circuit-board layout, tweaky passive components, and attention to detail will likely make this designer's product sound better than the same basic building blocks implemented without this care. Indeed, the vast range of sonic flavors from digital processors containing very nearly the same parts attests to the designer's influence over a digital processor's sound.
Music lovers (and reviewers) long for those listening moments when their entire being lights up with joy. For me, that divine spark surfaced unexpectedly one February afternoon when, late for an appointment, I dashed into the music room, searching for my keys. That's when I heard a bit of the 24/96 WAV files of this issue's Recording of the Month, conductor Andris Nelsons's mammoth survey of the complete orchestral works of Richard Strauss, which I'd cued up on repeat to help Meitner's MA3 integrated D/A converter ($10,500) settle in.
I've been running a 5.1 system for years. Recently, I expanded it to 5.3 with the addition of two more subwoofers. This system is manageable with one of my eight-channel DACs.
Even more recently, I dipped my toe into Dolby Atmos, which made it necessary to lash up at least four more channels. That was a big problem, since neither JRiver nor Roon can support and sync more than one output device at a time, and the multichannel DACs I already owned tap out at eight channels.
I turned to the Arvus H2-4D Renderer, which offers 16 channels of digital output over AES3 and 16 channels of balanced-analog output. This worked, but piping everything through the Arvus meant forswearing DSP, including DiracLive. I really needed a DAC with at least 12 channels.
Whoever invented the adage "Good things come in small packages" wasn't into high-end audio. Most high-end products are huge and heavy, with massive power supplies, thick front panels, and battleship build quality. This dreadnought approach is justified if it directly affects the unit's sonic performance (as in the Mark Levinson No.31 transport, for example). In some products, however, the massive build can reflect a shotgun, overkill approach by the designer, or a mere fashion statement.
