select_150w_tA cure for proliferation and redundancy 

One of the downsides of assembling a state-of-the-art audio system is the proliferation of boxes for differing sources. On the digital side alone, my system has relied on three separate devices: one each for computer audio (a USB digital-to-analog converter), for SACD and CD, and for DVD and Blu-ray. Separate boxes mean multiple interconnects, power cords, and rack shelves -- an expensive proposition. Perhaps most frustrating is the knowledge that so much of what each box contains is redundant: digital filters, DAC chipsets, clocks, analog output stages. Nevertheless, no single digital device, to my knowledge, came close to providing edge-of-the-art performance with all of these disparate formats. It was therefore an exciting day last summer when Ayre Acoustics announced the imminent release of its DX-5, a new digital source component billed by Ayre as a Universal A/V Engine ($9950 USD). 

Ayre DX-5The DX-5 is a single-chassis digital player with a transport able to spin all commercially available 5" silver discs -- CD, SACD, DVD-Audio, DVD-Video, and Blu-ray -- as well as a USB input capable of receiving datastreams from the "Red Book" standard of 16-bit/44.1kHz to high-resolution files of 24/88.2, 24/96, 24/176.4, and even 24/192. My anticipation was further enhanced by reports that the DX-5 achieved higher levels of performance with audio discs than even Ayre’s own C-5xeMP (my prior reference player) -- or, with computer audio, Ayre’s QB-9 USB DAC. The QB-9 has been part of my reference system for the past 18 months, and both it and the C-5xeMP are SoundStage! Network Recommended Reference Components. As a bonus, Ayre has included video playback in the DX-5, with an attention to detail unheard of in my experience. That all of this functionality could be contained in a svelte aluminum case requiring only a single AC cord, one set of analog interconnects, and one shelf space seemed almost too good to be true. 

select_150w_tThe upward-spiraling prices of high-end-audio components over the past ten years have exasperated many audiophiles, and understandably so. How many people are actually shopping for $200,000/pair speakers? Just as frustrating, particularly for committed audiophiles who, for a single product, might well spend into the high four or even the low five figures, is just how little, these days, such considerable sums can actually buy. There’s no better example than the power-amplifier department. It’s easy to find five-grand amps made from the commonly available, off-the-shelf ICEpower modules from Bang & Olufsen. Not that these are bad per se, but the same modules are available in products that cost under two grand. What’s up with that?

Coda Technologies 15.0There was a time when $5000 or $6000 would buy a statement-type stereo amplifier -- say, a Krell KSA-250 or a Mark Levinson No.23.5. Today, used samples of those benchmark products, now almost 20 years old, still command prices of almost half of their original list prices. I wonder if, 20 years from now, today’s ICEpower amps will be doing as well.

The point is that audiophiles need to consider their purchases more carefully than ever, not only to ensure that they’re getting products they’ll enjoy listening to and that will be reliable for many years to come, but also that they’re getting something that will stand the test of time in terms of resale value. In my book, all three criteria need to be met before a product can be considered for purchase.

If you admired any of the behemoth, hot-running, sweet-sounding, solid-state amps of yore -- e.g., those Krells and Levinsons -- but missed out back then, not to worry: For those of you who, like me, have fond memories of the past but who want something fully up to date powering their speakers, there is an oasis in the desert.

Remember the old Threshold power amps? Well, Threshold is gone, and while Nelson Pass, founder of Threshold, has been producing amplifiers under his own name for some years now, other former Threshold employees are also designing and manufacturing power amps. Their company is Coda Technologies, and their amplifiers are completely up to date in terms of parts quality and circuit design, while capturing some of the all-out-assault of the hardware of years gone by.

select_150w_tSometimes a company’s very name will tell what its driving philosophy is. This is the case with LessLoss, a Lithuanian manufacturer dedicated to the preservation of as much of the audio signal as possible -- the less lost, the better. I can’t think of a better starting point. And as audio company names go, it’s refreshingly honest. They could have called themselves NoLoss -- but that’s impossible. Instead, the name LessLoss states that, “Yes, there will be damage to the original signal, but by cracky, we’re doing everything we can to minimize its impact.” 

LessLoss FirewallLessLoss made its name in the product categories of power cables and digital-to-analog conversion. I first came to know of the company when its DAC 2004 was much praised in online message boards dedicated to audio. Later, I read many good things about LessLoss AC cords, in particular the Dynamic Filtering Power Cable Signature, or DFPC Signature ($1149 USD per 2m cord). The DFPC and the Firewall do their things by employing what LessLoss describes as its own “elegant solution” for utilizing the skin effect. In a nutshell, the skin effect is the natural tendency of the higher frequencies of an audio signal to migrate toward the outer surface of a conductor. LessLoss says that its method of passive filtering takes advantage of the certainties of physics -- i.e., knowing where the high-frequency grunge is hiding -- to go about removing line noise. 

But despite those positive impressions, I soon forgot all about LessLoss. Fast-forward a few years: I caught wind that LessLoss had an entirely new product to debut, its Firewall power filter ($4686 direct, including worldwide shipping). To say that LessLoss founder Louis Motek is proud of his new baby is an understatement. With the Firewall, LessLoss thinks they’ve really hit on something. 

Premium BE"Going mono" isn’t yet an audio catchphrase, but more and more of us have taken that route for its deeply rewarding pleasures -- a sound some think superior to stereo in richness and immediacy. There’s also that vast treasury of vintage LPs that makes its way to devoted listeners via eBay, other online merchants, St. Vinnie’s and Goodwill hunting, and such bricks-and-mortar establishments as the venerated Princeton Record Exchange, Berkeley’s Amoeba Music, and the House of Records here in Eugene, Oregon. What’s more, a vibrant specialty market has sprung up, with stunning reissues of famed early rock and jazz recordings from such labels as Classic, Cisco, Music Matters, Speakers Corner, JazzWax, and Sundazed -- often pressed on heavy biscuits of 180g and 200g vinyl. My own late-night listening now is almost exclusively devoted to mono recordings.

"But what do you use for a cartridge?" The question sometimes comes up in amiable chats with fellow vinyl rats as we browse the LP bins, trying to beat each other to the next esoteric prize in its split and battered jacket. Hoping to sound truthful but not too technical, I usually say, "Oh, something kinda old-school" and leave it at that. The whole truth is, for the past few years I’ve used Ortofon’s GM Mono Mk.II -- a low-compliance, high-impedance (100 ohms internal), high-output, moving-coil SPU that comes in its own retro, G-style headshell (a 51mm distance from stylus tip to collet edge). It mounts, bayonet-style, directly on my Ortofon RS309-D tonearm, itself a 12", high-mass (with appropriate headshell), current-production model designed as a kind of throwback to vintage arms of the 1950s. Lately, though, I’ve been exploring contemporary, 0.5" MC mono cartridges of low to moderate compliance that are designed to be mounted in fixed or detachable headshells on the low- to medium-mass arms more popular among audiophiles who spin vinyl.

Magnum Dynalab MD 309To most audiophiles, Magnum Dynalab is a supplier of very high-end tuners. They certainly are that, but this Canadian company is no one-trick pony; a perusal of their website reveals not one but two integrated amplifiers in their product line. Although their MD 209 has a price ($6500 USD) much closer to those of most of the components I review, this time I went whole hog and requested a sample of Magnum Dynalab’s top-of-the-line integrated amplifier, the MD 309, which retails for a hefty $8750. 

Description 

The MD 309 is one big component. Measuring a nearly square 19"W x 6.5"H x 20"D, it’s so deep that I had to move my rack 6” farther away from the wall. It’s heavy, too, weighing 60 pounds that feels like more. Also hefty is its brick-like, full-function remote control of machined aluminum, which can also operate any of Magnum Dynalab’s many tuners. 

Three interesting aspects of the MD 309’s exterior are its 1”-thick (!) faceplate, its audiophile-spec feet, and, front and center, its 5” LCD touchscreen. Thick front panels aren’t unique in high-end components, but the MD 309’s four feet are uncommon in that the base of each one includes a Vibrapod. These are great isolation devices, and it was a treat to see that MD has put more thought into the MD 309’s feet than the industry norm of just screwing on some cones. 

Select ComponentIn the world of high-performance audio, brands come and go -- an audio firm should be considered well established only after it has survived its first decade. But given that so many hi-fi companies embody the personality of a single visionary, it’s difficult for them to survive, let alone thrive, for longer than 25 or 30 years. One venerable brand -- Audio Research Corporation (ARC), of Minneapolis, Minnesota -- has defied the odds. Founded by William Z. Johnson in 1970, ARC is now thriving in its fifth decade, even after technical and corporate leadership passed from Johnson to his protégés. ARC is devoted to the musical accuracy and integrity offered by tube-based designs; their stated goal has always been to advance the state of the art of music reproduction, and they’ve never lost sight of that goal. Yet to flourish for the better part of half a century has required more than just adherence to an ideal; also needed are sound business practices, constant evolution and innovation, a commitment of service to its customers and dealer network -- and a seemingly endless series of good-sounding, fairly priced components that stand the test of time. 

ARC Reference 5Several achievements stand out in any survey of Audio Research Corporation’s accomplishments, but perhaps it’s the series of preamplifiers bearing ARC’s “Reference” badge that loom largest. The Reference 5 line-stage preamplifier is the current torchbearer of this storied procession, and the subject of this review. 

Select ComponentRecent Western literary theory makes a distinction between the author of a book and its writer. The author is the ephemeral entity conjured as the consciousness within a given work -- a novel, say -- while its writer is the actual person who wrote it. The essential difference is that the writer has a life outside the scope of the book -- s/he eats, sleeps, messes around, plays with stereos, etc. The author resides only in the work itself, spectrally, a being conjured by the words of the text -- limited in existence, only a voice or a presence behind the words. VAC Phi 200There might be a parallel to this in hi-fi: an audio component not only has its "writer" -- the designer who goes on living life, designing other components, showing up at Consumer Electronics Shows, racing balloons in Kansas, shredding the break on the Inside Reef at Makaha -- but also its "author," the virtual voice within the machine. 

In this sense, the "writer" of the Valve Amplification Company is Kevin Hayes, president and chief designer of fine audio electronics since VAC's inception. I have met Hayes, exchanged jokes with him at audio shows, and spoken at length with him on the phone. He is definitely a personage. And yet, each VAC component has also its "author," a specific character conjured in the sound of the individual piece of gear itself, a kind of spirit in the sound. If we apply this philosophic notion of split entities to audio, it runs counter to the traditional audiophile view that identifies a particular "house sound" throughout a given line of electronics, insisting that all components produced by a company share, by design, a common character. 

Ortofon Cadenza MonoOrtofon, the venerated Danish firm that three years ago marked its 90th anniversary, has long been known for its celebrated SPU-style line of mono cartridges. These old-style, low-compliance pickup heads have a stylus radius of 25µm to play the 33.33rpm mono LPs pressed since 1948. The SPUs are made to fit "international," bayonet-mount tonearms of relatively high effective mass such as the reissue EMT 997, SME 3009 and 3012, and my Ortofon RS-309D. Their spherical styli trace the groove at a vertical tracking force (VTF) of about 3.5gm. I own an Ortofon SPU GM Mono Mk.II, which outputs 3.0mV, and I use it to play, with great satisfaction, my collection of vintage mono LPs.

Now Ortofon has introduced the Cadenza Mono ($1120 USD), a half-inch-long cartridge with a modern, nude, fine-line stylus (8x40µm) designed to track at 2.5gm. With a dynamic lateral compliance rating of 12, the Cadenza Mono outputs 0.45mV and can be used in a range of tonearms that have either fixed-mount or detachable headshells.

Select ComponentUltrasone Edition 8In the past decade, the ubiquity of the Apple iPod and other portable music players has dramatically increased the market for headphones. While the prices of these new offerings run the gamut from throwaway to four figures, most, in keeping with the emphasis on portability, tend to be earbuds or in-ear monitors -- full-size, high-quality headphones are still the province of audio engineers and a vocal minority of audiophiles. Still, headphone companies continue to release statement-level products to appeal to that niche market. One such example, the Edition 8s, from Germany's Ultrasone ($1499 USD), is the subject of this review.

Ultrasone has been designing and manufacturing headphones since the early 1990s. That makes them a relative newcomer in a product category in which most manufacturers have been in business since the early years of electronic recording. Unlike those other companies, Ultrasone makes nothing but headphones. Twenty years is more than enough time to have built a solid reputation, and Ultrasone has won numerous accolades and a devoted following of audio professionals.

select_150w_tYGA CarmelYoav Geva, founder of YG Acoustics, must have some kind of nerve. After all, he’d proudly proclaimed his flagship Anat Reference II loudspeaker “The Best Loudspeaker on Earth. Period.,” even before a single review had been published. But given the critical acclaim the Anat II would eventually achieve, he was obviously on to something. Not only did this speaker win rave reviews, its published specifications were pretty impressive. In addition to the Anat Reference II, YG’s product line has since been expanded to include the Kipod and the Carmel, reviewed here. Given the reception that YGA’s flagship model has received, the Carmel has some big shoes to fill. I can just hear the skeptics: “So, is this the third best loudspeaker on earth? Period?”

Design

Despite its appearance in YGA’s ads, the Carmel ($18,000 USD per pair) is actually quite attractive. In the ads, the speaker looks monolithic; in the flesh, it’s a sleek design in the Danish or German style that will complement contemporary and modern décors, yet won’t look out of place among more traditional furnishings. The upright upper segment contains a recessed tweeter; a 7” midrange-woofer is at the top of the much larger lower segment, with its sloped baffle. The Carmel utilizes Scan-Speak drivers, modified to YGA specifications. The tweeter, assembled in-house, is a modified 1” ring-radiator type claimed to have greatly extended frequency response, linearity, and power handling. The 7” midrange-woofer, a modified Scan-Speak Revelator, is claimed to provide clarity and bass extension in a compact enclosure.
