Ideon Absolute Stream Meta 2024 server/streamer

Is audio reviewing a futile pursuit? As much as we reviewers may strive, through subjective observation and objective measurement, to accurately describe how a component looks, sounds, and performs, we frequently find words and numbers inadequate to communicate the mysteries that abound in the transcendent realm of music. How can we fully share what we feel when a component allows us to experience, sometimes afresh, often in a new way, sounds that elicit joy, sorrow, terror, or more subtle emotions? How do we encapsulate in words and measurements the sonic equivalent of the wide-eyed wonder that shines through a baby's eyes as she discovers something new?

Such emotions—hence such questions—can arise when we move from one music server to another, or even between different software running on the same server. They are particularly intense in the case of this review of the Ideon Absolute Stream meta edition (2024) ($24,000) and its optional add-on, the Ideon Alpha Wave LAN Optimizer ($6900), considering that the review lacks measurements.

Burmester 218 power amplifier

As much as I tinkered with a little crystal radio as a child and started reading stereo magazines in high school, it wasn't until my early 30s that I half-stumbled into the higher end of the hi-fi sphere. As I progressed from used Advents to used Spicas and began to experiment with speaker cables, more and more names of high-end brands entered my consciousness. Burmester (founded in 1977), and some of the other higher-priced components from overseas whose looks seemed commensurate with their prices, held an outsized fascination for me. What about them, other than their visual appearance, accounted for their vaunted reputations and cost?

Bowers & Wilkins 805 D4 Signature loudspeaker

The "Bowers" in the name of British manufacturer Bowers & Wilkins (B&W) refers to founder John Bowers, whom I got to know fairly well before he passed in 1987. In recent years, I've reviewed two Bowers & Wilkins loudspeakers: the 705 Signature two-way standmount in the December 2020 issue and the Diamond Series 804 D4 three-way floorstander in the January 2022 issue. More recently, Tom Fine reviewed the three-way, floor-standing Signature Series 801 D4 in March 2024.

Currently there are two models in the Signature Series, which was launched in 2023 to pay tribute to the company's groundbreaking John Bowers Silver Signature from the early 1990s: the 801 D4 and the subject of this review, the two-way 805 D4 standmount, which B&W describes as its "highest performance standmount ever."

Analog Corner #240: Sperling-Audio L-1 turntable and TA-1 tonearm

With its swept-wing shape and platter-forward design, Sperling-Audio's L-1 turntable ($35,950, without tonearm) stands out in a crowd. This high-mass design from Germany is the result of a collaboration between Ansgar Sperling and Michael Bönninghoff, two fiftysomething engineers who began working together in recording studio construction.

Both also bring to the L-1's design and construction years of experience in signal processing. For years, Bönninghoff was the chief developer at Brauner microphones, and today is the technical director of the German pro-audio company S.E.A. Sperling worked in radio and signal processing, and has a strong interest in tubed electronics.

Piega Coax 811 Gen2 loudspeaker

It's funny how we discover some music in unexpected, twisting ways. A friend recently sent me the real estate listing for a beautiful home in Deer Isle, Maine, about an hour from where I live. I gawked at the pictures and calculated I'd need to work for Stereophile for another 127 years before I'd have enough dough to buy it. Then I noticed something unusual on one of the walls of the place: lots of gold records. Google helped me figure out that the house had belonged to the late singer-songwriter Dan Fogelberg. I knew the name but was unfamiliar with his music. Minutes later, I was playing the studio version of "Nether Lands," seemingly named after my country of birth. A beautifully orchestrated piece with restrained woodwinds and soaring strings, it reminded me of the best of Van Dyke Parks and of some post–Pet Sounds Brian Wilson songs. I played it straight through three times.

Part of the reason I was so smitten with the recording lay in the engaging, naturalistic presentation it received from the handmade-in-Switzerland Piega Gen2 811 floorstanders ($30,000/pair) that had just made their way to my listening room.

Pass Labs XP-27 phono preamplifier

One of the pleasures of reviewing—and also using—products from Pass Laboratories is an encounter with Nelson Pass's writing, which can usually be found in the owner's manual and is always competent, insightful, and sometimes funny. How often do you get real pleasure and insight from reading an owner's manual?

Pass Labs has a lot of owner's manuals online. Reading through one, I encountered the following passage; you'll find the same or similar language in other manuals and on the Pass Labs website. I present it not only because I admire it and agree with the philosophy it expresses but also because it captures the spirit of the product under review—the XP-27 phono preamplifier ($12,075 in silver)—at least as I've experienced it during an extended review period. Here it is, quoted at length with some slight adjustments to make it consistent with Stereophile's editorial style...

Dan D'Agostino Master Audio Systems Relentless line preamplifier

D'Agostino President Bill McKiegan asked if I might be interested in writing the first US review of the top-line, three-piece, fully balanced D'Agostino Relentless preamplifier ($149,500, plus $19,500 for the optional digital streaming module), which since its 2021 introduction had only received a single review, in Europe.

Me, review a $150,000 preamp? This was not a kid in a candy store–scale event. This was a kid let loose in a big-assed candy factory–scale event.

My glucose levels spiked. Questions whirled. What new virtues might a cost-no-object, presumably state-of-the-art preamplifier bring to my reference system? Would images be more corporeal? Would the soundstage be wider and deeper, tonal colors more intense? Would bass—already fabulous—be even more solid? Would the Relentless preamp move me closer to a premium-seat-in-a-live-concert experience?

Franco Serblin Accordo Goldberg loudspeaker

As founder and chief designer of Sonus Faber, Franco Serblin designed and manufactured many loudspeakers of acclaimed high quality, mainly in box form. Nevertheless, he remained painfully aware that such conventional rectangular parallelepiped constructions inevitably possessed an inherent and hard-to-suppress resonant signature characteristic of box-form cabinetry, significantly differing from that for a musical instrument. Franco had long obsessed over the sound and construction of classical string instruments, violins, violas, and cellos made by grand masters over centuries. He valued highly those richly resonant, expressive, complex sonic signatures.

Octave Audio MRE 220 SE monoblock power amplifier

Tubes, tubes, tubes—how we love to bask in their glow, roll them, and take their second-harmonic distortion into our hearts as if it were a child or a pet. Some may put out so much heat that we have no choice but to open a window, turn on the air conditioning, or listen in the garb of Adam and Eve before that fatal first bite. As they and you age, you can never be sure who's at their best. Tubes, at least, can be replaced, albeit at significant expense...

I haven't reviewed much tube gear, but when I have—Bruce Moore and VTL (in my pre-Stereophile days), Audio Research, and in our September 2022 issue, the towering Octave Jubilee Mono SE tubed pentode push-pull monoblocks—I've been enamored of their sound. I waxed ecstatic about the "captivating beauty" and "heavenly" highs of the Jubilee Mono SEs. I can still recall how gorgeous they sounded; every listen was special.

Hence, my enthusiastic "yes" to a solicitation from John Quick, VP of Sales & Marketing for Dynaudio North America, Octave's North American distributor, to review the smaller MRE 220 SE mono push-pull tube amplifier.

Vitus RI-101 Mk.II streaming integrated amplifier

Six years after Hans-Ole Vitus, the founder of Danish company Vitus Audio, visited the United States to premier his first three products at CES 2004, Michael Fremer went gaga over the company's top-line MP-P201 Masterpiece Series phono preamplifier. Thirteen years later, at AXPONA 2023, it was my turn to be blown away, this time by the sound of a $385,000 Vitus Audio top-of-the-line Masterpiece series front-end and amplifiers that sang through price-commensurate Estelon Extreme Mk II loudspeakers.

In between—and not for want of trying—Vitus's presence in these pages has been limited to show reports. It's time to change that.
