That's Just How the Record Sounds

It's an error commonly made in evaluating hi-fi–system performance: the failure to listen differentially. Differential as in compared to something else. "Something else" could be a different recording on the same system or (especially this) the same recording on a different system. The question is, what are you comparing it to? The point is: Do you really know what that recording sounds like?

Re-Tales #35: Hi-Fi by the Book

Phaenelagh "Nel" Lenard Burnett is an outlier in a most basic sense: She's a woman who works in hi-fi. For the past several decades—essentially all her adult life—she has immersed herself in running her father's audio business.

Her father is John Lenard Burnett of Lenard Audio, a veteran designer, researcher, and educator whose work has crossed over from recording studios, concert halls, and commercial spaces to hi-fi for the home. The Opal 4-way active loudspeaker system is the senior Burnett's signature product and serves as the foundation of Lenard Audio's hardware and strategic designs.

"When I was a baby, Lenard was the largest manufacturer and supplier of concert PA systems and guitar amps and so on in the Australian market," Nel told me. "Some of my very first memories are of me sitting on his workbench. That was one of my happiest places to be when I was a kid, literally sitting on his work."

Revinylization #45: Charles Mingus's Changes: The Complete 1970s Atlantic Studio Recordings

The standup bass genius and jazz force of nature Charles Mingus made his first album for Atlantic Records, Pithecanthropus Erectus, in 1956. Several of his most memorable musical masterpieces, including The Clown (1957), Blues and Roots (1960), and Oh Yeah (1962), followed as he intermittently returned to the label throughout the 1960s and early '70s. Beginning in 1974 with Mingus Moves, the cigarillo-chomping, famously gruff Mingus recorded most of his final albums for the label as he progressed from composer/player to wheelchair-bound writer and musical director. His final seven studio albums for the label and a single LP of outtakes, all freshly remastered, comprise this welcome 8-LP (or 7-CD) box-set addition to the Mingus oeuvre.

Mytek Digital Brooklyn Bridge II Roon Core preamplifier

The concept of streaming digital music files over distances great (as with internet-streaming services like Spotify, Qobuz, Tidal, etc.) and small (from a home-PC hard drive, NAS, or networked music server) became mainstream only recently. But it was already brewing during the late 20th century, with people illegally downloading low-bitrate MP3 files made from CD rips and coming close to killing the recorded-music industry.

That wasn't streaming exactly, or not in the current sense, because the files needed to be downloaded, stored locally, then either played out of a computer or loaded onto a portable player, but from that point forward it was a steady march to the streaming-dominated present.

Never mind Napster—the first subscription audio "streaming" service was one you probably wouldn't think of: Audible, the audio book service now owned by Amazon, which started up in 1995. I did beta testing and editing work for early-days Audible, and around that time, I started loading up home-ripped MP3 files on a pocket-sized Rio MP3 player (which by then had replaced Audible's proprietary player), using it in place of a portable CD player. This led to experiments with a PC music library/player running Linux, controlled by a Handspring PalmOS device connected to the stereo system via a Sound Blaster 16 card.

Infigo Method-3 monoblock power amplifier

I should have trusted my ears. When I first encountered Infigo (pronounced In-FEE'-go) electronics, paired with Alta Audio's Adam loudspeaker, at T.H.E. Show 2022 in Long Beach, California, I wrote, "Timbres were beautiful on bass and high-pitched percussion. The chimes and vibes sounded special and clean, colors were plentiful, and deep bass was all of one piece." Nor was I exaggerating. In that system, Infigo's Method 3 monoblocks ($55,000/pair) pleased my ears as much as their blue-illumined interiors delighted my eyes.

Rather quickly, Editor Jim Austin suggested I review the Method 3. Perhaps he'd already been tipped off by Ken Micallef's praise when he first encountered Infigo in November 2021 at the Capital Audio Fest, and by the ensuing buzz.

Spin Doctor #4: Platter Mats, Clamps, Weights & the Timerette

The next time you're preparing to play a record, try doing a little experiment. Once you have the record mounted and spinning but before you lower the stylus into the groove, lower your gaze to just below record level and look for a gap between the platter and the record. It helps if there's a light source or a brightly colored wall behind the platter. You may discover a gap—that very little of the record's playing area is making true contact with the platter mat or (if there is no mat) the platter. Another way to test this is to take a record you don't care much about, put it on the platter, then tap with your finger in the groove area listening for a click as your finger pushes the record down and it contacts the platter surface.

Warps obviously lead to such problems, but even records that appear flat make scant contact with the supporting surface. Turntable and aftermarket accessory designers have recognized this problem for decades.
