The last time we checked in, The MBL X-Treme Roadshow was in Sarasota, Florida. It has now moved on to 3mA Audio in Houston, Texas. On active display is the MBL 101 X-Treme Loudspeaker system with a full complement of Reference Line electronics: Four 9011 mono amplifiers, the 6010 D preamp, 1611 F DAC (Roon Ready), and the 1621 A CD Transport. Due to COVID-19 restrictions, for now, the MBL folks will not be in attendance. Contact Luis Miranda at 3mA Audio (832) 530-4716 or Jeremy Bryan at MBL North America (561) 725-9300 for further information.
JA gets ready for a close encounter of the Zoom kind.
"Pints With Ayre," the series of videos produced by Colorado manufacturer Ayre Acoustics, has been regular viewing chez Atkinson during these pandemic times. Covering subjects like volume control design, amplifier gain stages, audio transformers, and listening tests, the conversations between Ayre’s sales and marketing director Brent Hefley, chief engineer Ariel Brown, and CEO Ryan Berry, and special guests like Jim White of Aesthetix and Twittering Machines’ Michael Lavorgna, present sometimes esoteric technical subjects in an easy-to…
JA returned to the MBL N31 in December 2020 (Vol.43 No.12):
In Stereophile's February 2018 issue, I reviewed the MBL Noble Line N31, a baroque-styled CD player and D/A processor from German manufacturer MBL. The N31 is expensive, at $15,400, but, as I said in my review's conclusion, digital audio engineering doesn't get any better and neither does digital sound quality. However, I also wrote that the N31's absence of a volume control might be a problem for those who've sold their preamplifiers, as will be the lack of a network port for those who've banished their noisy NAS drives from the…
Herb Reichert reviewed the GoldenEar BRX in December 2020 (Vol.43 No.12):
When I first started writing for Stereophile, John Atkinson brought me a speaker to review. The shipping box was really beat, and it had some other reviewer's name on the UPS label. After a few days of trying to get it to sound good, I speculated that John and at least one other reviewer already knew this speaker did not sound good. Flummoxed, I wrote JA a simple email (he likes simple emails), "Is this a test?" He replied, "Everything is a test."
On Tuesday, at 10am, John's well-traveled, faded-tan Land…
Jim Austin reviewed the Alta Audio Alyssa in December 2020 (Vol.43 No.12):
At first look, our November 2020 review of the standmount loudspeaker ($5000/pair) from Alta Audio appeared to be a thorough vindication of the Stereophile method of reviewing, combining measurements with a subjective listening journal. John Atkinson's measurements were generally fine, but he uncovered "strong discontinuities in the impedance traces at 174Hz and 291Hz [that] imply the presence of resonances." (See fig.1 below). They could only be internal airspace resonances, since he found the Alyssa's cabinet to…
Three products are the subjects of lengthy followup reviews in the December issue of Stereophile: MBL's Noble Line N31 CD player-D/A processor, the GoldenEar BRX loudspeaker, and Alta Audio's Alyssa loudspeaker.
I very favorably reviewed the MBL N31 in February 2018—the current version is both certified as being Roon Ready and has an Ethernet network port. (The original price was $15,400; with the new network module it's $16,420.) You can find my comments on how the new N31 performed here.
I also reviewed the stand-mounted GoldenEar BRX loudspeaker ($1500/pair), this time in…
Let's begin by discussing what SAT's XD1 Record Player System is not: It is not a Technics SP-10R in a sci-fi–inspired plinth—although the XD1's engine does begin life as the SP-10R's basic drive system, which is stripped down to a handful of essential components, reimagined, reengineered, and rebuilt to much higher mechanical standards.
Marc Gomez, SAT's designer, holds a master's degree in mechanical engineering and materials science. Before dedicating himself to creating the SAT tonearm—by far the finest sounding and performing arm I've yet encountered (as unanimously corroborated by…
The platter/turntable interface is designed with a specific gap, intended to create a laminar flow for constant drag and more stable speed. A tiny, exacting gap between the platter rim and the chassis—which if you ever get to see in action is an act of machining precision few manufacturers would dare attempt—prevents air flow and exterior interference, keeping the air trapped between the platter and the chassis undisturbed.
The platter's top layer is made from a "proprietary advanced technical polymer infused with carbon-fiber micro powder and UHM carbon nanotubes," which "keeps…
In my early years of writing about audio (footnote 1), I was known—to the extent that I was known at all—as something of an objectivist. I was, after all, working as an editor at a leading science journal at the time, just a few years out from a brief career as an actual scientist, still in recovery from the physics PhD I'd earned a decade or so before.
In those days, I was more inclined to rail against obvious snake oil (footnote 2) than to defend subjective listening. I even participated in a number of spirited online debates with major industry figures, such as the late, great Charley…
