Audio Research's Making The Music Glow
Book By Ken Kessler
is honored to partner with author Ken Kessler in releasing a book timed to the
company's 50th anniversary. Audio Research: Making the Music Glow ($150) describes the people behind the company, designing, manufacturing, fine-tuning, and marketing the audio amplification and source components that have been regarded perpetually as among the best in the industry. Celebrating their first half-century, Audio Research's book tells the story of a manufacturer that helped define high-end audio, with the sole purpose of elevating the sound quality of music in the home.
William Zane "Bill" Johnson established Audio Research in 1970, basing its products on what was then considered by many to be obsolete technology: vacuum tubes. Guided by his passion for music and quality listening with a refusal to fall victim to fashion and design trends of the times, Johnson was revolutionary in sound reproduction. With open access to the
company's archives, the participation of employees, and the support and insights of
Bill's wife, Nancy, Audio Research: Making the Music Glow is filled with rare images, curated reprints of period interviews, the definitive product listing, and a study of what the experts have determined to be the
company's 25 greatest achievements, augmented by fresh photography of each model. Within the pages are the stories of the
company's roots, its development, its evolution, and its tenacious hold on delivering industry standard in music
playback. You can buy

Magnepan MG 3.6 Magneplanar Loudspeaker
Review Getting thin for the summer. Review
By Steven R. Rochlin Loudspeakers come in all
shapes and sizes. From small stand mounted minimonitor to the huge room
hogging 500 lbs. monolithic "Dream Reference Statement".
Virtually every high-quality speaker has many areas it excels in and
areas it leaves a bit to be desired. For it is only you who knows which
part(s) of the music you can live with and without. Nothing is perfect my
friend. Bassheads need not venture into Minimonitor Land while small jazz
ensemble lovers probably can do without the 32 drivers per channel "Dream
Reference Statement." Then there are people such as myself who want
it all. From small duets during the quiet moment in life to big rave
club action for those Saturday night techno parties.
Can one pair of speakers suit all my needs... or yours? In the end is it
true what they say, "size matters?" It is well known the optimum driver would be of extremely
little weight, extremely rigid and have the ability to respond to
electrical signals at blindingly fast rates without over or undershoot. ---> Magnepan MG 3.6

IFA 2021 In Berlin Has Been
Due to the global health uncertainties, this has forced the cancellation of IFA Berlin 2021. Their next trade show for consumer and home electronics will return from September 2nd through 6th, 2022. "The decision was made following detailed conversations with public health experts and multiple stakeholders," says the IFA. "Ultimately, several key global health metrics did not move as fast in the right direction as had been hoped for - from the rapid emergence of new COVID-19 variants, for example in South Asia, to continued uncertainties about the speed of the rollout of vaccination programmes around the world. This in turn is adding uncertainty for the companies that were committed or interested in coming to Berlin, as well as media and visitors – all of whom have to plan well ahead with regards to budgets, investments and travel – not just for IFA, but all similar events around the world."
"Another consideration is the fact that Messe Berlin continues to support the fight against COVID-19 by converting parts of its exhibition area into a vaccination centre and an emergency hospital facility; both are now likely to be required for longer than originally anticipated..... The organisers of IFA are now working with their partners from industry, trade and media to get everything ready for IFA 2022, which will be held as a full-scale live event at the Berlin exhibition grounds."

Auction! Jimi Hendrix Platinum And Gold Discs
Coming up for auction tomorrow, May 27 (2021) are Jimi Hendrix platinum and gold discs belonging to Experience drummer Mitch Mitchell expected to sell for thousands. One platinum and two gold discs originally belonging to the drummer of the Jimi Hendrix Experience are expected to take thousands of British Pounds in Ewbank's Auctions. Mitch Mitchell, who completed the classic Jimi Hendrix Experience line-up alongside Hendrix himself and Noel Redding, played on the bands hits
including "Hey Joe", "Purple Haze", "The Wind Cries Mary", "Voodoo Chile", and "All Along the Watchtower".
Disc being offered include when Hendrix died Mitchell continued to work on the material they had been putting together from earlier in the year for the next studio album. This led to the posthumous release of
The Cry of Love in March 1971. It eventually went platinum, but before it did so, it went gold, commemorating the sale of 500,000 copies of the album and cassette. The second gold disc is for
Crash Landing, another posthumous Hendrix album, released in 1975, which Dee Mitchell has also confirmed came from her
husband's estate. Perhaps most exciting is Mitchell's platinum disc for Bold
As Love, the second studio album of the Jimi Hendrix Experience, released in December 1967, which made the top ten in both the USA (number three) and UK (number five) charts.

Dan D'Agostino MAS Progression M550 And S350 Amplifiers
Dan D'Agostino Master Audio Systems has announced the second generation of Progression Series Amplifiers. First shipped in 2016, the new Progression models take advantage of technology advancements and circuit concepts utilized in the flagship Relentless Mono Amplifier. The new Progression M550 mono amplifier and S350 stereo amplifier ($44,950 per pair and $25,950 respectively) feature improved cooling ability to keep the internal circuitry operating efficiently, all the way to full output. Their Progression M550 monoblock features upgrades to the input stage, output stage, and heat sink design to deliver 550 Watts into 8 Ohms, doubling to 1100 Watts into 4 Ohms (doubling to 2200 Watts into 2 Ohms). The Progression S350 stereo amplifier outputs 350 Watts per channel into 8 Ohms and then doubles to 700 and 1400 into 4 and 2 Ohms respectively.
Both amplifiers employ 48 output transistors powered by a nearly 2000 VA power supply transformer and 100,000 microfarads of power supply storage capacitance. A new power device provides the foundation for an upgraded output stage. This new transistor, first used in the company's Relentless mono amplifier, is said to extend high frequency response, increases power handling by a factor of four and features tighter tolerance gain matching between complementary
NPN / PNP pairs. A wider safe operating area and superior gain linearity provides greater thermal stability throughout the
amplifiers' power delivery. Coupling the new output device to the high efficiency heat sink design affords an increase in operating bias. The higher bias specification has increased the Class A operating range of the amplifiers to 70 Watts for the Progression M550 and 45 Watts for the Progression S350. The result is said by the company to be improved instrument timbre and tonal reproduction for a great percentage of listening.

Auction! Michael Hobson Classic Records Personal Archive #1
Michael Hobson's Classic Records personal archive #1 will be auctioned off during May/June 2021. Their press release says, "From the time Michael Hobson started Classic Records in 1994 until it was sold to Chad Kassem's Acoustic Sounds in 2010, Hobson methodically collected
"MH Personal ARCHIVE" copies of every Classic Records release in various versions including different vinyl formulas, colored vinyl, 180 gram, 200 gram, Flat profile, Super Vinyl Profile and 45rpm editions. As with all archives, no matter how hard the Collector (Hobson) tries, inevitably a few things slip away or develop legs and escape, so the bottom line is that few collections are ever complete. The MH Personal Archive is only missing a few items and as such is undoubtedly one of the most complete collections of Classic Records output in existence."
More importantly, as those who know Hobson and his obsession with making the
"BEST" records possible will attest, he was equally obsessed with having his MH Personal Archive copies be from, not only the 1S (first) stamper, but from the prime point (sweet spot) in the first stamper pressings which was determined to be between 100 and 150 copies from the start of the pressing run. As such, the MH personal archives pressings represent
"THE BEST of the BEST". Interested parties can obtain a spreadsheet of all items in the collection and details of the upcoming auction by e-mailing

World Premiere Review! Bob Carver Cherry 180 Tube Monoblock Amplifier One of the most significant tube amplifiers of the past 60 years!
Review By Dick Olsher Everyone, I'm sure, has by now heard that the
innovative and dare I say legend in his own time, Bob Carver, is back! Carver
LLC is about tube amplifiers, and soon loudspeakers. It is really the tale of
two Bobs: Bob Carver the designer, and Bob Farinelli the business and marketing
hub. Two tube monoblock amps are currently shipping: the Cherry 180 and Black
Beauty 305. Both share the same chassis, but the 180 is optimized for a KT88
output stage while the 305 is designed specifically for the KT120. Although
promoted as a nominal 180 Watt amp, Carver tells me that the Cherry 180 will
deliver about 270 Watts. Although on the surface they may appear to be
conventional push-pull Class AB power amps, there's much more here than meets
the eye. They should be understood as Formula 1 racing car designs, optimized
for high-power performance. Throughout this review I've taken the liberty of
quoting from Bob Carver responses to my many questions. --->

Within this month's editorial, Alan Sircom says,
"It's strange; really good audio equipment is like London buses; you wait for the longest time, then several come along all at once. So it is with this issue. We had already arranged reviews of some really high-performance audio (such as the Magico) when from out of almost nowhere, Linn approached us with the striking new Klimax DSM streamer. These and others are truly ground-breaking products, born at a time when good audio had become popular for the same reasons designing and making good audio had become difficult!
It's exciting and interesting to see just what's been happening during the
planet's most fallow period in more than a century, and those products are finally coming to fruition. Granted there might be some problems along the way – right now,
it's hard to find enough decent cardboard to package up new products because Amazon bought all it could in 2020 – but what were a few months ago giant icebergs in the way of getting good audio are increasingly melting away."

RMAF Show 2021 Update May 17th,
This just in from RMAF: Well, we feel so much better now! Last week we met with the staff of the Gaylord and learned more about their plans for opening conferences this summer. Perhaps the most important thing we learned is that beginning this month, the standard
6' social distancing requirement will be reduced to 3'. Following a 90-day evaluation period monitored by the Tri-County Health Department, the Gaylord staff expects the distancing requirement will be lifted completely. People will be asked to use good judgment when encountering indoor crowds. Although we are under no illusions that the need for caution is over, we are relieved to feel that something akin to
"normal" is in our future!
And so, while we would never want to minimize
anyone's concerns regarding their safety or that of their staff, we are feeling more and more confident that we can move forward with planning our show with our usual optimism. With that in mind, here are some early answers to the questions
we've been fielding. Read more on our RMAF 2021

"A year and a half later, the devastating global effects of the COVID-19 pandemic are still far from over. Fortunately, the successful take-up in vaccines and new treatments, innovations in products and services, and overall strong social and business resilience, afford us relatively high levels of optimism for a strong global economic resurgence. Most macroeconomic and industry reports tell us that while demand for many products was drastically reduced, changes in consumer behavior have also accelerated, and major trending shifts created strong opportunities. As most countries and large economies start to gear up for what promises to be a very strong post-pandemic economic recovery, it becomes clear that the pandemic accelerated technologies and consumer trends by at least a few years."

First Watt Model SIT-1 Monoblock Power
Amplifier Review The power of the First Watt digs deeply into the fabric of music to communicate soul, drama, and passion. Review By Dick
Olsher Imagine a single-ended Class A power amplifier
comprising a single transistor, that is devoid of any feedback, and which
behaves similarly to a power triode? Does this scenario sound too good to be
true? Well, that's exactly what the First Watt SIT-1 is all about. It deploys a
unique type of device, a variant of the JFET, referred to as a static induction
transistor (SIT). It was invented in the early 1970s by Jun-ichi Nishizawa, a
true genius who is considered the "father of Japanese
microelectronics." The SIT enjoyed a brief audio career in power amplifiers
by Yamaha and Sony, but has continued to evolve since then mainly for UHF and
S-band applications in radar and communication satellite systems. It is a
voltage controlled device whereby the signal modulates the electrostatic
potential barrier produced by the gate – the grid like element of the SIT.
Unlike an ordinary FET whose current-voltage characteristics are pentode like,
those of the SIT are triode like. One important consequence of this is the low
output impedance even in single-ended operation. And because of its inherent
low-voltage and high-current characteristics, no output transformer is required
for matching the output stage to a loudspeaker. ---> First Watt Model SIT-1

RIAA Special 301 Report Protecting Creators
From the RIAA press room: The Recording Industry Association of America (RIAA) issued the following statement today by its Chairman & CEO Mitch Glazier on the release of the annual Special 301 Report today by the United States Trade Representative
"The 2021 Special 301 Report highlights both the contributions of American creators to U.S. job creation, wages and economic growth, as well as the continuing challenges we face around the world. Importantly, it also reflects the Biden
Administration's commitment to strong trade policies that protect copyright, boost our
nation's economic prosperity, and foster our cultural leadership.
RIAA welcomes the report's focus on the role that creators and innovators play in creating high-wage jobs and fueling economic recovery. We also appreciate its focus on music community priorities, including challenges to copyright in South Africa and the implementation of the USMCA free trade agreement. And while we continue to believe the United Arab Emirates should be maintained on the Watch List for its longstanding refusal to comply with copyright requirements, we appreciate the
report's clear call for the UAE to implement a meaningful licensing regime and urge the U.S. government to engage intensively with the UAE to resolve this chronic abuse of copyright.
RIAA applauds the rigor and extensive deliberations that went into this report and thanks Ambassador Tai, the USTR and interagency teams that worked tirelessly on
Recording Industry Action Against
Vimeo For Music Content
From the IFPI news room: Recording industry takes action against Vimeo for making available infringing music content.
IFPI, representing the recording industry worldwide, together with its Italian national group FIMI and the Italian anti-piracy organisation FPM, has coordinated a legal action on behalf of its record company members against online content sharing service Vimeo in Italy. The action is based on Vimeo's failure to prevent unlicensed music appearing on its platform.
Commenting on the action, IFPI Chief Executive, Frances Moore, said:
"Vimeo has fallen short of its obligation as an online content sharing service to take effective steps to prevent unlicensed music from being made available on its site. Significant amounts of unlicensed music are being uploaded and reuploaded to its service. That is why the recording industry has taken action against Vimeo in Italy.
Record labels invest heavily in discovering, nurturing, and promoting artists. The making available of unlicensed sound recordings harms their ability to secure a return on their investment which is crucial to their ability to invest in new

Siltech Classic Legend Series Of Cables
Siltech's Classic Legend Series is a revision of the company's multi-award-winning Classic Anniversary Series, which was first launched in 1997. As the company's best-selling product line, the new Classic Legend series
incorporates innovations including the latest development of silver-gold alloy called G9. G9 is said to provide better conductive qualities and improved cable run-in times, meaning far less time is needed for the conductors and insulators to achieve their optimum performance. A new three-layer insulator approach consists of Teflon combined with PEEK (polyether ether ketone). Their research has found that combining specific insulation materials can deliver significant reductions in distortion and improvements in sound.
These multiple layers possess unique properties such as superior thermal stability and physical ruggedness during production and over the life of the cable, as well as better electrical shielding at audio frequencies and more. A third improvement found in Classic Legend is the use of substantially larger conductors. On average, these conductors are approximately double those of the previous generation's cables. Larger conductors contribute to lower resistance throughout the length of the cable and greater current carrying capability when necessary.

Understanding Digital Room Correction Article By Mitch Barnett Of Accurate Sound Modern
Digital Room Correction (DRC) is an often misunderstood subject area. I have
seen many articles written on the subject that don't answer basic questions such
as what problem is DRC trying to solve? How does DRC work? And why, as an
audiophile, should I care? This article endeavors to answer these questions.
Let's start off with what problem DRC is trying to solve.
One can identify the problem fairly quickly by listening to the bass response of
your loudspeakers in your room. Try it along with me. Find some music that has a variety of bass notes. The more the variety, the more frequencies we are testing, just by listening to

World Premiere Review!
Rogue Audio RP-9 Vacuum Tube Stereo Preamplifier Exceeding the listener's expectations. Review By Bob Grossman Rogue
Audio's RP-9 is the latest flagship preamplifier from the ingenious
designs of the American manufacturing workshop of Mark O'Brien. Having an
interest in doing this review of the new RP-9 was a simple decision as a
long-time user of the Rogue RP-7. I have been using the remarkable
powerhouse Rogue Apollo Dark Amps for several years as both a sonic and output
upgrade to my previously owned Rogue 180 Amplifiers that were used to run Magnepan 3.6
speakers. I replaced the Maggie 3.6 speakers with their 20.7
models several years ago and needed more powerful amps. I wondered if the
increased musical experience of moving further up in the Rogue Amplifier line
was going to be repeated with their new preamplifier by going from the RP-7 to
the RP-9 model. However, before proceeding and hearing the RP-9, I
wondered what was going on since the RP-7 has received numerous accolades, recognition, and
rewards. Could designer Mark O'Brien improve upon the noteworthy RP-7 that I
have been enjoying? --->

Allnic Rose Moving Coil Phono
Cartridge Review The essential elements of what makes music sound so good! Review By Tom Lyle I agreed to
review the Allnic Rose low-output moving coil cartridge largely because its
reputation precedes it. This cartridge is designed and made by the same company
that makes the award-winning Blue
Note Best Of 2020 H-7000 vacuum tube phono stereo preamplifier that I
reviewed that year. After listening to this phono cartridge for only a couple of
weeks, I was already quite impressed, even before it was fully broken in.
During the first few weeks of listening to this phono cartridge, for some
reason, I thought that its price was $5999, which I thought was fair, given how
impressed I was so early in the review. One can imagine how surprised I was when
I discovered that this Allnic Rose cartridge sells for $2900. I had to
recalibrate my way of thinking. To make things easier on myself, I attempted not
to think about how much this cartridge cost but simply reviewing the cartridge
and telling you about my experience with it in my system. --->

STEREO Exclusive First Worldwide Review!
Cambridge Evo 150 Integrated Streaming Amplifier Review Remarkable. Truly remarkable. Review By Tom Frantzen Road To
Perfection – Cambridge Audio recently dropped quite a bombshell. Not in the
literal sense, of course, but the newly presented Evo 150 simply has it all and
could (r)evolutionize many a living room. STEREO reports to you with the
exclusive, worldwide first review! The Cambridge Evo 150 is the larger of two models, both of
which Cambridge Audio itself labels as "All-in-One". It comes at a
price of around 2500 Euros, the very similar Evo 75 – lacking the XLR input
and having about half of the output power, which should still be sufficient in
most cases – will cost 500 Euros less. The likewise slightly different DACs in
both devices are each hailing from the top supplier ESS Sabre. Going with our own naming conventions, what we have here
should of course be thought of as an integrated amplifier with a built-in
network player, an "integrated streaming amplifier" in short. It is
worthy to note that the British company will also supply an optional, suitable
CD drive with a proprietary interface in the course of this year. --->
