Within his editorial Noel Keywood says, "If you want a powerful amplifier in a small case, a Class D amplifier from Hypex (Netherlands) has become a popular choice. The company was started by ex-Philips employees in 1996 they say, and I experimented with early modules that even back then delivered clean low-distortion treble something Class Ds were not known for at the time. Their modules have since become a go-to for manufacturers, so no surprise to see them used by Cambridge Audio in their remarkable Evolution 150 all-in-one player that you can read about on p17. Yes it does produce that much power, for all those seduced by a 150 Watt power spec. It also has a remarkable range of ability: I hope you enjoy reading about all its many talents."

Spotify Reports Their Second Quarter 2021 Earnings
Spotify just announced their second quarter 2021 financial performance and it's great news for the music business and musicians worldwide. Revenue of 2.33 billion grew 23% Y/Y in Q2 (or 28% Y/Y on a constant currency basis) and was toward the top end of the company's guidance range due to significant advertising strength and subscriber outperformance. Central bank driven currency devaluation (FX headwinds) of 430 bps were 230 bps greater than expected, primarily driven by the Federal Reserve's
Dollar product weakness versus the ECB's Euro product. Spotify's Premium Revenue grew 17% Y/Y to 2.056 billion (or 20% Y/Y constant currency) while Ad-Supported Revenue was particularly strong, growing 110% Y/Y to 275 million (or 126% Y/Y constant currency).
"Most of our major metrics -- Subscriber growth, Revenue, Gross Margin, and Operating Income -- performed better than expected this quarter," says Spotify. "Our Premium Subscribers grew 20% Y/Y to 165 million in the quarter, towards the upper end of our guidance range and modestly ahead of forecast. We added 7 million subscribers in Q2, which drove healthy double digit Y/Y growth across all regions. We saw strong performance of our Standard product across both Europe and North
America.... Our average monthly Premium churn rate for the quarter was down 23 bps Y/Y and down modestly Q/Q. The Y/Y improvement continues to be driven by the adoption of our higher retention offerings like Duo and Family Plans in addition to growth in high retention regions."

Long Awaited Multi-Channel Pink Floyd The Dark Side Of The
The much anticipated Pink Floyd The Dark Side Of The Moon in hybrid multi-channel SACD is finally
available! This multi-track masterpiece is mixed for 5.1 surround sound and stereo from the original analog master tapes by Pink Floyd Producer / Engineer James Guthrie. According to Acoustic Sounds, "Another classic Pink Floyd title receives the multichannel reissue treatment and Acoustic Sounds and Analogue Productions is once again proud to handle exclusive distribution of this monumental SACD. How lucky we all are to hear this legendary studio recording realize its full potential. The SACD also of course includes a stunning stereo mix. And as this is a hybrid disc, the album is of course also playable on a standard CD player."
"This is Pink Floyd at its collective finest, with everyone contributing. David Gilmour took a huge chunk of the music writing, laying down the chord progressions on "Breathe," "Time," and "Any Colour You Like," plus the singing on the album's best songs.... Known for its complex instrumental textures, the album firmly established Pink Floyd as one of the most innovative bands in rock history. A concept album, its themes explore conflict, greed, time, and mental illness, the latter partly inspired by the deteriorating health of founding member Syd Barrett, who left in 1968."

2021 Is A Milestone Year For Music Streaming
According to TradingPlatforms, during 2021 in the USA there are 100,000,000 users and a 30% penetration rate for online subscription music streaming. "Subscription-based music streaming services have made music more accessible than ever before, with hundreds of millions of subscribers worldwide," says their report. "According to data presented by Tradingplatforms.com, the number of music streaming services users in the US will reach 100M in 2021 and will generate the most revenue globally $8,700,000,000 ($8.7B)...

TradingPlatforms also said that global music streaming revenue to cross the $20B mark in 2021; to reach 900,000,000 users in 2025.
"One of the many benefits gained from music streaming services was its ability to make an extremely wide range of music accessible to the average listener," says Rex Pascual, Editor at Tradingplatforms.com. "However, with music streaming already more than a decade old and competition heating up, services like Spotify are now starting to offer exclusive perks such as pre-releases and concerts to its subscribers in order to stand out. With music streaming in the US hitting 100M users in 2021, the focus for the industry seems to be shifting from accessibility to varying forms of

WBT Earns German Innovation Award 2021
WBT Industrie has been chosen as the winner of the German Innovation Award 2021 in the
medium-sized companies category for its development of "3D gold-plating of connectors using PVD plasma" process (Physical Vapour deposition). This innovation is internally named WBT-PlasmaProtect. With this plant technology it has, for the first time, been possible to develop a significantly more environmentally-friendly process to use instead of the electroplating process used previously. The effectiveness was increased from 20% to 80% by a new 3D process. Energy requirements were reduced by ~26% and resource consumption was reduced by ~35%. At the same time, the long-term stability and contact quality was improved by a thin but extremely pure (high vacuum) and still elastic layer of gold (Hertzian stress). The German Innovation Award is one of the most prestigious awards for new developments
"made in Germany", and is jointly presented by Accenture, EnBW and the magazine
Wirtschafts Woche. Awards are given to companies that change technology and markets with their innovative strength.

Within his editorial, J. Martins' Making Acoustics Personal And Safe says
"This is our annual edition where we pay extra attention to acoustics something that I like to think we actually do every month. After getting the magazine to the printer, I always wish we could publish more contributed articles and we are always receptive to publishing more work in this domain. In particular from those working in the fascinating domain of acoustic measurements, simulation, and even auralization of acoustics. This is an area of significant progress. Software tools and increasingly powerful computation platforms are enabling something that we have all been dreaming about for years: To be able to perform real-time ray-tracing, wave and particles propagation for simulation of acoustic properties, conditions, and interactions. While many still use it mainly for research, this is now part of the basic toolset for education, while acousticians are using it more for both designing new acoustic treatment solutions and full project design. And given the enormous progress that is taking place in structural mechanics, dynamics, and multiphysics simulation, the always-elusive research in areas such as vibration and sound control is now also not only possible but highly recommended."

Kiseki Purple Heart NS Moving Coil Phono
Cartridge Review The sound of sonic art.
Tom Lyle Phono cartridges occupy a reverent place in an
arsenal. The Kiseki Purple Heart NS (new style) moving coil phono cartridge
reviewed here is a good example. Their significance, however, is often under-appreciated by neophytes who
don't understand that cartridges have a shorter lifespan than other
components. The manufacturers are not to blame; after a few years, even the most
robust stylus wears out or the cantilever breaks. The uninitiated or the
financially strapped will frequently opt to replace those elements
(re-tipping), but the DNA of a true audiophile relentlessly demands upgrading to
a better phono cartridge. Luckily, a large majority of manufacturers are willing
to credit the purchase price of an older cartridge towards a new one higher up
in their line. That brings us to the subject of this review, the Kiseki
Purple Heart NS moving coil phono cartridge. In November 2014 I reviewed the excellent Kiseki Blue
priced about a thousand dollars less than the Purple Heart. Those who read the
review know that Kiseki cartridges are manufactured by Herman van den Dungen.... --->

SonicKey Audio Tracking / Watermarking
SonicKey seeks to enables all audio within the world to be identifiable, referenceable, and yes trackable. Claiming to be inaudible, their watermarking technology is
said to easily integrated in to both software and hardware. They also claim to be the first completely inaudible music identification technology.
"SonicData's patented technology is an algorithm that adapts to any sound, identifying and understanding its frequency and harmony," says the
company. "This means that the SonicKey becomes part of the underlying sound of any music or content in which it is encoded. SonicKey is inaudible watermarking. It is fast and performant and through
SonicData's cloud based solutions can encode millions of songs in just a few hours. Any music and sound is now uniquely identifiable with 100 percent accuracy to any version, stream, edit, cut, language, performance or distributed copy."
SonicData may enable rights holders to track their revenues for all content use. SonicKey is said to have a 100% effective detection rate across broadcast and streaming, social media, video sharing, and in-venue use. "While technology has revolutionised the distribution and consumption of music and other content, rights holders have been unable to accurately understand or control its use. The SonicData platform delivers accurate performance and playback identification by encoding a unique SonicKey in to a song, sound track, musical piece or any content with sound."

Raidho TD4.2 Floorstanding
Loudspeaker Review Raidho's TD4.2 delivers the meaning of music.
Tom Lyle I admit it. The pair of TD4.2 speakers that have taken residence in my listening room are
the best speakers I have ever had the pleasure of auditioning. They are also the
most massive, most substantial, and at $122,000 to $142,000 a pair,
the most expensive. It was a bit of a humbling experience unpacking these
speakers. This is because getting them out of their crates and into the
listening room required hired help there was no way I could move these
speakers into the listening room upstairs by myself. Usually, when assigned the
task of moving large speakers, I would enlist a friend or two to help me out,
but in this case, if I attempted to move them as I did with other large
speakers, there would be no way I could get them into my listening room without
damaging the mirror-like, gorgeous walnut finish of this review pair. And so, I
had to hire professionals to the job. --->

Six Reasons Why Subwoofers Are Important For Music Article By
Nick Brown Of SVS There
is a lingering sentiment in the hi-fi community that subwoofers are only for
home theater and the benefits to music playback are suspect or even negative. It's
true that lesser subwoofers are not designed to optimally handle the speed,
detail and nuance of certain music, but it's certainly not a steadfast rule. A great subwoofer elevates the listening experience in a way
no other audio component can, into the tactile realm. Below is a list of six
reasons why a properly engineered and tuned subwoofer is important to music
majority of speakers start dropping off at about 50Hz, which deprives you of the
full depth and clarity of bass tones.A great subwoofer will reach down to 20Hz
or lower, right down to the limit of human hearing. This means you never miss a
note and can even feel the lowest notes from something like a pipe organ, kick
drum, bass guitar or the occasional cannon volley from the 1812 Overture, for a
much more immersive experience. --->

"Have you noticed the important evolution that is taking place in professional audio applications, particularly with commercial installations? The last year and a half caused a business stagnation for many manufacturers of professional audio equipment, but those companies have continued to expand on many of the concepts, features, and technologies that were already under development in 2019, and further accelerated the research to improve their abilities to control, manage, supervise, and monitor vital systems remotely. As in many other technology areas, the pandemic circumstances led to the accelerated adoption of web- and cloud-based tools that were merely being
'considered' and suddenly became obviously essential."

So big they arrived in a Pantechnicon, or
that's what happened when Wharfedale sent me a pair of 2075s from Bradford. Tannoy deliveries, especially of the Westminsters we reviewed in the November 2015 issue, were similarly frightening. And from speakers so large
that's the sound you got too: frightening. I was reminded about all this when reviewing the DeVore Orangutans in this issue, that you can find on p10. This is a
speaker with a generously large sound smoothly delivered. Those that like a big cabinet with looming presence will surely find the DeVore attractive and its sound satisfying."

Hi-Fi? What's That? Roger Skoff writes about our hobby and the non-audiophile world. Article
By Roger Skoff A woman came to my house yesterday to give me a bid on some planned remodeling. When she came in, she sat on the couch in the living room, in what would be a good spot for listening to that
room's sound system and, noticing the large speakers, she commented "Gee, you must like to listen really
LOUD." When I responded that "No, I like to listen really good", she gave me a look of frank bafflement and obviously had no idea at all what I
meant. Although what that woman said took me aback, it probably
shouldn't have. It was hardly the first time I'd ever run across people with not even the slightest understanding of our hobby. One incident that particularly comes to mind is the time, a few years back, when I went to Canada for the Toronto Hi-Fi Show. At the airport, as I was passing through customs, the young lady Customs Agent asked me why I had come to
Canada. ---> Hi-Fi? What's That?

journal will be meaningless to you. Straight and simple, it is quintessential
Mid-Century Modern design. In terms of where American mainstream home
furnishings is today, it is spot on. In terms of the interior design of people
that can afford this speaker, well, you may need to adjust. The original Eames
lounge chair and ottoman is still available from Herman Miller for $7000 and the
knock-off can be had for less than $1300. Many contemporary Scandinavian
recliners will also work very nicely. Ekornes is not your only option. If you've
got a dedicated listening room (and most people considering a $37,000 speaker
will) this should not be a problem. As a two-way dipole, it needs to be 30"
to 40" out from the front wall behind it. It will have a definite presence
in your room. --->

The FinkTeam Kim Speakers An expansive soundscape you can almost step into to join the fun! Review By Ron Nagle So
it was just another day trolling the internet trying to find something audio
that was new and was just a bit out of the ordinary. That thing needed to be
something cut from a very different cloth. That's when I found the FinkTeam
Kim stand-mounted loudspeakers. Three days later strictly by a serendipitous sequence of events,
my New York Audio Society joined a Zoom meeting with the man behind all of that
Fink-ology. The FinkTeam was formed from the fertile mind of a renowned German
speaker designer named Karl Heinz Fink. There were a lot of questions asked,
some of them not directly concerning the Fink design team. More specifically I
wanted to ask in detail what new thinking went into the Kim speaker design. But
it did not happen, I was only one of many participants at that meeting. But I
came away from that meeting understanding that after years working as a speaker
design expert for other people, KHF decided to design a new speaker adhering to
the things that he values most. --->

Verdant Audio Blackthorn 1 Monitor
Speakers An over-achieving monitor with a musical performance well beyond its' modest size. Review By Dr. Michael Bump I first had the pleasure of meeting Scott
Bierfeldt, President and Chief Designer
at Verdant Audio, at AXPONA 2019 in a
by-chance meeting. I was planning on heading out earlier than expected on
Sunday, as the snow was starting to come down (attendees may recall), and I was
a bit nervous about the six-hour mark. drive home to the cornfields of Missouri.
Nevertheless, the rooms beckoned me back for one more quick tour that morning,
where I happened to walk by a familiar blue glow within the Verdant Audio room.
At the center of a very attractive system were a
pair of stunning Art Audio Quartet 845 push-pull monoblocks. I was familiar with
Art Audio from an introduction years prior to their 50-Watt SET Adagios, and was
aware that Verdant Audio had re-introduced the UK company to the U.S. earlier
that year as the sole domestic distributor. Needless to say, my curiosity was
piqued stepping into the room noting several examples of Art Audio pieces, as
well as the premiere of two monitor designs created by Scott, under the Verdant
Audio name. --->

JERN 11S Compact Loudspeaker Review A well-balanced speaker that presents a lovely neutral rendition of music. Review By Robert Jorgensen What is a
poor reviewer to do when he would rather put on some more music than write on
the review? My wife might say "Suck it up and get on with it". This could imply
that I do not want to say anything but that's not the case. I am just enjoying
the music too much. There is a bit of a backstory here. If I remember well, the first time I saw the JERN Speakers was
a couple of years ago at the ISE Exhibition in Amsterdam. Ole Lund Christensen,
whom I have known for 20 odd years, was banging away on a piece of steel, a
piece of aluminum, and his very heavy cabinets made of a special kind of cast
iron using a little hammer. There is a video floating around on YouTube where he
does it with a piece of aluminum and a piece of his special "Vibrakill" cast
iron. It was very instructive since both the steel and the aluminum
rang like bells and the JERN cabinet just gave a dull thud. As he explained that
was exactly the point of the demo. ---> JERN 11S

New Horizon 301 Vinyl LP Turntable Review A vinyl revival! Review By Paul Schumann This past
year of my audio reviewing has had quite a vinyl flavor. Last summer, I reviewed
phono amplifier. This past fall, I listened to the Aric
Audio Unlimited II Preamp with an included phono stage. The turntable I
used with both is the oldest piece of gear I own, a Yamaha P-350 turntable.
Looking at that old piece of gear takes me back to a very different time in
audio and always makes me realize how much time has passed since I purchased it.
Before I bought the Yamaha P-350, my system consisted of my
dad's old Dynaco preamp and amp, a Pioneer tape deck, and a pair of ADS L620
speakers. At that time I was listening to prerecorded tapes or ones I recorded
on friends' systems. Forgive me, I was only 18. I bought the ADS speakers at an
audio salon called Audio Concepts adjacent to the University of Texas campus in
Austin. That place was my gateway to what became high-end audio. It was there I
was introduced to Klipsch, Magnepan, Theil, and Advent speakers. Their main
electronics were Nakamichi and Yamaha. --->

NPS 1260 3D Enhancer Solution Review A big leap toward reality! Review By Rick Becker A recent discussion
in the Audiogon Forum asked "How much reality do you really need? Some of the
If it's on the recording, I want to hear it.
For my critical listening, I want the full Monty.
It's the nature of man to want more or different.
Reality is highly overrated.
Just FYI, "reality" is not really my jam.
Enough to hold my attention.
I like it, I love it, I want some more of it.
If a recording needs a playback system in order for you to
hear it, and every system is different, how do you really ever know what's
on the recording?
...My only ultimate goal is to enjoy music. Reality blah blah-blah. --->
