PHX High-End Acoustic Drums
The PHX Series, from the YAMAHA Drum Laboratory
We redefined what a high-end drum-set was
when we introduced Recording Custom in the 1970s. With the introduction
of PHX, we set the bar even higher by creating the ultimate musical
instrument for drummers.
PHX TQF:Turquoise Fade / Gloss Finish / Ash
The shells of the PHX are 11-ply hybrid shells. The woods used are
progressively harder from the center ply to the outer plies. The center
ply is jatoba; this is a very hard wood' and it "anchors" the
fundamental of the shell. Sandwiched on either side of this is kapur.
This wood is in the mahogany family and adds warmth to the sound of the
drum. The inner and outer plies are maple, except in the case of drums
using the optional burled ash outer ply. These drums use an outer
half-ply each of maple and burled ash. Maple rounds out the tone adding
high and mid frequencies to the shell.
Polar White
All drums have a 30° bearing edge, but each "family" of drums uses a
different profile. Bass drums have a sharper edge cut toward the outer
plies. This gives the bass drums attack and shortens the decay. Floor
toms have a slightly rounded edge to give them a perfect balance of
attack and sustain, making them very articulate at all dynamic levels.
Toms have an even more rounded profile for warmth and sustain. This
combination of shell composition and bearing edges makes PHX what many
of our artists described as "the most musical drums [they] have ever
played".
Textured Amber Sunburst
PHX uses redesigned versions of the Nouveau lug and YESS. The new lug
mounts on a square hook rather than a round post. This keeps the tension
rod in perfect vertical alignment and eliminates the need to use two
hands while tuning the drum. We used the aluminum die-cast hoops made
popular on our Absolute series for PHX. These hoops are very light but
rigid, giving you the open, warm sound of a triple-flanged hoop and the
accurate tuning of a die-cast hoop. Lugs and hoops are available in
chrome or gold. The new version of the YESS mounting system supports the drum at the top and bottom. The new version mounts the tom bracket onto a piece of the shell, and that wooden plate is isolated or shock-mounted using rubber grommets. A 3-piece fastening system is used to attach the new YESS to the shell, and the inside and outside fasteners do not touch. This system totally isolates the drum and allows the full tone to come through and maximizes sustain.

Soavo NS-F901Loudsepaker
Yamaha Soavo NS-F901
The NS-F901 offers beautifully designed speakers with an elegant
piano finish. Capable of achieving transparent sound from data-rich,
high resolution sound sources with excellent response, the NS-F901
speaker delivers musical excitement with outstanding expressiveness.
- New A-PMD midrange reproduces high resolution sources with rich, clear and detailed sound
- New A-PMD woofer provides low range reproduction with abundant power and responsiveness
- Aluminum dome tweeter with DC-Diaphragm and neodymium magnet
- Innovative cabinet design (non-parallel surfaces)
- 3-way mitered joint construction
- 2-chamber cabinet (woofer and midrange separated by slanted partition) with vertical bracing
- Highest quality parts including Solen capacitors in the networks
The design of the cabinet is of course extremely important if the aim is
to create a speaker with superior reproduction capabilities. The goal
was to reduce standing waves to ensure highest accuracy, as well as to
provide a full, three-dimensional sound with an awesome feeling of
depth. The solution was to design a cabinet with non-parallel surfaces,
having the woofer and midrange sections divided by a slanted partition,
and strengthening the entire enclosure with vertical ladder bracing.
Another important point is the 3-way mitered construction of the cabinet
joints, achieved thanks to Yamaha’s excellence in woodworking. This
technique ensures extremely tight joints so the entire cabinet behaves
as a single unit, providing tight, powerful and accurate bass
reproduction.
The NS-F901 adopts Yamaha’s unique new A-PMD (advanced polymer-injected
mica diaphragm) with improved cone paper in order to reproduce high
resolution sound sources. Taking advantage of the strong points of the
A-PMD—extreme lightness, rigidity and stability—the speaker achieves
smoothness, very fast response and sound with good dissemination,
reproducing information-rich sound sources with an impressive feeling of
density. The A-PMD incorporates a powerful magnetic circuit with a
large neodymium magnet and a highly stiff aluminum diecast frame that
increases the aperture ratio, achieving outstanding power handling and
responsiveness in the mid frequency range - the heart of the music. The
rubber surround, a spider made by Kurt Müller of Germany and meticulous
tuning also contribute to the reproduction of high quality music and
movie sound.
The bass unit also adopts the new A-PMD with a paper cone upgraded for
the reproduction of high resolution sound. The use of a large ferrite
non-shielded magnet ensures high drive power that provides prodigious
bass volume. By utilizing high quality parts such as a high rigidity
aluminum diecast frame that dampens resonance, it reproduces bass with a
deep sense of scale, achieving both power and speed, leaking out of the
speaker cone. This means the full power of the waves is forced out
through the air port, resulting in clear, powerful bass.
The 1” dome tweeter is made of aluminum for both hardness and
responsiveness and like the midrange unit, uses a neodymium magnet. It
delivers sound that links the medium and high ranges with natural
smoothness and transparency. Firmly integrating the diaphragm and voice
coil and using a thick surround material increases the sound density and
resolution in the high range. With a heavy aluminum diecast tweeter
plate that minimizes unwanted resonances and an extremely fine mesh
grill that provides ideal sound dissemination, it faithfully reproduces
dense sound atmospheres and nuances from high resolution sound sources.
The crossover networks employ the highest quality parts, including Solen
metalized polypropylene capacitors and large iron-core coils with
carefully selected wire. All parts are connected by directly soldering
each one individually, instead of using printed circuit boards, further
contributing to the rich and vivid sound. Finally, meticulous sound
tuning ensures optimum transitions between drivers for smooth and
natural sound across the entire frequency range.

Yamaha Aventage RX-A3040 AV Receiver Reviewed
Yamaha has enjoyed quite a bit of success with the introduction of
its premium Aventage line of AV receivers and separates. While the
Aventage line has been available for a while, it remains quite
competitive in its performance, features, and connectivity; a recent
firmware update added Dolby Atmos and Dolby Surround modes. I'll point
you to this refresher on all things Dolby Atmos if you need it.

Aventage line has been available for a while, it remains quite
competitive in its performance, features, and connectivity; a recent

you to this refresher on all things Dolby Atmos if you need it.
Sitting at the top of the Aventage receiver
lineup is the RX-A3040, priced at $2,199. It is billed as a 9.2-channel
receiver, as it provides both control and amplification for nine
channels and up to two subwoofers in a variety of configurations.
However, it is capable of providing control for two additional channels,
as long as you have an external amplifier to power them. The receiver
includes two of ESS Technology's high-performance DACs: the 32-bit
ESS9016 processes the seven main channels, while the 24-bit ESS9006
processes the front and rear presence (or overhead) speakers and two subwoofer channels.

Features abound with the RX-A3040. This networkable receiver has
built-in apps for Internet radio and streaming services such as
Rhapsody, Spotify, SiriusXM, Pandora, and others. Built-in WiFi capability allows for a wireless connection to your router, and you can connect to Apple devices via AirPlay or an HTC phone via the HTC
Connect app. The Yamaha can decode most music formats, including WAV and
FLAC (both up to 24-bit/192-kHz), Apple's ALAC, and others. USB and MHL
ports allow for the connection of a wide gamut of devices. Advanced HDMI
zone switching allows you to output any source to a second zone through
HDMI (analog audio is also available in a third zone). The RX-A3040 can
pass through and upscale to 4K/60 Ultra HD;
however, it's not HDCP 2.2-compliant, and Yamaha does not plan to offer
an upgrade path, so you will need a workaround if you plan to embrace
Ultra HD Blu-ray
in the near future. There is even a phono input (MM cartridges) for
connecting a turntable, so there's no need to give up your vinyl.

The Hookup
The RX-A3040 chassis weighs just shy
of a hefty 40 pounds and carries a slew of connectivity features,
including eight HDMI inputs and two outputs--plenty for all your
sources. (Visit Yamaha's website for a full rundown of connection options.) I used the first two HDMI inputs for my AT&T U-Verse box for TV and my Oppo BDP-105 for all spinning-disc sources. With the Yamaha set to handle all video processing and switching, I sent HDMI output to my BenQ W7000 projector, displaying to my Elite Screens Spectrum 128-inch screen. I ran speaker wire
to my usual 5.1 speaker configuration with the pair of Salk Soundscape
12 speakers serving as front left and right channels, a Salk Soundscape
7C as center, and the B&W CM6 S2 in the surround role. I connected
my SVS PC-13 Ultra subwoofer to one of the two subwoofer outs on the Yamaha.

my SVS PC-13 Ultra subwoofer to one of the two subwoofer outs on the Yamaha.
For the Atmos channels, Atlantic Technology was kind enough to
provide two pairs of the 44-DA Atmos-enabled speaker modules (review
coming soon) to complete a 5.1.4 Atmos configuration. Since Atmos
capability was not enabled out of the box, I downloaded the new firmware
to get it. Next, I set up my speakers using Yamaha's proprietary YPAO.
The version of YPAO included with the RX-A3040 uniquely includes 3D
and Angle measurement, which is not an advancement to be taken lightly.
Our Yamaha rep describes these options like this: "The Angle measurement
is used to correct for speaker placement that deviates from the
commonly used ITU-r placement. Furniture, windows and room layout can
prevent many people from placing speakers in the proper location. By
knowing where all speakers are placed in relation to the prime listening
spot, the DSP processing can image the signal to more closely match ITU
suggestions. Meanwhile, the Height Angle
measurement is used, among other things, to give the Atmos decoder more
accurate data on how to map the individual sound objects within the
listening room. If the receiver knows that the front right overhead
speaker is 45 degrees to the front instead of 60 degrees, the decoder
can more accurately place the sound of a mosquito, for instance, in the
three-dimensional confines of the room."

For an Atmos setup, I needed to make a few tweaks before running
YPAO. First, I enabled 3D and Angle and multipoint (this makes for a
longer setup time, but allows YPAO to take measurements at multiple
points and create a smoother sound-field across multiple seating
positions, such as an entire couch). Then I set the front height and
rear presence speakers to the setting for Atmos-enabled speakers.
Running through YPAO took about 20 minutes or so, and YPAO got most
things correct. It correctly detected the presence of all speakers, and
its distances and levels were accurate. My surround and rear presence
speakers were both set to large, however, and crossover points were set a
little too low given the speaker sets. I can't really fault YPAO for
this, as I happened to place my surrounds in the back corners of the
room with the rear Atmos modules on top, and corners are known to
reinforce bass. I made a couple of manual adjustments for this, and I
was on on my way...although I must note that YPAO did not allow me to
set the exact crossover point of 150 Hz that Atlantic Tech recommends
for the Atmos modules, but forced me to choose between 120 Hz and 160
Hz. I chose 160 Hz to be closer to the recommended setting.

Performance
I started off with some two-channel
music: Wynton Marsalis' album Marsalis Standard Time Vol. 1 (SACD,
Columbia). Initial testing showed that my power-hungry Salk L/R speakers
were a little too much for the Yamaha to handle. The RX-A3040 boasts a
power rating of 150 watts per channel with two channels driven, which is
the minimum power amplification recommended for my speakers. So, while
the Yamaha stretched admirably to drive the Salks, it couldn't stretch
quite far enough get the best performance out of them. Swapping out my
Salks for my B&W CM6 S2 bookshelf speakers
made for a rich, beautiful sound. Bass lines were tight and
well-defined, piano notes were rich and had the heft I expected, and
Marsalis' trumpet sang with all its squeaky nuances in place.

| A-S3000 Black |
In order to achieve the absolute purest signal transmission, capable of communicating even the most subtle nuances of the music and its powerful dynamism—for example, reproducing powerful, agile low frequencies and portraying all the emotional nuances of the human voice—we've methodically pursued low impedance throughout the A-S3000. Using a double construction design creates space for cables under the bottom of the chassis, enabling the shortest cable path for the supply of power from the transformer to the power stage and for the audio signal transmission path. This helps to eliminate signal transmission loss and to smoothly supply power, even during high-volume transients, and allows more direct audio reproduction without even the slightest adverse effect on the music. Also, the three-dimensional inner frame to which the power transformer is mounted is copper-plated. Extremely low impedance is assured by lowering the ground potential. This sharply lowers the impact of noise and delivers a profound and richly emotional sound—one that perfectly communicates all the original expression of the artist.
The top panel and the front panel are made of aluminum, a non-magnetic material, in order to eliminate any adverse effect on the audio signals. In the course of strictest examination of the sound quality, the front panel thickness was set at 0.28” and the top panel was set at 0.24” . This helps to realize an exceptionally natural, spacious sound by providing a highly rigid chassis structure and at the same time, skillfully controlling the impact of vibration. Moreover, heat dissipation openings on the top panel were formed by high precision cutting from both sides—front and back—of the panel and finished with thorough scrupulous attention to every detail. Stylish slits in the center, matching the companion CD-S3000 and its design, strongly emphasize the powerful power source unit inside by having the same width as the power transformer.
The amplifier circuit design features independent preamplifier and power amplifier blocks and perfect left-right symmetry. Separation of the preamplifier, which handles low energy signals, from the power amplifier, which handles high-energy amplified signals, greatly reduces sound deterioration caused by mutual interference. Moreover, the left-right symmetrical design, which keeps the left and right power stages completely separate, ensures greater channel separation and enhances clarity of the stereo image.
The basic design of the power amplifier circuit adopts Yamaha’s proprietary Floating and Balanced Power Amplifier technology. Adopting output elements with the same polarity on the plus and minus sides of the output stage and also completely separating the NFB (Negative Feedback) circuit and power supply into a total of four plus and minus sides of the left and right channels, results in thoroughly symmetric push-pull operation of the output stage. Completely floating the entire power amplifier circuit from the ground removes any negative impact of minute voltage fluctuations or ground noise. Moreover, the output elements are comprised of MOSFETs, which provide a warm and natural sonic character. The use of MOSFETs, which have the same polarity on the plus and minus sides, further evolves the ideal of a complete symmetrical design, to eliminate sound quality variations due to difference in polarity—a major distinguishing characteristic of the Floating and Balanced Power Amplifier—resulting in sound with a superior signal-to-noise ratio and a superbly well-defined sound field.
The A-S3000 features fully balanced signal transmission. Moreover, the control system circuits (volume, tone, etc.) of the preamplifier feature totally balanced operation, realizing ideal balance in all stages.
The cabling of the power transformer adopts an ingenious method in order to significantly reduce impedance. The winding of the transformer itself is directly connected to the terminal with a screw, unlike with conventional cabling. This enables a power supply which thoroughly limits connection loss and energy loss caused by soldering. The toroidal transformer was selected with top priority on sound quality, contributing superior strength, as well as a profoundly natural and spacious sound.
In order to completely eliminate signal energy loss, important parts of even the circuits employ screw connections. In addition to wiring of the block capacitor of the power unit—which is the real heart of the amplifier and as such requires high power—screw connections were adopted for all crucial spots of signal transmission, including the connection of the preamplifier circuit with the power amplifier circuit, and the cabling to the speaker terminals from the output stage of the power amplifier. In addition to making the signal path as short as possible, this significantly lowers the impedance and greatly reduces signal loss.
The A-S3000 features large level meters on the front panel, giving a direct visual sense of the dynamics and pulse of the music. These beautiful meters are softly illuminated by LED, lending a warm, lamplight look. The meter indicators can, in addition to the VU display, be switched to peak display, and can be selected according to the user’s preference. Moreover, the glass window of the meters is diagonally cut and precision-fit to the back surface of the front panel, leaving no gaps and using no screws for connection—lending an exceptionally elegant appearance to the unit.

As befits a top-end audio component, the A-S3000 gives off the presence of a fine musical instrument, with absolutely no screws or fasteners that can be seen from the outside. Every single aspect of its construction and design exudes master craftsmanship and reflects an obsession with quality—a truly musical quality possible only for Yamaha, a world class musical instrument manufacturer. The amplifier with its refined design has been meticulously finished by the skillful use of advanced processing technologies: integrating the top panel and side wood connection, leaving no gaps while using different materials—metal and wood—for the connection.
The speaker terminals are the final link in the audio chain of this amplifier and have also been designed with meticulous obsession. The screw-type terminals have large handles and feature an original design that has been crafted by cutting pure brass to enable a secure connection with no reduction in sound quality. Moreover, the shape conforms nicely to the human fingers—not only creating an elegant visual impression, but also allowing users to turn them easily and to firmly tighten them with minimal force.
Since the controls—the volume dial, switches and so on—are the parts of the amplifier which users actually touch and feel directly, their surface texture and design were created with the strictest attention to detail. Individual controls such as the volume or input switching dials, emanate a richly elegant feel thanks to the use of cut aluminum knobs. Switches, including the power switch, were made with obsessive attention to texture in every detail; they were shaped with refined craftsmanship so that when they are raised or lowered, the gap between the switch and panel surface is impossible to see.
The supplied remote control features a design complementary to the aluminum panel of the amplifier itself, with a simple, easy-to-understand button layout and gorgeous metallic texture. In addition to the basic volume adjustment and input switching controls of the A-S3000, it can also be used for operation of the companion CD-S3000
