High-Precision Electrostatic Laminate Transducer
The Sonoma was the world’s first headphone system to use
the High-Precision Electrostatic Laminate (HPEL) audio
transducer developed by Warwick Acoustics
Ltd. To date it has won 25 industry
awards and received testimonials from
audiophiles and recording professionals
from around the world.With the BRAVURA we have invested
3 years of HPEL development to
refine our core patented technology
to further improve upon all the
benefits for which electrostatics are
famous. The latest evolution of the
single-ended HPEL uses a new stator
design and more advanced materials
resulting in ultra low distortion,
increased SPL and a wider bandwidth.
Each HPEL is handmade and individually
matched resulting in a listening experience with unrivalled
transparency and musicality.
Injected Magnesium Ear-Cups
With excellent strength-to-weight ratio, high stiffness, superior
acoustical damping and outstanding RFI/EMI shielding,
magnesium is the ideal material in which to house the
HPEL to ensure optimal performance. It’s low weight also
contributes to outstanding headphone comfort and reduced
user fatigue.
Handmade Hair Sheep Ear Pads
Ensuring comfort during long listening sessions, the BRAVURA
ear-pads are handmade from top-grain, Cabretta hair sheep
leather, known for its light weight, durability and softness.
Luxury Headband
The BRAVURA uses a version of the headband designed for
our flagship APERIO headphone. Its hand stitched finish
delivers the ultimate in comfort and luxury.
Custom Low-Capacitance Cable
We developed a bespoke ultra-low capacitance cable to
guarantee optimal signal transfer between amplifier and
headphone. Manufactured in collaboration with ATLAS and
LEMO, the cable is strengthened with Kevlar between the
inner cores, and uses high-precision self-latching LEMO
connectors. A high quality woven Moplen outer braiding
with soft feel and ultra-wear resistance ensures a luxury
user experience.
Class-A Energizing Amplifier
Like all electrostatics, the HPEL
requires a high-voltage drive
amplifier in order to function.
The supplied drive comes from
an optimally matched, highperformance,
discrete FET Class-A
amplifier with very low distortion and wide bandwidth. The
amplifier is encased in a completely shielded, machined
aluminum enclosure to ensure isolation from all interference
sources, and provides USB and coax S/PDIF digital as well as
RCA analog inputs. The USB input accepts all Hi-Res Audio
formats up to 32-bit/384 kHz PCM and DSD via DoP (DSD64
and DSD128), while the S/PDIF input accepts all PCM formats
up to 24-bit/192 kHz.
ESS SABRE Reference DAC
ESS is universally recognized as the world’s premium DAC chip
manufacturer, and we have opted for their 32-bit Reference
DAC. Each stereo DAC chip is operated in mono mode to
provide a measured 129 dB signal-to-noise ratio.
Custom 64-Bit Double-Precision Fixed-Point DSP
In order to obtain the desired response at the output of the
headphones, we digitally process all signals using custom
64-bit double-precision fixed-point arithmetic. Fixed-point is
known to be superior in the world of audio processing, and our
64-bit arithmetic exceeds even the performance of professional
audio workstations.
AKM Premium ADC
All incoming analog signals must be converted to digital
ahead of the DSP, and for this we use a multi-channel
32-bit/384 kHz AKM Premium ADC to deliver a measured
signal-to-noise ratio in excess of 120 dB.
Superior USB Data Cable
With gold-plated connectors and a silver-plated data path, the
supplied USB cable, co-developed with Straight Wire, is the
perfect connection between your digital music source and the
Sonoma M1 system.
Custom Universal Voltage PSU
Our custom-designed, universal voltage switch-mode
power supply utilizes a fixed frequency design optimized
for low noise within the audio bandwidth. To ensure a good
connection with the amplifier unit, we use high-performance,
locking DC power connectors. All audio circuitry within the
amplifier is supplied by a secondary stage of ultra-low noise,
high current linear regulation
