Reference 1.1 12AU7 x 2 Tube Line stage
£2495
R1.1 represents the top model of Opera Audio's current
range of per-amplifiers. It is a 20dB gain line stage
pre-amplifier using improved SRPP circuit with no global
negative feedback. The equipment top uses cherry wood while
equipment feet are brass cones for improved shock
absorption. Front plate is of machined aluminum.
The
internal components used are among the finest available in
the world today. The potentiometer uses the single stereo
ELMA 24 position series attenuator with 46 Holco 1%
precision resistors. Apart from having excellent sonic
characteristic, it guarantees the sound stage precision at
any volume level. The capacitors used for signal coupling
is both the exotic US MultiCap RTX and the Rel-Cap.
Resistors used is a combination of Holco and Chinese made
precision aerospace low temperature drift version. All
connections are point to point wiring using Kimber high
purity copper hook up wire. The circuit board acts as a
support frame for the tubes and other components and actual
point to point wirings are done beneath the circuit board.
The
two tubes used in the main circuit is the fabulous sounding
12AU7 NOS made in the 50/60s. Due to limited supply they
are very hard to find in the market and price-wise
expensive but absolutely one of the very best. In order
that users can try out different types of 12AU7, the R1.1
is designed to use components that has very little colored
sound of their own. In this way, during tube rolling the
R1.1 can clearly show off the sound of the tube itself. A
lot of satisfaction will then be achieved by trying out
other exotic tubes like the Telefunken and Mullard.
Good
quality pre-amplifier calls for a good quality power
supply. The power transformer and choke is shielded from
the circuit board. A special silicon steel EI type power
transformer and choke with good high frequency response is
used together with large Solen MKP metallized polypropylene
filtering capacitor. Its filtering characteristic is very
uniform across the frequency range and adds to the purity
of the sound.
To reduce the microphone effect, two Pearl tube coolers are
used. Not only they are effective in reducing microphone
effect, they are also a very good heat sink which can
greatly extend tube life. Other convenient features are
added like the -10dB muting switch, which can reduce the
usage of the expensive potentiometer and as a result
extends its life.
Reference 150L Remote Control Integrated Hybrid Amplifier
(6H30S/S 120W)
£1195
Reference
150 Linear, as the upgraded version of original Reference
150, is an completely new design based on the COOL Class A
technology developed from Calaf, and combined with the well
concerned 6H30 tube buffer preamp stage with technology
inherited from the original Reference 150 hybrid amplifier.
Same outlook same function and a lot better sound
performance.
Combined
the advantage of class AB and the class A technology, the
Cool Class A technology actually achieved same linear sound
performance essentially but without normal need of big
electrical current, as Class A does.
- 120 watt output power, screen display equipped
- Relay switched input source selector
- Digitally controlled 6H30 tube preamp stage
- Cool Class A technology applied in amplifier stage
Reference 9.9 Mono block Tube Power Amplifier (845 SE,
28W)
pair £4795
The
Reference 9.9 monoblock tube power amplifier is the
matching top of the range amplifier for the R1.1. Similar
to R1.1, the top uses cherry wood with large machined
aluminum front plate. Each channel uses a direct heated
triode Shuguang 845 for single-ended class A amplification.
First stage goes through a Siemens 60s NOS E88CC and US
5687 NOS as the powerful driver stage to realize an output
power of 28W, with no global negative feedback. Point to
point wirings are used with Kimber high purity copper hook
up wire. Resistors are Chinese military grade metal film.
Signal coupling capacitors are from Rel-Cap/PPMF. R9.9 has
very good driving power due to a strong power supply and
well designed output transformer.
PM-2
Phono Stage for MM/MC Cartridges
(12AX7x2) £850
Besides MM, PM-2 is also enable to be received the fragile
MC cartridge output directly. We hope you agree with us and
most of satisfied users that these sets really act as
lengths of pure copper cable in the LP system.
Cyber-800 Mono block Tube Power Amplifier (6CA7 P/P
parallel,78W]
pair £2995
The
Cyber 800 are a 'no compromise' Reference version of the
already excellent M800SE Monoblocks. The circuitry is
basically the same although the input stage of the Cyber
Series is used and the output stages uses 6CA7 tubes
instead of the EL34 in the M800. Although these two tubes
are basically the same, the 6CA7 gives a better controlled
and deeper bass performance when used in this
configuration. The more advanced and heavier duty Cyber
power supplies are also used. These improvements added to
the absolutely awesome build quality of the Cyber cases
result in an especially impressive amplifier, both
sonically and visually.
Cyber-211 Mono block Tube Power Amplifier (211 SE,
16W)
pair £4295
The Cyber-211 is a single-ended class A mono power
amplifier. It uses no global feedback. The 5687 is a high
mu dual triode, and acts as one tube with drive stage. AC
voltage applied to the input goes first to the E88CC and
then to the grid of the 5687. The 5687 provides voltage
gain and drives the 211/845 output tube. The 211/845 is
transformer-coupled to the load. (In this case, the
speaker).

10W)pair
£4995
Cyber 300BD Mono block Tube Power Amplifier (300B P/P
18W]
pair £5495
The
Cyber-300 delivers 15 Watts RMS at 1kHz with a total
harmonic distortion of less than 1% (5 Watt, 1kHz). It
offers a frequency response of 2Hz - 50kHz (-3dB points at
10 Watts). It has an input sensitivity of 0.8 volts, an
input impedence of 100K ohms and a user-selectable output
of either 4 or 8 ohms, with a signal to noise ratio of
90dB, using 100 Watts.

Cyber Signature 10 Remote Control Integrated 2A3 11w P/P
amplfier
£1395
With
suitable speakers, the Cyber-10 Signature is a gutsy
integrated amplifier with huge dynamics. It sounds
muscular, detailed, and smooth. The Cyber-10 Signature
handled vocals with noteworthy clarity and intelligibility.
It came close to matching the sound of much more expensive
reference electronics, at just over one-third their cost.
If you need even more power, Opera Audio offers the
Cyber-100S Signature integrated amp, which uses 300B
triodes to produce 22Wpc. For fans of low-power tubes,
Opera Audio's various product lines may prove interesting
and enticing.
Cyber Signature 100S Remote Control Integrated 300B 22w P/P
Amplifier
£1595
The Consonance Cyber 100s signature sounds good. Pace,
rhythm and Timing are intact; it doesn't boogie like a
Naim, but it's not turgid like some high-end pretenders.
Musical qualities are present, as one would hope.
Instruments seem to have their natural timbre with no undue
emphasis on any particular aspect of performance or
frequency band. Some amplifiers seem to favour certain
parts of the spectrum, like obvious bass or beguiling
midrange, but this amplifier seems even handed in its
presentation. In basic £1595 form the Consonance Cyber 100
signature represents excellent value for money, continuing
the present trend for bargain Chinese audio. This amplifier
hints at many high-end qualities, that become more apparent
as the upgrade path of Ella Baby mains lead and TJ
Meshplate valves is followed by the proud owner.
