051 INTEGRATED AMPLIFIER

051 Integrated Amplifier

The Rondo Line integrated amplifier 051 seamlessly joins in with the league of Burmester integrated amps. Resulting from the Burmester X-Amp circuit technology, adopted from the 032, the 051 operates with a wide class-A range and is as a result extremely resistant to distortion.

For the benefit of the sound we deliberately sacrificed a couple of Watts output power on paper. Paired with its ability to drive complex loads, the 051 is capable of accentuating the best performance of almost every speaker.

The 051 offers ultra-stable binding posts for speaker cables that can accommodate even large cable lugs. The same binding posts are used for all Burmester speakers. For the integration into home theatre systems, the 051 has a surround through-put. In addition to that, it is completely DC-coupled and equipped with fully balanced amplification stages.

Just like the larger 032 and 082 integrated amplifiers of the Classic Line, the 051 is standard-equipped with a tone control section. Another part of the 051’s convenient features is the 85-step balance control. The tone controls can be bypassed completely, and are therefore detachable without the slightest sacrifice regarding the sound.

CREEK

DESTINY

MSRP US $2,494.00

The Destiny integrated amplifier will continue to produce world beating audio performance, through its continued use of discrete analogue MOS-FET circuitry which was first developed for Creek’s amplification products in 1993. This circuitry has continued to be used with great success since that time.
A major improvement in the Destiny over earlier Creek amplifiers has been in the area of separating power supply and voltage referencing circuitry for each channel. Dedicated windings on the new and up-rated mains transformer achieves Greater Than 100 Watts into 8 Ohm operation.
In addition Creek has upgraded the circuitry that controls the protection of the amplifier and ancillary products under fault conditions. Protection of the amplifier and ancillary products under fault conditions is facilitated by an array of sensors and measurement circuits feeding-back information to the micro controller that monitors the amplifier constantly for over-temperature, over-current, DC offsets, power supply status and over-drive situations. If any of these conditions is exceeded the microcontroller will take the appropriate corrective action. This can include, muting the input signal, separating the speaker outputs and, in extreme cases, switching off the mains supply to the power amplifier circuitry.It continues, as before, to control the volume by adjusting a motorized 27mm ALPS potentiometer. The Destiny has 5 inputs plus a single tape loop selected by relays and indicated by LED’s.
Separating the pre-amp / power amplifier in the Destiny is controlled by a semi-hidden push switch on the rear panel and signal paths to and from the pre and power amplifier are carried by custom audio grade wiring. Loudspeaker connection is controlled locally by gold contact high current relays that can also be controlled via the Creek (CAN) bus.The Destiny can still be run with a passive pre-amp but now has the added feature of a gain selectable active pre-amp. Selection is in three steps - 3dB, 6dB & 9dB. The gain is adjustable from underneath the pre-amp selection with a 3 way slider switch. To select active or passive operation a push button on the front panel switches between the two and is indicated with an LED.A new connector arrangement can be found inside the Destiny pre-amp circuit board allowing the use of a plug-in gain Phono circuit board. Being fully isolated from the input ground, it is possible to input either MM or MC cartridges. The early range of phono boards which suit Creek’s Classic 5350SE and earlier model Creek amplifiers will not fit this new amplifier.Most types of dynamic headphones can be connected to the standard size ¼" jack socket on the front panel, for high performance reproduction.One of the more difficult tasks was to make the Destiny switch into low-current standby operation. Waking up the amplifier can now be performed simply via the Creek System Remote handset.The metal case of the Destiny amplifier is larger and more substantial in thickness and weight. The new casework design uses heavy extruded aluminum sections and turned control knobs and buttons, machined by computer aided manufacturing techniques, to achieve a very high quality finish. The front panel itself is machined from solid 10mm thick aluminum. Groups of function buttons are now clustered together within a machined circle to make it more intuitive to use. LED’s indicate the functionality. Sorbothane'TM molded feet, are also used to isolate mechanical vibration and improve sonic resolution.

EVOLUTION

To achieve 85 Watts power into an 8 Ohms load and Greater Than 160 Watts into 4 Ohms, the mains transformer has to be big. The Creek Evolution Integrated Amplifier (Evo) uses an over-rated 250VA toroidal transformer, which will provide enough current to drive the amplifier to almost double its output into 4 Ohms. To improve the sound quality, no expense has been spared.Separate windings are used for each of the high current high voltage and low voltage, analogue and digital circuits. Two sets of rectifiers and a total of 20,000 micro-Farads of multiple smoothing capacitors are used to separate the left and right circuitry and improve the dynamic performance. This is a technique used by Creek before for its up-market products and is now available in the entry-level Evolution Integrated Amplifier.(Evo) In terms of value for money, this cannot be over-stated.Generally, few Hi-Fi companies put so much effort into their product's power supplies at this price point, but Creek knows that this is an area where the rewards are high for such investment. To allow it to be easily used in different countries, the Evolution Integrated Amplifier (Evo) also uses an external voltage selector.Significantly, the Evolution Integrated Amplifier (Evo) is the first product made by Creek to use an electronic volume control. It uses a Burr-Brown PGA2311, stepped resistor attenuator operated by a microcontroller. This allows the user to adjust the volume accurately, in 1 dB steps, from 0 to -80dB. An analogue style rotary encoder, with 40mm solid control knob, is used to alter the volume from the front panel and display the reverse level in dB on a large blue coloured VFD display i.e. 80 is loudest and 0 is off. To buffer the signals in and out of the pre-amp, high grade Burr-Brown OPA2134 op-amps are used. Signal switching is performed by relays, which are driven by signal from a powerful microcontroller, similar to the Destiny amp.The Evolution Integrated Amplifier (Evo) is configured as a high open-loop gain circuit, using a double differential input and driver stage plus discrete Darlington power output stage, using high current bi-polar transistors. This is similar to the circuitry Creek used prior to its more complicated MOS-FET designs. High grade polypropylene capacitors, bypassed with large value electrolytics, are used to couple and decouple the signal into the power amp as the Evolution Integrated Amplifier (Evo) doesn't use a DC servo correction, like the Classic and Destiny amps.To keep the amplifier safe, it is monitored by discrete transistor circuitry to protect against over current demand, short circuits and DC offsets. Relays mute the input and separate the loudspeaker output in the case of faults.The Evolution Integrated Amplifier (Evo) operates conventionally with rotary controls for input selection and volume control and buttons for Tape selection and power On/off. It has four inputs plus tape - selection is via the remote handset or the input selection control. A visual indication of its status is displayed on a large blue Vacuum Fluorescent Display (VFD). The display brightness can be altered from the Evolution Integrated Amplifier (Evo) remote control handset.Gold plated input and output sockets have been chosen to provide a good connection and appearance for a product at its price point. Loudspeakers are connected with 1 set of 4mm terminal binding posts, with plastic touch proof covers. The amplifier also has a headphone socket which is becoming an increasingly rare feature of modern day amplifiers.Mains connection is via a standard, fused, IEC chassis plug. A high quality power cord, with suitable mains plug for the country of use is supplied.
