Philosophy

Most integrated amplifiers combine the functions of volume control, source selection and amplification in single multi-function circuit. Not so the soulution 330 Integrated amplifier. It takes the uncompromising route of separate circuits, combining a dedicated preamplifier, and a dedicated power amplifier in one housing. It is a real soulution product – truly a great amplifier.

Design

The audio section of the 330 is physically separated from the power supply and digital circuits. In order to reduce interferences to a minimum, these sections are additionally shielded. The power amplifier section as well as its dedicated power supplies are executed in dual-mono layout for optimal channel separation (> 105 dB) which is key for a three dimensional sound stage.

Amplification

The amplification circuit of the 330 is based on the technology used in our Series 5 amplifiers. Current amplification is done in three stages, each with a narrow, almost linear operating range. The high Class A operation supplemented by more than 160,000 µF of storage capacitance results in a nearly infinite impulse response. High-precision idle current management ensures optimal Class A operation for all conditions, without requiring any readjustment in the music signal. Optimal sound is thereby guaranteed immediately from switch on. Control circuits that protect against RF or DC signals at the input, and short circuits at the output ensure safe operation in all situations.

Power supply

A total of six power supplies – optimized for each function – feed the 330 integrated amplifier. Four cutting-edge switched-mode power supplies deliver 1,200 VA of audiophile quality power. They feature high performance filtering at the input and output, and high speed soulution voltage regulators to deliver considerably more stable power than any conventional, transformer-based technology.

Volume control

The 330’s volume control uses only high-precision, low-noise metal foil resistors, and it controls both the volume and balance. To block switching peaks during volume changes which may be hazardous to power amps, the 330 is equipped with a second volume control with PGA (Programmable Gain Amplifier). Active only during the volume control process, it is similar to a potentiometer and enables the volume to be adjusted smoothly without clicks. As soon as the new desired level value has been selected, the unit returns control to the precision resistors.

Theatre mode

Theater mode allows users to optimally integrate the 330 with AV systems. In theatre mode, the input signal by-passes the preamplifier section without any adjustment for volume or balance.

Operation

The 330 integrated amplifier is operated via its three front panel buttons and rotary control. Multi-functional, these allow optimisation of the entire audio system, and an ideal set-up of the individual components. All operating modes are indicated on the clear display.

Philosophy

A CD or SACD player brings both digital and analogue domains into an audio system. For the very highest quality sound every part of the player is critical. A high-quality D/A converter alone is no longer enough. The 746 unites a top quality optical drive, a super-precise master clock generator, an intelligent digital signal processor with over­sampling, and analogue output stages of the utmost quality. Together they ensure nothing in the music is lost on its way from disc to output connection.

Design

As with its Series 7 sibling the 560 D/A-Converter is packed with cutting-edge tech­nology with one objective – the love of music. The parallels include a consistent dual mono design in the output stages and separate power supplies for digital elec­tronics and the analogue stages. The 560 D/A-Converter adds a digital volume control that allows direct connec­tion to a power amplifier.

D/A conversion

Burr-Brown devices perform D/A conversion only. Their internal upsampling and filter stages are not used. The output currents are converted to voltage and then filtered. With an internal bandwidth of 40 MHz, this current/voltage conversion stage allows best signal-to-noise performance and maximum dynamics in the analogue domain.
