Norma Revo IPA-140 Integrated Amplifier

£5,695.00

Brand Norma

The Norma Revo IPA140 integrated amplifier represents a definitive choice for amplification. Its high power (140W/8Ohm) and the ability to drive the most demanding speakers, make it an extremely versatile amp. Versatility is enhanced by the ability to customize the input / output connections and to insert the Phono MM / MC board. The elegant and sophisticated style is perfectly in tune with its sound personality. Power, dynamics, speed and transparency are combined to create outstanding musicality and a total absence of listening fatigue. The inside workings show that the technical refinement follows the same philosophy. The Revo IPA-140 uses a proprietary circuitry, regulated high-speed power, low noise and is built with a careful selection of the best materials available.

Norma is based in Cremona Italy, a place where music has always played an important role. Cremona is the home of Monteverdi, Ponchielli, Stradivari, Amati and many other artists. For more than 20 years Norma has been involved in the study and implementation of sophisticated audio amplifiers. Technical skill and musical sensitivity must be merged together, in the same way in which the best musical instruments are made. In Norma we are convinced that the influence of audio electronics on the outcome of audio reproduction is much greater than commonly assumed. Listening to a NORMA product can express this concept, better than words, closer than ever to live listening. The sound of Norma products is unique, represents a synthesis of parameters which often conflict with each other. Dynamics, speed, and absolute transparency are combined with extraordinary musicality and a total lack of listening fatigue. The conflicts between solid state and valves are finally overcome, leaving space only for pure listening pleasure

The optional Phono board PH-2 for the REVO IPA-140 amplifier adds to the device the functions of impedance matcher, RIAA equalizer and preamplifier, to receive a signal from a turntable.
It has the peculiar characteristic, and probably unique in its genre, to be made in dual-mono layout: the two channels are placed on two independent boards, and the power supply is separately stabilized and filtered, to deliver the best possible quality.
It’s able to receive signal from MC (Moving Coil) and MM (Moving Magnet) turntables, simply by replacing an integrated circuit (provided as standard). 
It’s possible to vary the load seen by the head by moving a switch, that commutates between 4 standard resistance values (100,500, 1K, 47 Kohm) and a user-definable value, which can be chosen by inserting a resistor.
The gain value is variable with a similar system, with a range that goes from 34 dB to 52 dB in six steps, plus a value definable by the user, again just by inserting a resistor.
 The PH-2board is made with very-low-noise components, which are able to handle turntables with a robust output, and also work perfectly with heads that have a lower sensibility.
With its very accurate layout, that makes the setting operations very simple, this board will let you appreciate at best the expressive nuances of an analog source, without compromising its natural character.

The USB-1 option for the REVO IPA-140 amplifier consists in two independent boards, mounted in a “sandwich” configuration. One contains the digital and filtering stage, the other the analog filtering and output stages. 
This board must not be considered as a mere addition of a digital input, but as a high quality solution, able to compete with the best converters on the market.
Plus, since it’s installed inside the amplifier, it eliminates the need of an interconnection cable which, if high quality, would cost far more than the USB option itself, and maybe even more than the external DAC.
 The USB receiver is a Tenor TE8802L, which can support frequencies up to 192 KHz, both in synchronous and asynchronous mode. On Apple systems, it requires no driver installation.
The Digital-to-Analog converter used is the Wolfson WM8741, one of the most modern and appreciated DACs, which can work at up to 24 bit and 192 KHz (with internal 32 bit calculations).
 The digital board has 3 independent tension regulators, plus a local high-stability and low phase-noise oscillator.
Three different digital filters can be selected just by connecting the jumper on the board, to obtain different temporal and phase responses.
 A particular effort has been put in the analogue section: in fact, thanks to a proprietary solution, just one active stage is on the signal path, to minimize the influence on sonic performance.
 The board can be easily installed in the device, at any moment.
