Riviera Audio Labs

The amplification stages in the Riviera Audio Labs APL1 operate in pure class A. Riviera Audio Labs APL1 uses a more powerful power transformer and a capacitor block of the power supply filter. The preamplifier also uses an input transformer circuit for both types of inputs.

The Revival AIC10Bal is a hybrid balanced integrated 2X10W headphone amplifier, Class A, without feedback, with XLR and RCA inputs.

The Riviera Audio AFM70 operates in Class A and is capable of delivering 70 watts of power when operating on a load with a nominal resistance of 8 ohms. The pre-stage of the monoblock uses a vacuum lamp, and the output stage is built on semiconductors. Thus, a hybrid concept is implemented in the Riviera Audio AFM70.

The Riviera Audio APL01 Special Edition preamp, according to the developers, represents the ultimate expression of Riviera's preamp expertise. Every aspect of the design has been carefully optimized so that musical qualities are more important than technical specifications alone. The component is fully tube-based and uses a Class A configuration without Zero Feedback, providing exceptional musicality and impressive technical performance.

The Riviera Audio AFM100 Special Edition Power Amplifier is a Class A reference monoblock amplifier that combines all the key values of Riviera amplifiers. The AFM100SE amplifier also operates without feedback, has a hybrid architecture (lamps for voltage amplification, semiconductors for power) and a pure Class A mode. The novelty provides a power of 100 watts when operating on a load with a nominal resistance of 8 ohms in class A (200 watts for 4 ohms) and is able to control acoustic systems with the highest possible reliability.
