Each component is hand-built with meticulous attention to detail, resulting in a sound that is both musically engaging and technically precise, capable of driving the most demanding loudspeakers.
Riviera Labs Amplifiers
Riviera Labs Levante
The Levante offers you both class A and class A/B amplification. Don’t think because it’s an integrated amplifier that this can’t compete with separates, it does! A wonderful phono card is available to make this unit full function.
Features:
Hybrid, Zero Feedback, designed to drive any kind of loudspeakers systems.
The LEVANTE integrated amplifier has all the elements that distinguish the Riviera amplifiers (Hybrid Circuit and Zero Feedback). It has also an extra feature that makes it unique: the option to choose between pure Class A and Class AB operation. A switch on the front panel allows to select the operating class according to your preferences or needs.
In Class A mode it offers 2x30W into 8 ohms (2x60W into 4 ohms); in Class AB it offers 2x120W into 8 ohms (2x200W into 4 ohms). Note that, even in AB Class, the first 6 Watts are in Class A.

Riviera Labs APL-1
The APL1 tube line preamplifier has been designed for those who demand the best possible sound quality. Indeed, it is second only to our Reference APL01SE Preamplifier. The APL1 is the mid-priced device in the Riviera preamplifier range. Therefore, like all of our preamplifiers, it shares the same basic design choices: all-valve, Zero Feedback, and Class A audio circuitry. It is equipped with a refined double pigreco and stabilised anode power supply. In fact, there are a total of five stabilized supplies in this preamp. It also employs several design elements adopted from the Reference APL01SE preamplifier including output balance control and the use of custom output transformers that operate on both balanced and unbalanced outputs ensuring consistent and superior sound quality. The mechanical construction of this unit has been meticulously crafted, as Riviera believes it significantly impacts sound quality.

Riviera Labs AFS 32
This hybrid stereo power amplifier represents a synthesis of the key points of Riviera amplification: Zero Overall Feedback, a Hybrid design (valves for voltage amplification, solid-state devices for power), and Pure Class A operation. The AFS32 offers 2 x 32W into 8 ohms in Class A (2 x 64W into 4 ohms) and is able to drive loudspeakers with the utmost naturalness.
The voltage amplification of each channel is provided by a pure triode operating in Class A.
The amplifier is deliberately designed without current-limiting systems, making it suitable for the most complex loads.
The AFS32’s refinement and driving capabilities allow it to be used in both single-amplification and multi-amplification systems.
