What's your approach to customer support?
Riviera, as many other producer have a network of service centers directly connected with our local distributor. In Europe, we mostly take care of possible issues directly, because it is cheaper and faster than shipping the products to a service, than shipping part to the service and the unit back to the customer. So the customer only have to return the unit to the dealer where they bought the unit.

Rhapsody is the pinnacle of our decades of experience in developing State of the art valve amplifiers. The name itself is the expression of our devotion to the Music and the Art. By definition it implicates the profound roots and legacy to the ancient Greek Art of the rhapsodists in performing Epics, to the most modern compositions, where the one-movement work structure of highly contrasted moods, colours and tonality, is expansive and yet unified in structure. The 300B valves are a piece of great audio history that are represented in the Rhapsody in the best and most refined way. The naturalness, the drive, their tonality and rich colour pallets are unmistakable. All of those virtues are combined and moved a step further by Trafomatic dedication into the deep understanding of the cyrcuit. The result is a endlessness adventure in discovering undisclosed hidden places in your favorite recordings.

Our take on the brand
The 032 Integrated Amplifier offers a wide variety of connectivity that far exceeds the normal range of integrated amplifiers. A PRE OUT output, for example, allows the connection of a separate power amplifier or the central volume control of different listening zones within a multi-room application. With its mighty 650 VA power supply the 032 Integrated Amplifier effortlessly delivers continuous high current in order to perfectly control even large speakers with low impedance and complex loads. Excellent special resolution and musicality are the hallmarks of the 032.
Product Strengths
- Music is delivered without perturbation, showcasing a 'grip' on the music
- A beautiful sonic palette is present, with a warm, detailed bass and very smooth, detailed highs
- Understated approach to music replay is pure and precise, without coarseness or grain
- Fabulously well made, with impressive build and finish
- Volume control has a hefty, well-damped but very precise feel to it, and the amplifier's on-board software is quick to respond
Product Considerations
- The headphone output is hidden on the rear panel, making it inconvenient to connect
- Large and heavy (around 40kg), requiring sturdy equipment support and assistance when unpacking
- The combination of heatsinks all-round and reflective chrome front panel may not be to all tastes
- Highly transparent sources and speakers are required to get the best performance
Takeaway: The Burmester 032 integrated amplifier sounds exceptional with refined sound and impressive insight. If the system is talented, this amplifier could be a great match.

Our take on the brand
Our Summary
Product Strengths
- New patented design SCS (source current steering) allows the amplifier to have a fabulous bottom end without affecting the glorious midrange
- Proprietary noise reduction system eliminates noise that can be inherent in a single-ended design
- Circuit protects the 300Bs and keeps them in their safe operating range, so there is no chance of damaging the tube or having a shortened life
- More power from this amp than a traditional 300B, it's the difference in presentation
- It has Bluetooth, phono stage (moving coil and moving magnet), and wireless remote control
Product Considerations
- Instructions could be a little clearer about installing the 300Bs
- More warm-up is needed for each listening session than originally allowed
- The 91E was designed for operation with Western Electric manufactured 300B electron tubes
- The brands and specifications of the capacitors, resistors, transformers, internal wires, RCA jacks, switches, and binding posts are not disclosed
Comparisons (according to reviewers)

Our take on the brand
Our Summary
Product Strengths
- Wonderful mid-band presentation that comes from the 300B tubes
- Bass is extended and controlled
- Provides detail and insight into recordings without being piercing
- Soundstaging is wide, deep, and natural sounding
- Every stage in the amplifier has its own power supply, and particular care has been taken with the 300Bs themselves
Product Considerations
- The included remote is functional, but not in keeping with the quality of the amplifier itself
- It is very heavy, weighing 40kg
- The high polished chrome and gold accents may divide opinion
- Those looking for an amplifier that is absolutely neutral in its presentation may want to listen to something else
Comparisons (according to reviewers)
- Vs Merrill Thor amps, the Jadis I300, to the reviewer's ears, is a far superior amp for listening and putting a big grin on your face
Takeaway: The Jadis i300 is built superbly and delivers a balanced sound with detail and emotional connection, making it a joy to listen to. It is a refined performer across the audio spectrum and with all kinds of music.

Our take on the brand
Our Summary
Product Strengths
- Beautifully crafted with Italian manufacturing traditions integrating form with style
- Offers a warm and balanced mid-range, a fulsome projection, and reproduces authentic resonance
- Macrodynamics are represented with a clear, yet golden glow typical of SET amps—but with a bonus from the 211 power tubes
- Creates a substantially open and spacious soundstage, augmenting the perception of depth and instrument placement
- Renders the graininess of the violas and the cellos beautifully, which sounds natural and musical
Product Considerations
- The expense of replacing tubes is a serious concern
- SET amps require speakers of very high sensitivity (93dBs and above)
- The bass is perhaps slightly muddied in spots
Takeaway: The Tektron Italia Neptune is a sophisticated Italian-made amplifier where design and function follow the higher spirit of beauty and style. The engineering offers the best of 'tube' consciousness and listening experience.
Video review
Our take on the brand
Our Summary
Product Strengths
- A variety of tubes can be used (45, 2A3, PX4, PX25, 300B, or 300B XLS) to produce different power outputs (1.5 to 22wpc)
- It can operate in single-ended (SE) or parallel single-ended (parallel SE) mode
- It is very adaptable—allowing for changes to input tubes and 5AR4 rectifiers to alter the amp's sound
- Built-in bias meters and pots allow for re-biasing when changing tubes
Product Considerations
- The right speaker load (high output impedance) is needed to perform optimally
- Single-ended amps shun negative feedback, which would lower their output resistance
- Speakers not well-suited for high output impedance amps may experience premature bass roll-off and a rising presence response
Takeaway: The TK2A3/300PSES-i Ref amplifier offers a lot of flexibility for tube rolling and sound customization. It is well-suited for high-efficiency speakers.
