What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- One of the most powerful headphone amplifiers available, providing 9 watts per channel into 50 ohms
- A massive, deep, holographic, and 3D soundstage expands headphone listening
- High-quality components, including custom-made transformers and Mundorf capacitors, lower the noise floor without using negative feedback
- Built like a tank, with oversized parts for heat dissipation, including metallic fins
- It is able to bring life into lifeless-sounding headphones
- Last bullets: Connectivity options
Product Considerations
- It is a very large and heavy unit, around 30 kg or 66 lbs
- The unit consumes 280 watts constantly and generates a lot of heat, so it needs good ventilation and is not ideal for small spaces
- The tubes have a limited lifespan, around 5,000 hours, and are expensive to replace
- It does not have a gain switch, so it can be too powerful for very sensitive IEMs, in-ear monitors, and requires careful volume adjustment
- The XLR input is not truly balanced given the circuit's single-ended nature
Comparisons (according to reviewers)
- Compared to Benchmark HPA4, the Primavera is thumpier, more impactful, and more dynamic sounding
- Compared to Enleum AMP-23R, the Primavera does dynamics better, especially with lower-sensitivity headphones, while AMP-23R is slightly faster
- Compared to Trafomatic Head 2, the Primavera offers 9W per channel, driving every possible headphone
- Compared to Riviera Audio Labs AIC10, Feliks Envy and Cayin HA-300 MKII, the amplifiers are smaller sounding
- Compared to solid-state amplifiers, the Primavera is fuller-bodied
Takeaway: The Primavera headphone amplifier is a powerful, high-end product designed to bring out the best in all headphones, with a big and impactful sound. This is recommended for those looking for a headphone amplifier that makes listening more enjoyable.

The brand new Primavera headphone amplifier from Trafomatic Audio is precisely this, a new, fresh approach for the most intimate listening, and is here to stay for all the years around.
During the immersion in the musical message, the richness of colours, the smells, the clouds, the sun, and dirt are there, all of the emotions are exposed, for our amusement.
Capable of driving even the most demanding loads, it's striking design sets the Primavera as a pure objet d'art, an icon in the rarefied world of Hi-End.
Features:
Direct coupling between stages
Implements special C-L-C anode voltage filter using Mundorf MLytic HV type electrolytic and High inductivity filter choke made by Trafomatic Audio
Completely separated power supply for each channel including main transformers
II C core oversized output transformers
The output transformers are highly sectioned with harmonically sized sections, which results in a minimum leakage inductance and the best high frequency performance
Zero feedback

Select products
Evolution Phono One
- Positioning: The entry-level model aimed at basic vinyl playback setups.
- Description: Uses an OP AMP design with separate MM and MC inputs and selectable impedance to ensure low noise performance. Compared to tube-based or high-power models in the lineup, its straightforward design suits smaller rooms and modest budgets with minimal functionality needs.
Tara 30A
- Positioning: A balanced tube preamplifier crafted for refined audio reproduction at a moderate price point.
- Description: Features Emission Labs 30A tubes, dynamic balance adjustment and an extremely low output impedance for precise channel matching. Compared to the entry-level Evolution Phono One, it adds tube warmth and detailed control, though it remains less complex than higher-powered amplifiers like EOS+ or flagship systems.
EOS+ Power Amp
- Positioning: A dual mono power amplifier engineered to deliver high power for demanding speaker systems.
- Description: Uses push-pull design with KT150 tubes and tuned negative as well as cathode feedback, resulting in well-controlled bass and a dynamic response. In contrast to preamplifiers like Tara 30A, it provides substantial power output.
Elysium
- Positioning: A flagship mono-block power amplifier built with state of the art tube circuitry for uncompromised sound quality.
- Description: Uses pure Class A circuits with Eimac 250TL output tubes and a unique direct-coupled transformer setup to extract every subtle detail. Compared to the EOS+ Power Amp which focuses on power output, it offers a more refined sonic character.
Rhapsody
- Positioning: An integrated amplifier representing the highest achievement in valve amplifier design.
- Description: Features 300B valves in a parallel single-ended Class A configuration to produce natural tonality and rich coloration with unified performance. Compared to standalone preamplifiers or power amplifiers, its all-in-one design delivers exceptional technical sophistication.
