Усилители для наушников — Trafomatic Audio Primavera

The Primavera is a flagship headphone amplifier from Trafomatic Audio, built as a no-compromise Direct-Heated Triode Class A design handcrafted in Serbia. Trafomatic Audio has built a considerable reputation extending from its flagship six-figure Elysium power amplifiers, and the Primavera represents the brand's ultimate current expression of tube amplification applied specifically to headphones.

Key specs that matter

XLR and RCA inputs are provided, with input sensitivity of 0.5Veff and input impedance of 47K ohms. The tube complement is one 6S45P driving tube and one Svetlana SV 811-10 output tube per channel, operating in pure single-ended Class A with zero negative feedback. Selectable headphone output impedances span 25, 50, 100, 300 and 600 ohms, covering essentially any headphone load. Gain is 33dB, with maximum output power of 9W into 50 ohms - substantial for a tube headphone amplifier, sufficient to drive even the most demanding planar magnetic designs like the HIFIMAN Susvara and Abyss AB-1266 with real authority. Frequency bandwidth is 10Hz (-1dB) to 80kHz (-3dB) for both headphone and line outputs, with signal-to-noise at 88dB. Distortion is 0.2% at 0.5W/1kHz. Headphone outputs include a Neutrik 4-pin balanced connector, a quarter-inch Neutrik connector, and two 3-pin balanced Neutrik connectors. At 340 x 480 x 240mm and 30kg, this is an exceptionally substantial chassis for a headphone amplifier, using completely separate dual-mono power supplies per channel, custom C-core output transformers, and a special C-L-C anode voltage filter with Mundorf MLytic HV electrolytic capacitors and Trafomatic's own high-inductivity filter chokes.

Sound and use context

Expect an effortlessly natural, spacious and dynamically alive presentation - a holographic soundstage, rich harmonic textures, deep and controlled bass, and vocals that bloom with lifelike presence, combining classic tube impulse speed and spatial imaging with transistor-amplifier-level dynamic authority.

Pairing

The selectable 25-600 ohm output impedance range and substantial 9W output mean this amplifier drives virtually any headphone, including the most demanding high-impedance or low-sensitivity planar magnetic designs, without strain.

Alternatives

Trafomatic Audio's Head 2, a Class-A push-pull design following the earlier Experience model, sits as a more accessible alternative within the brand's headphone amplifier range, worth considering instead if the Primavera's considerable price and scale exceed what a specific system requires.
