Tube-Hybrid POWER

EVO 300 Hybrid Poweramp
$7,195 Stereo / $14,390 Monoblock Pair

PrimaLuna’s hybrid design approach uses unique and innovative engineering to tightly connect the tube and the MOSFET section, ensuring they are always working in tandem.

The Hybrid Power Amplifier uses the same tube input gain-stage and solid-state power amp gain-stage as the celebrated Hybrid Integrated, except that the power amp’s solid-state circuit has a gain relay which allows for gain switching between 24 dB or 30 dB, while keeping the tube gain steady.

Too often, hybrid amps turn out to be less than the sum of their parts – a mismatch, both technically and sonically. It's essential to choose solid-state components that behave similarly to a tube. PrimaLuna EVO 300 Hybrid Power Amplifier's MOSFETs, used in the power stages, share similar characteristics with tubes.

Floyd Design's Jan de Groot has created amps with MOSFETs for 26 years. These MOSFETs are specifically designed to pair with our most successful PrimaLuna pre-stages, matched for the best sound quality possible and mounted it in one chassis;  Et voilà!

The PrimaLuna EVO 300 Hybrid Power Amplifier is unlike any other hybrid amplifier on the market. You can SEE that, and you can HEAR that. We wanted the BEST HYBRID possible, and we knew it would become a more expensive unit. After the final fine-tuning and listening tests, we can easily accept and justify that!

Tube in the Front, Solid State in the Back

The input stages of the EVO 300 Hybrid use two 12AU7 tubes in the gain stages, and four 12AU7 driver tubes. The doubled driver tubes ensure a lower impedance on the output stages, allowing for large dynamics, a huge soundstage, and lots of beautiful harmonics and texture.

The solid-state output stages use cascading JFETs from Linear Systems and each channel boasts two complementary pairs of MOSFETs from Exicon. These MOSFETS are exotic and custom-designed and built and are not available to anyone else! The setup is calibrated to offer the lowest impedance, and the 100 W into 8 ohms (160 W into 4 ohms) power sounds massive, allowing this amp to preserve tube glory while offering the excellent grip, low-bass power and control that MOSFETs are known for.

The most crucial capacitors, the ones in the signal path, are extremely expensive tin-foil caps that are made in Europe. Elsewhere, even the caps outside the signal path are the top-quality models that modders use to upgrade their regular amps!

Stereo or Monoblock operation

It's as simple as flipping a switch, and PrimaLuna EVO Poweramps instantly switch from stereo to monoblock operation! Buy one, and as your budget grows your system can grow too. The benefit of monoblock operation is the amp now has dual output transformers for the best coupling with your speakers, and the addition of a 2-ohm speaker tap added to the 4 and 8-ohm taps. While all PrimaLuna amps are made for ribbons like Magnaplanars and electrostatics like Martin-Logan, you haven't heard anything until you have heard a PrimaLuna monoblock!

CUSTOM TOROIDAL POWER TRANSFORMERS

Power transformers generate two types of noise, magnetic and acoustic. That's why toroidal power transformers are used in the very best audio products. Compared to standard transformers, toroids radiate about 1/10 the magnetic field that pollutes music and obscures detail. Additionally, the absence of an air gap typically means toroids have an 8:1 reduction of acoustic noise. As transformers are the most expensive components in any audio product, manufacturers will even house cheaper C-core and EI-core transformers in an outboard power supply box with an umbilical cable rather than upgrade to an expensive toroid. The increased cost is significant, but PrimaLuna doesn’t cut corners. All PrimaLuna products use massive, potted toroidal transformers. PrimaLuna transformers are enclosed in a metal housing and then potted in a non-microphonic resin to further reduce noise and to protect the windings from moisture and deterioration forever.
