PrimaLuna EVO 300 Hybrid Integrated Amplifier
Our first PrimaLuna Hybrid Integrated Amplifier comes with a PrimaLuna designed tube pre-stage section and a Floyd Mosfet power stage. Durob’s Jan de Groot designs the latter. Mosfets are the closest in solid-state to tubes and a logical choice for expanding a tube-based only range. Jan has been designing with Mosfets as a profession since 1995. PrimaLuna was established in 2003.
The Primaluna pre-stage uses our well known six pieces 12AU7 configuration. The Floyd Mosfet power stage uses paired Linear Systems JFETs and 20N20/20P20 Mosfets resulting in a 2 x 100 Watt power rating at 8 Ohm.
Where possible, we use hard wiring, and if PCBs are needed, we use the highest quality PCBs available (2.5mm thick instead of the standard 1.6mm), 105um (usually 35um) gold plated copper tracks.
The PrimaLuna pre-stage uses two power supplies (including two separate transformers), while the power stage comes with a single 500VA transformer. The starting point for all the power supplies is our AC Offset Killer circuit.
The amplifier comes with six inputs (5 x Line RCA, 1 x HT) and outputs (tape out, stereo/mono sub, headphone and speakers, of course). It arrives with a fully shielded heavy-metal sub-chassis for the optional MM phono stage.
Construction is extremely solid and robust, as usual, and puts 25kg net on the scale, while the looks are elegant for such a heavy amplifier. Lean & Mean!
In all PrimaLuna products, we use high-quality parts and wiring for the best sonic results and the highest reliability. Takman, DuRoch, Nichicon, Alps, Linear Systems, Rubycon, Kemet are some of the brands we use.
First comments from audio professionals from all over the world are coming in now and sound good! Production is running, and at the end of the year, early next year, we hope to have sufficient stocks around the world, despite the global lack of various electronic components.
