PrimaLuna EVO 400 Tube Poweramplifier
PrimaLuna products please the senses long before you plug them in. All models feature handmade construction, and the heavy-gauge, fully vented steel chassis has a five-coat finish, each coat hand-rubbed and polished. Inside, you will find point-to-point wiring with only the best Swiss silver wires – a level of detail that is usually only available (and not always!) in the most expensive tube equipment.There are no cheap plastic remotes here. PrimaLuna uses heavy metal remotes that are substantial, yet still elegant and ergonomic.
Talking about heavy metal, try lifting a PrimaLuna to see just how much we put into them. All PrimaLuna models feature custom-designed toroidal and EI-frame transformers, made to the exacting spec of one of the most prestigious transformer designers in the US. Each transformer is fully encapsulated for the lowest hum and best isolation, and offers huge output bandwidth and speaker control. There is no cheap or lightweight way to do this, and this is why PrimaLuna is famous for combining the midrange magic of tubes with sparkling highs and deep, solid bass.
