The PrimaLuna EVO400 Preamplifier is a high-end, dual-mono linestage. Forget the budget price. It’s simply one of the best linestages we offer.

Key features of the EVO400 Preamplifier are:

  • Low distortion, low noise, high bandwidth circuitry, using full dual-mono design,  six 12AU7 valves (widely available in new old stock versions), two 5AR4 rectifier valves, and custom-designed toroidal transformers.
  • SuperQuiet line inputs and ALPS Blue Velvet motorised volume control for ultra quiet operation, and ultra realistic reproduction of music.
  • TAKMAN resistors, DuRoch tinfoil capacitors and other highest-quality internal passive components.
  • SmartGain Design, with only 10 dB gain specification for ultra-quiet operation, even with high-sensitivity speakers.
  • Tube (valve) rectification, using two 5AR4 rectifier tubes for pure, dual-mono, all-tube design.
  • Point to point wiring using Swiss-made, silver-plated, oxygen-free continuous crystal copper with a Teflon dielectric in the critical signal path. The EVO400 is a work of art with internal construction. Assembled by artisans, it will last a lifetime.
  • Chassis made of finely finished heavy gauge steel with automotive quality finish. Removable tube cage included.

Three sets of stereo RCA inputs, two sets of stereo XLR inputs, and one set of home cinema pass-through inputs. One set of stereo RCA outputs, one set of stereo XLR outputs, and one set of RCA tape outputs. A full-function metal remote control is included.
