AC Offset Killer

Along with dual toroidal power transformers, PrimaLuna designed the AC Offset Killer to lower tranformer noise like no other. The sense of space and texture will amaze you, as the resonance of an acoustic guitar string seems to trail on forever.

Remote Controlled Triode/Ultra-Linear Switching

Triode and Single Ended Triode (SET) amps have warmer and fuller sound, but ultra-linear has more extension on the top and bottom (and greater power). With a bigger difference between loud and soft, ultra-linear is great for modern music, but triode is better for harsh and brittle music from years past. PrimaLuna has designed a remote control that allows you to change from triode to ultra-linear and back again without getting up. Make an instant comparison to find the best listening environment for your favourite song.

Custom Toroidal Power Transformer

There are two types of noise generated by power transformers; magnetic and acoustic, which is why the best audio products use toroidal power transformers which radiate 1/10 of the magnetic field that standard transformers produce, reducing the amount of details obscured. The absence of an air gap also means that toroids have an acoustic noise reduction of 8:1 which doesn't come cheap, but PrimaLuna doesn't cut corners. All PrimaLuna products use toroidal transformers enclosed in a metal housing and potted in a non-microscopic resin to reduce noise further. This housing also protects from moisture and deterioration for years to come.
