Sonic Nirvana Comes From Gentle Nudges...

At PrimaLuna, we have the experience to know that there is no product that is “perfect” for everybody. That’s why we have our exclusive Adaptive AutoBias that allows the customer to fine-tune the sound of any PrimaLuna amp by changing to a HUGE number of different tubes, with absolutely no need for the tubes to be matched, or biasing once you put them in.
