PrimaLuna has pioneered numerous technologies to redefine tube amplification. From increased reliability and tube life all the way to their unique, signature sound.
Incomparable Tube Life
PrimaLuna was founded on the idea of eliminating tube maintenance. They do this by using a true and sophisticated Adaptive AutoBias system while running tubes at the minimum dissipation (power) and giving more slam and bandwidth through superior output transformer design.
When It Comes to Bass, Power Means Nothing
It seems everybody is looking for better bass. Especially if they are replacing a tube amp that has no slam, or bass that has poor definition. So they make the mistake of buying more power. Unfortunately, power means nothing when it comes to sound quality, dynamics, and bass slam. An amp can have 200 watts per channel, but if it doesn’t have output transformers with enough bandwidth, the speakers won’t receive it. PrimaLuna is one of only a few manufacturers in the world that actually designs and winds our power and output transformers in-house.
Point to Point Wiring
You spend a lot of money on interconnects. So why have the signal go right from the RCA jacks or speaker terminals into circuit boards with copper traces so thin you can hardly see them? What’s high-end about that?
PrimaLuna employs Point to Point Wiring on all products. The entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.
What most companies call Auto Bias is actually “Cathode Bias”- A commonly used method that is cheap to make, and often found in guitar amps, but also $20,000 high-end audio amps.
An amp that has “70 watts” will typically give you only 40 watts with Cathode Bias. Most of the power goes up in heat through a single huge resistor. These amps run the tubes very hard. They need to so they can squeeze out the power. That means short tube life and failures via “shorts”.
PrimaLuna’s Adaptive AutoBias is a true, smart technology. It employs an array of sensors to monitor tubes and make adjustments seamlessly in real time. Adaptive AutoBias is completely passive and NOT in the signal path. The result is low to no maintenance, long tube life, and the lowest possible distortion for amazing sound.
