PrimaLuna EVO 100 Integrated amplifier
Compare PrimaLuna construction to any other brand, at any price. You’ll be amazed.
BAD TUBE INDICATOR
PrimaLuna engineers wanted to make owning a tube amp so simple you would have no excuse not to have your tube dreams come true.
If a tube fails, Adaptive AutoBias will instantly put the amplifier into protection mode so no parts can get damaged.
A red LED will light up in front of the tube that needs replacing.
Simply plug in another tube, and listen.
CUSTOM TOROIDAL POWER TRANSFORMER
Power transformers generate two types of noise, magnetic and acoustic.
That’s why toroidal power transformers are used in the very best audio products.
Compared to standard transformers, toroids radiate about 1/10 the magnetic field thatpollutes music andobscures detail.
Additionally, the absence of an air gap typically means toroids have an 8:1 reduction of acoustic noise.
As transformers are the most expensive components in any audio product, manufacturers will even house cheaper C-core and EI-core transformers in an outboard power supply box with an umbilical cable rather than upgrade to an expensive toroid.
The increased cost is significant, but PrimaLuna does not cut corners.
All PrimaLuna EVO 100 Integrated use massive, potted toroidal transformers. PrimaLuna transformers are enclosed in a metal housing and then potted in a non-microphonic resin to further reduce noise and to protect the windings from moisture and deterioration forever.
CUSTOM SUPER-WIDE-BANDWIDTH OUTPUT TRANSFORMERS
Output transformers are the most important part of any tube amp.
They determine how low the bass will reach and how high the top end goes. 250 watts of power will have no top and bottom extension if the output transformers don’t have the bandwidth.
They use lower power to extend tube life, and bandwidth to give you slam.
Transformers are the most expensive components in an amplifier, so manufacturers save money by using ‘off the shelf’ units available on the market.
PrimaLuna output transformers are custom-designed, wound in-house.
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 high end audio amps.
It reduces the available power of the amp and runs the tubes hard, meaning shorter tube life and failures via “shorts”.
PrimaLuna’s Adaptive AutoBias is a true, smart technology employing an array of sensors to monitor tubes and make adjustments seamlessly in real time.
More important, it is the ONLY circuit of its kind that is truly “adaptive” by addressing “tube pinch off” at higher volumes, therefore reducing distortion by over 50% and greatly extending tube life.
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.
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.
PrimaLuna EVO 100 Integrated 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.
SMARTWATTS – EXTENDED TUBE LIFE
Tube life is simply a matter of how hard you run the tubes. That’s it.
The only way to extend tube life is to run them as close to zero as you possible can, making sure it is not so low you go into crossover distortion.
The life of a tube will depend on two things: Plate and screen voltage.
If the plate and screen voltage is high, you are more likely to get tube shorts when you turn the amp on and you get cathode stripping which greatly effects the cathodes ability to spit out electrons.
PrimaLuna runs their output tubes at a minimum dissipation without going into crossover distortion.
When you look at their amps, they provide less power from each tube.
With KT-120’s as an example, a PrimaLuna will give you only 21 watts per tube.
So running a pair of them you get 42 watts. That’s a lot of power, but the demands per tube are a fraction of some manufacturers that give you 100 watts from a pair of KT-120’s.
It’s a cheap way to get big power, and it’s cheap. In fact, free.
To get more power the right way is expensive.
It requires bigger transformers, sockets, wiring, resistors, capacitors, and the tubes to do it.
Which is exactly what PrimaLuna do.
But they do not stop there.
Read this carefully: Power has nothing to do with sound quality.
Or bass slam. You can buy a 200 watt receiver for £500.00, and it will even have surround sound.
Do you think for a minute it will sound better than a 50 or 100 watts high end amp costing £7000.00?
Of course not. Only first-time buyers think that way.
Experienced audiophiles know that for the majority of listening sessions, you use maybe 10 watts of power.
Their AMPS ARE PERFECT. BUT YOUR SYSTEM MAY NOT BE
Ask any seasoned tube-head what the most musical output tube is and they will most certainly declare it the EL34.
Other amp manufacturers would love to use it.
Only PrimaLuna, through their proprietary output transformer designs, can give you EL34 midrange beauty with top-end air that goes on forever.
And, bass extension with so much slam, our amps are used to power subwoofers.
However, every system is different.
What if you bought a speaker with bass that overloads the room? Or, that is too dark? Or, too bright?
What if you just want to have fun trying the different type of sound from a vast pallet of tubes?
With PrimaLuna, you get to choose.
Go for it. 6L6G, 6L6GC, 7581A, EL34, EL37, 6550, KT66, KT77, KT88, KT90, KT120.
A future-proof design, PrimaLuna is compatible with NEW tube types not even thought of today!
