Don't buy good. Buy perfect. Iconic. State of the art. Something that will still be relevant ten years from now and that is built to last a lifetime. 

DiaLogue Premium Integrated - $3399

 
 

Thinking of buying an amp because of good reviews? Every product, no matter what, gets good reviews. So how do you know if it's simply good or world-class? 

The answer is simple- When a magazine reviewer spends their own money to buy it for themselves! Many reviewers have done just that because every PrimaLuna reviewed has a Stereophile Class A rating. Class A is defined as "Best attainable sound for a component of it's kind, almost without practical considerations" with practical considerations meaning at any price. The Absolute Sound's Dick Olsher is possibly the most experienced and technically adept writer on staff when it comes to tube amplification. He declared "It is my current benchmark in integrated tube amplifiers," resulting in a 2014 Editor's Choice Award. 

Sure it looks good. But that should never be a reason to buy. Don't be fooled by overpriced name brands and lofty descriptions that cover up mediocre build quality. Do you want an $8000 integrated amp weighing only 36lbs with one printed circuit board, no-name parts inside, and a push button chip volume control? Or a $3399 integrated weighing 64lbs, hand made with Swiss point to point wiring and the finest exotic parts, and the most advanced technology found in any tube amplifier? Any audiophile who is also an electrical engineer would know instantly.

REMOTE CONTROLLED TRIODE/ULTRA-LINEAR SWITCHING

Do you have some classic rock albums you used to love so much that have now ended up left on the shelf, un-played for years? How about jazz or classical recordings from the 60’s? Every audiophile has albums that they used to play, but stopped because they are harsh, brittle, or bright. There is a solution.

Triode and Single Ended Triode (SET) amps are popular for their warmer, fuller, and easy to settle into sound. But triode amps have limitations! Ultra-linear has more extension on the top and bottom, not to mention greater power. They have greater “pop” with a bigger difference between light and dark, and loud and soft. Having triode only is VERY limiting.

The best option is to have both triode and ultra-linear. PrimaLuna engineers in Holland designed an ingenious circuit that lets you change from triode to ultra-linear with a push of a button on the supplied remote control. No need to get up and stop the music. Make an instant comparison while you listen and choose what you like best for that song or album.

AC OFFSET KILLER - A PRIMALUNA EXCLUSIVE

DiaLogue Premium is about goose bumps. The ones you get when music comes out of a background so quiet, you may say to yourself “Just how is this possible?” PrimaLuna custom-winds our own massive toroidal power transformers that are low in hum and EMI. But we wanted more. Our engineers designed the AC Offset Killer to lower transformer noise to a place no other manufacturer dreams of going, regardless of how bad your electricity is. The result? Sense of space. Texture. The resonance of an acoustic guitar or violin string that seems to trail on forever. The AC Offset Killer will amaze you.  

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. No guessworkNo smoking ampNo getting out the soldering iron or dropping your amp off at UPS

TAKMAN RESISTORS

If you bought a lesser amplifier, you would pay hundreds to make this upgrade. Easy to identify through their pink color, these premium resistors from Japan are popular with those who rebuild and upgrade their gear. "Modders" love TAKMAN for their low noise, linearity, and musicality.

SCR TINFOIL CAPACITORS

Made in France, these capacitors are used in the critical signal paths and while they are expensive, the PrimaLuna team felt they could not be left out after careful listening comparisons with many different types.

DIALOGUE CLASS POWER TRANSFORMERS

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 that pollutes music and obscures 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 doesn’t cut corners. All PrimaLuna products 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.

DIALOGUE CLASS 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. We 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, and massive. Our DiaLogue Class components feature the largest, widest-bandwidth output transformers we’ve ever made. One reason why no other brand sounds like a PrimaLuna. "The flat tops and bottoms of these squarewaves correlate with the amplifier's extended low-frequency response; PrimaLuna's output transformers are of excellent quality." -John Atkinson, Stereophile Magazine

SuperQuiet Line Inputs

Input selector switches leak noise and signals from other sources, as they never turn off the other inputs completely. And, they deteriorate with age, requiring the use of cleaners. Many are mounted on the front panel requiring long runs of wires to the back panel inputs. These wires pick up stray noise from RF and EMI.

PrimaLuna has a better way. Instead of a switch, input selection is done using premium quality sealed relays mounted in the rear where you plug in your components. When an input is selected, that relay closes giving you the best connection possible. All the other relays are left open, so noise and signals from other sources can’t leak in. The signal path is now almost non-existent, so there are no wires to pick up noise.

ADAPTIVE AUTOBIAS

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. 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.

Adaptive AutoBias also provides unparalleled flexibility by allowing use of almost any tube on the market today. It even has a fine-tuning switch for EL-34 and KT88/KT120/KT150 tube types.

POINT TO POINT WIRING W/ Swiss Made Wire

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.

DiaLogue Premium models use Swiss-made, silver-plated, oxygen-free continuous crystal (OCC) copper with a Teflon dielectric in the critical signal path for superior signal speed and increased clarity.

 

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. Manufacturers that run the hell out of tubes to pump up their power ratings will never tell you what voltages they use. They’ll say it’s “proprietary” as if it’s some secret sauce. There is no such thing. But if they told you that they used 575, 600, or even 625 volts you probably wouldn’t buy. We proudly tell you our tubes run at just about 417 volts for the plates and screens.

PrimaLuna runs their output tubes at a minimum dissipation without going into crossover distortion. When you look at our 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 did. But we didn’t stop there.

Read this carefully: Power has nothing to do with sound quality. Or bass slam. You can buy a 200 watt receiver for $299, 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 $10,000? 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.

 


OUR 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 our 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 colors of sound from a vast pallet of tubes? With other manufacturers' products, you're stuck. They're a one-trick pony. How are you going to fine-tune your sound? Buy some different cables?!

With PrimaLuna, you get to choose. Go for it. 6L6G, 6L6GC, 7581A, EL34, EL37, 6550, KT66, KT77, KT88, KT90, KT120, even the monstrous KT150. A future-proof design, PrimaLuna is compatible with NEW tube types not even thought of today!

Headphone Amplifier
One of the best headphone amps in the world. Most tube integrated amps and preamps use a solid state op-amp chip for running headphones. Stand alone tube headphone amps will vary in quality like any other tube amp. Headphones are simply small speakers that require less power. Some will use smaller output tubes that groan to have enough dissipation to run power-hungry planar headphones. Other brands, including those costing $5,000 or more like Mal Valve, will use larger output tubes, then use a voltage divider network to drop the power down to an acceptable level for headphones. This is how PrimaLuna designed the HP. We simply took advantage of the fact that this is the best tube integrated amplifier. Now you don't have to pay for a separate state of the art headphone amp. Unlike the other brands, the HP can even run your headphones in Triode or Ultra-linear operation at the push of a button!
