Prima Luna DiaLogue Premium Preamplifier

These are the words of Dick Olsher, one of the world’s leading audio critics and tube audio experts, who for decades has written not only reviews but technical articles on high fidelity.  Here’s a dirty little secret: Preamps have become a high-profit center for manufacturers. They won’t like that we tell you this, but it’s true. Power amps are expensive because they require big power and output transformers, which are the single biggest cost in building anything. An overpriced preamp is cheap to make, but first make sure it has a big box and pretty face plate. Then add one little transformer (not even toroidal!) that costs a few bucks, a tube or two mounted on a printed circuit board, a $5.00 chip as a volume control. Next, make up some lofty story about the design that has nothing to do with substance, and you’re done. How does anybody justify charging $10,000 for box of average parts that weighs 13 lbs? Don’t be impressed by name brands. They count on that. Your best friend is Google images. Use it to look inside and compare.

If you look at the finest cost-no-object tube preamps, ones costing $20,000, $30,000, even $40,000, you will see several things in common: The best tube preamps will be dual mono, meaning discreet circuits for the left and right channel with no shared parts. They will be tube rectified; meaning pure tube throughout. They will have point to point wiring; no printed circuit boards. They will use an analogue volume control, not a chip. They will have multiple tubes in each channel instead of resorting to negative feedback or cheaper hybrid designs. And finally, they will weigh something instead of being an empty box.

You get all this and more with the PrimaLuna DiaLogue Premium Preamplifier at just $4499

Remember: Industry experts, reviewers, and speaker manufacturers use the PrimaLuna DiaLogue Premium Preamplifier as their personal reference; writing reviews, personal listening, even making the records you buy. The price is not an issue to them. It’s their work, and they want the best.

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.

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.

MUNDORF MCAP EVO SILVERGOLD CAPACITORS

Made in Germany, 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.

DUAL TOROIDAL 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. They are massive, resulting in a preamp weighing a substantial 53 pounds.

TUBE RECTIFIED

In the world of preamps, experts agree that tube rectification is the gold standard. It’s quieter than solid state rectification, dropping the noise floor. And it offers the most natural, textured, and vibrant presentation because the circuit is now pure tube. But because it is expensive to implement, you’ll only find it in the top of the line models typically costing  $10,000 or more. Finding a preamp using one rectifier tube is sweet. PrimaLuna goes even further using two 5AR4 rectifier tubes in a dual-mono design to present your music with a three-dimensionality that will give you goosebumps.

JAPANESE ALPS BLUE VELVET POTENTIOMETER

The best tube preamps use analogue volume controls. Not volume control chips. Look inside the most well-known brand of tube preamps and you will see a chip called a DS1666-10 Digital Resistor IC. At Primaluna, we understand the temptation to use this chip as they cost $8 each (half that in quantity!). The preamp will sound fine and be quiet, but true to “chips” it will add an electronic “sheen” to the sound. PrimaLuna prefers analogue. And we use the Gold Standard in motorized potentiometers:  The iconic Alps Blue Velvet. Why? Because they track perfectly, stay quiet, and don’t sound like chips!

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.

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 DiaLogue Premium even uses Swiss-made silver-plated OFC wire. The entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.

 

NO INTERNAL DAC / NO INTERNAL PHONOSTAGE

Never buy a preamplifier with an internal DAC. Why? Because digital changes, and history shows that preamplifiers with “old” digital become unwanted and have almost no resale value.

Built in phonostages are “throw in” and are rarely good quality because manufacturers assume 90% of buyers won’t use them. The external phonostage market is very competitive. You can get something much better for as little as $400, and buy one that actually meets your cartridges needs and YOUR budget.

DUAL-MONO DESIGN

Expensive and exotic preamps always use a dual-mono design to achieve a level of imaging not possible otherwise. Most manufacturers don’t employ dual-mono because of expense. It requires two power transformers, double regulation circuits, and in fact….everything is double. In effect, dual-mono means building two discrete and separate preamps into one box. It is so expensive to build, it’s a rarity even at the highest price points. All PrimaLuna preamps are dual-mono for the ultimate in stereo imaging and a sense of space that goes on forever.

SMART GAIN DESIGN

A preamplifier is typically not required to add any gain to your system when you are using it. It is usually lowering gain from the source you are listening to. The number one complaint from audiophiles about preamp performance is noise. So why is it that so many manufacturers design preamps with 20 to 27dB of gain? And you wonder why there is “hiss”, and why tubes go noisy or microphonic? PrimaLuna preamps use SmartGain. With a gain specification of only 10dB, you will find your PrimaLuna preamp is as quiet as a church mouse. If tubes are less than perfect, you may never know it because they are not amplifying as “loud”. High efficiency speaker owner’s rejoice!

PERFECT MATCH

Another exclusive PrimaLuna feature is PerfectMatch, a circuit designed to present a perfect 100K ohm impedance to your source components. This is vitally important especially for tube source components, such as phonostages and DACs to sound their very best.

DIALOGUE FRONT-END CIRCUITRY

The DiaLogue Premium uses three 12AU7 tubes per channel. The result is even lower distortion and increased bandwidth over ProLogue. The change in dynamic range is stunning! Distortion levels in the first stage have dropped by a factor of five at low levels, and at least 20 at higher levels, above one volt. The four 12AU7’s on the outside are driver tubes. By using four instead of two, we can swing more voltage. The two tubes in the center are the input tubes, and that’s where you want to have fun later if you wish by experimenting with different tube brands.

A price too good to be true, usually is.
If you’ve ever searched for a product on a shopping engine (such as Priceme/Pricespy) you may have asked yourself, “Why are some stores charging so much less than other stores?”

Our customers often share these stories with us, so we thought we would share a few with you, in hopes that you don’t fall prey to any of these unscrupulous sales tactics.

  • Goods may be grey market/parallel imported. They may state that the product includes the manufacturer warranty, but not tell you that the warranty is valid only in Europe, Japan, or South America, and NOT in NZ.
  • You may be asked to buy an expensive extended warranty. In many cases if you do not purchase the warranty, your purchase will be denied. (The product is now out of stock, your card does not go through, etc.)
  • Included parts may be sold to you separately. Some resellers will open boxes and charge extra for parts that are normally included by the manufacturer.
  • Hidden charges which don’t show up until your credit card statement arrives, these charges only show up when your credit card statement is sent to you.
  • When something goes wrong, faulty, late delivery, doesn’t matter how many times you try to email, they don’t get back.
  • There are so many scamming online sellers today, “buyer beware” protect yourself!

Concerned About Fraud?

The internet has become a more popular source for online shopping, regrettably we have seen more and more instances of fraud affecting online shoppers. Companies trading under many  different names, loading warranties and charging for them as extras when often they are included from the manufacturer. Parallel imports or personal imports where the NZ supplier refuses to repair when things go wrong is often alarming to the unsuspecting purchaser. Inflated freight charges, customs and GST at the border are often forgotten as a buyer is tempted by a lower price. Constantly we hear all these stories, once bitten it’s all to late looking for that refund or replacement. The stories are outrageous at times, customers from Trademe and ebay with no place to turn, time consuming and very frustrating….

So how do you protect yourself from online fraud?

  • Buy from an authorized reseller. If you are at all suspicious, contact the manufacturer directly and ask if a company is authorized to sell their products.
  • Make sure you get a company invoice with GST clearly marked.
  • Make sure you buy from someone who has a phone number and an address on their website, not a P.O.Box number
  • Read customer feedback, you can usually tell if it’s genuine or not.

We hope that you will become our next happy customer. And we promise to offer you superior service before, during and after your purchase.
