Vacuum tube rectified power supply adapted from the award-winning ProLogue preamps incorporates eleven separate power supply regulation circuits. Tube rectification is synonymous with organic sound, especially with CD players being known as sounding like "a computer".
USB digital input allows using your computer for storage and playback of your music with all the benefits of features like playlists and easier access to your whole music library. Rather than just add in an USB input as an afterthought, PrimaLuna engineers searched endlessly looking for the best-sounding USB interface we could find.
We found the hiFace, made by M2Tech in Italy. Home Why PrimaLuna? Tube Rolling. Revolutions are born in bold ideas SuperTubeClock An ultra-low jitter clocking device that replaces the solid-state oscillator with a vacuum tube. Premium Parts Premium parts including polypropylene coupling caps, triple pi power supply filters, custom designed isolation transformers which separate the analog and digital devices, resulting in decreased signal degradation and improved sonics from top to bottom.

Ken Kessler and Paul Miller Nov 1, Emblematic of the evolution of the Chinese-made valve amp is PrimaLuna's ProLogue Premium - in case you hanker after a value-for-money integrated with no rough edges This year, my son turned 21 and graduated from university.

T he PrimaLuna line of audio equipment was founded by Herman van den Dungen, a distributor from the Netherlands, where its origins date back to the year Paired together with Marcel Croese of Goldmund fame and Dominique Chenet of Jadis fame Herman Dungen brings high end musical reproduction to those of us on a much smaller scale budget than that found with the elite group of cost no object audiophiles.
Great care is taken to assure PrimaLuna products offer an excellent value, deliver superior sound, provide top aftermarket service and are sold at minimal costs to the consumer. That is quite a tall order if you ask me.
The philosophy of Mr. Dungen is to put together a team of top people from their respective fields while using lower cost manufacturing facilities located in China. Under the watchful eye of this European based company, with its Western design and marketing strategies, PrimaLuna products have gained worldwide recognition as can be attested to by reading the many positive reviews from various trade publications around the globe.
In Italian PrimaLuna means "First Moon", with reference to family nicknames starting back with his Grandfather and now adopted as a logo for the company. Technical Information The following was taken from PrimaLuna's website and then condensed a bit. This unit incorporates the best electronic elements of the original ProLogue Six and Seven, plus selected features from the more advanced DiaLogue Series.
A new Adaptive AutoBias circuitry, enabled by simply flipping a switch, allows user to re-calibrate the monoblocks for optimum operation of EL34s or KT88s. Every ProLogue Premium Series amplifier can be ordered with either set of power tubes installed. This circuit continuously monitors and adjusts each tube to run in its sweet spot.
This circuit works hand-in-hand with the new Adaptive Auto-Bias circuit. A PTP-circuit protects the power transformer in case of overheating while the OTP-circuit Output Transformer Protection circuit protects the output transformers in the event of a massive tube failure or user error.
Internal parts include Solen capacitors and fast-recovery diodes. There are new output and power transformers that were designed after those in the more advanced DiaLogue Series. These heavy-duty, high-efficiency transformers offer better control over challenging speaker loads, as well as increased detail and musicality. Other features include point-to-point wiring, ceramic tube sockets, Nichicon capacitors, WBT-style core speaker terminals and gold-plated RCA jacks.
As you can see both the production and design concept of these amplifiers have been carefully thought out. The ProLogue Premiums take most of the guess work out of tube ownership with self-biasing circuitry, for both EL34 and KT88 power tubes, as well as the ability to pinpoint what particular individual tube or tubes have gone bad.
This should certainly allow novices to feel comfortable enough to purchase these beautiful amplifiers and discover the great joy of having tubes in their audio chain. For experienced tube enthusiasts, with older tube equipment and some newer ones as well , the self-biasing circuitry should be a delight.
While it can be fun to bias tubes it certainly is more convenient not to have to deal with that. I got an immediate call from my wife, proclaiming their heft, after they were dropped off at my doorstep and she carried them inside by herself. These works of art weighted in at just over 46 pounds apiece, sans packing, and she most certainly wanted her effort to carry them into the living room noted.
Luckily for me she is quite fit otherwise they might have sat on the porch unattended till my return later that evening.
After unpacking each amplifier and lifting them onto the top shelf of the audio rack it was quite apparent these were some serious pieces of iron.
If you like to equate pounds with cost you will be quite pleased with these mono block amplifiers from PrimaLuna. Of course as we are all aware we are not just purchasing pieces of metal but rather chasing top quality sound reproduction. Each amplifier came with a factory supplied power cord, sturdy but nothing out of the ordinary, and a pair of white cotton gloves for handing both tubes and equipment. For this review after market power cords from Cardas were used as well as power conditioning from Audience.
It is my assumption that most of us who purchase audio gear at this level will probably be using specialty power cords and power conditioning within their system. While sound quality using the stock cords was good my preference was to go with those from Cardas in an effort to bring out the best from these tube beauties.
They came with attractive cages but my initial thinking was to remove them in order to enjoy the glow from all those tubes. Home Why PrimaLuna? Tube Rolling. Dare to Compare Compare PrimaLuna construction to any other brand, at any price. We want you to know our prices. PrimaLuna represents the best value in the industry. Compare us to anyone. 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.
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. 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 Premium is about goose bumps.
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. The resonance of an acoustic guitar or violin string that seems to trail on forever. The AC Offset Killer will amaze you. 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?
Every audiophile has albums that they used to play, but stopped because they are harsh, brittle, or bright. There is a solution. But triode amps have limitations! Ultra-linear has more extension on the top and bottom, not to mention greater power. 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. In PrimaLuna introduced the original DiaLogue series; the first amplifiers designed to be as close to being future proof as humanly possible.
Back then nobody imagined a tube like the KT, let alone the KT, which combines the sweetness of a B with bass and control never seen before. Now other companies are scrambling to make a product built to handle the demands of this incredible tube. A small LED in front of each power tube lights up if the tube goes bad. The circuit then puts the amp into protection mode. With other brands, this may be when you have to break out the soldering iron to replace a plate resistor, and replace two or four tubes because your amp requires matched sets.
