AC OFFSET KILLER - A PRIMALUNA EXCLUSIVE

AC Offset Killer 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.

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.

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 31 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 $4 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 entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.

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.

SMARTGAIN 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 10.8dB, 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!

PERFECTMATCH

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.

Satyajit Ray's Great Trilogy Masterpiece Gets the Criterion Treatment In Blu Ray!
Years before trilogies were in vogue, way before "The Godfather" there was "The Apu Trilogy". The original negatives were lost in a fire and yet Criterion has managed to work miracles with this masterful restoration of this beautiful classic tale of the life of a Bengalese child to adulthood over 3 films. The story is compelling and absorbing and directed as only a master like Satyajit Ray can. Any attempt to further describe this movie would just not do justice to it; it has to be experienced and rewards repeated viewing. This release also includes a 48-page booklet of essays on the film in addition to the 3 blu ray discs of the films. Great sound and picture quality is evident as well considering the film's age and source master. This worthy addition to any art-film buff's video library comes highly recommended!

What is the point? (SPOILER)
My heading echoes the adult Apu who, in the last movie in the trilogy says, "What is the use?" and allows the pages of his autobiographical novel to blow away in a wind. In the first two movies we enter the very real life of a rural Indian family whose members are all lovingly created by director and actors. But their story is rather sad. First Apu's young sister dies of illness, a fate shared much later by their father. Then the life of the mother dwindles away and Apu is left alone. The restoration of the nearly-destroyed films is a technological marvel, but I wondered if this tale would attain to anything of lasting value by the end. With the third and last movie in this series, I can reach a somewhat different conclusion. There is death and suffering in this last part too as Apu's wife dies early on but the entire narrative reaches a sudden and surprising resolution when Apu unites with his long-abandoned little boy who is himself a mirror of Apu growing up. There is something of a vacuous Asian experience in this cinematic telling but it doesn't really come to nothing as the stereotype might suggest. I recall that experience in David Lean's rendering of E.M.Forster's A Passage to India, a wonderful movie too but, like the novel, lending itself to earlier Western ideas about the East. An element of life, freedom, joy bursts upon us at the end of Ray's movie and transforms everything we have seen before. Yes, life is risky, unpredictable, filled with suffering, but it can still lead to something wonderful.

Masterpieces of Indian cinema
A memorable trilogy by Indian master filmmaker, Satyajit Ray. My personal favourite of the three is the first one, Pather Panchali (Song of the Little Road). It is a moving and extraordinary portrait of rural poverty in India, focused on the trials and tribulations of a struggling family. This trilogy is a must for the collections all lovers of world cinema.

Custom Mailer
Excellent item as you probably know . I'm THRILLED about the shipping all around & fast delivery to porch but I would like to compliment whomever is responsible for custom cardboard mailer it came in. I worried reading some of the major complaints from recent years about packaging issues and damages suffered to box & DVD's . It would appear that the manufacturers corrected this issue. I'm very happy with our distribution outlet in El Paso , Texas . I'm west 90 miles from in New Mexico and I think they terrific and professional. Not one order came damaged , late or poorly packaged so Thank You all responsible parties. Oh yeah , the ''Essential Fellini'' anthology ( minus a few films not added and missing correct documentary Ive seen about the director ) is your final replacement !

The best Fellini collection on the US market
The collection is a bit pricey, but in this case you get what you pay for. These movies have all been restored beautifully, and the box is a delight. The packaging is a fairly sturdy cardboard box. It is quite large, so you may have trouble fitting it onto a bookshelf. Mine protrudes about an inch past the end of my shelf. Inside the box is a large folio for the discs and two novel-sized books. One is a guide to each of the films, and the other is full of essays about Fellini and his work. The movies all look great. The blu-ray upgrades look great compared to my old vhs or dvd copies of some of his works. There was a new restoration of all of these films right before the set came out, and it shows. The black and white contrast looks crisp and the color films really pop. As for the quality of the films, you know that some of these are considered top films of all time. The lesser films are still good to great. I think that all of these films are worth watching over and over, and all of them have great special features. All in all, this set is very much worth it, especially during the July sale. I bought it half price, and I feel I got an incredible bargain. All in all, this is probably the best Criterion box set. Don't hesitate, buy it.
