IMPORTANT NOTES

INSTRUCTION FOR HANDLING OPTICAL SYSTEM BLOCK PICK-UP
Electrostatic breakdown of the laser diode in the optical system block may occur due to a potential difference caused by electrostatic charge accumulated on clothing, human body, etc. A ground must be provided as follows to prevent any electrostatic charge during unpacking or repair work. 1. Ground for Human Body Be sure to wear a ground band (1M ohm) that is properly to remove any static electricity that may be charged on the body. 2. Ground for Work Bench Be sure to place a conductive sheet (1M ohm) or copper plate with proper grounding on the work bench or other surface on which the pick-up is to be placed. 3. Because the static electricity charge on the clothing does not discharge through the body grounding band, do not let clothing to get in contact with the pick-up unit. INCORRECT CORRECT

1.Grounding band 1M ohm

1M ohm 2.Conductive Sheet or Copper Plate
NOTE: Laser diodes are so susceptible to damage from static electricity that even if a static discharge does not ruin the diode, it can shorten its life or cause it to work improperly.
PRECAUTIONS FOR CHECKING BEAM EMISSION
The laser beam of this unit is focused on the reflecting surface of the objective lens in the optical system block. Therefore, keep your eyes at least 12 inches (30 cm) away from the objective lens when the laser diode is ON. (Operation Check Method for Laser Diode and Focus Search Function.) When the POWER switch is turned ON after the chucking plate is removed, observe the objective lens and confirm that the following operations are performed properly. (The optical system should be at the lead-in area position when it is checked at this time.) (1) The laser should be at the innermost position after the chucking plate is removed. (2) The diffused light of the laser beam can be seen when the POWER switch is turned ON. (3) Vertical (up and down) movement of the objective lens (2 or 3 times) will take place.
PRECAUTIONS WHEN CHANGING LASER PICK-UP
When removing the pick-up assembly, short circuit the PCB tracks on the optical block as show in the drawing in order to protect the pick-up before removal. NOTE: Replacement pick-up assemblies are supplied with the PCB pattern already protected. DO NOT REMOVE THE SHORT CIRCUITS UNTIL YOU HAVE FINISHED FITTING THE PICKUP.
Protective soldering place for laser diode
Caution: Laser diodes are extremely susceptible to damage from static electricity. Even if a static discharge does not ruin the diode, it can shorten its life or cause it to work improperly. When replacing the pick-up, use a conductive mat, a grounded soldering iron, and so on, to protect the laser diode from static damage.

ProLogue Two integrated

as reviewed by Ed Kobesky
The most enjoyable system I've ever owned was also the simplest and least expensive. It consisted of an Onkyo CD player fed directly into a pair of Antique Sound Labs Wave DT SET amps. Those little 8-watt beauties powered my Polk

RT25i monitors with surprising authority, and though the system was far from state of the art, it communicated the electricity of live music better than any I've owned since. Unfortunately, as I quickly discovered, tube gear can be finicky, especially on the budget end of the spectrum. The PrimaLuna ProLogue Two is the complete opposite. It could change everything for audiophiles who demand musicality and low maintenance. It's that important a product. Nearly every niggling problem associated with tubes has been effectively addressed, except for tube replacement, and even that has been rendered nearly hassle-free. Better still, the ProLogue Two made the hair on the back of my neck stand at attention every time I sat down to listen. For most audiophiles, the scariest aspect of tube ownership is biasing. Tubes decay over time, and tube amp designers provide a bias adjustment to optimize current flow for the least distortion. Some amps have a built-in meter for this. With others, you need a DC voltmeter, and maybe a pair of rubber boots. You could rely on your dealer to bias your amp, but the current at his or her shop might be different than it is in your home. The ProLogue Two eliminates this concern by way of its proprietary Adaptive AutoBias circuitry. According to PrimaLuna's U.S. importer, Kevin Deal of Upscale Audio, this means no adjustments, ever. You don't have to use matched pairs of tubes, or even the same type. If a KT88 blows out, you can temporarily replace it with an EL34 if that's all you have on hand. As with all tube amps, you'll need to replace the tubes every few years. Exactly how often depends on your listening habits. Some people get lucky, others don't. The good news is that if you can change a headlight on your car, you can retube a ProLogue Two. The tubes should cost between $100 and $200not exactly trivial, given the fact that you can buy a very good integrated amp for that much. Then again, it won't be as unique as the ProLogue Two. The only other special consideration regards cooling. Like all tube amps, the ProLogue Two needs open space on all sides, more space than a solid-state amp. If you can't give it at least four to six inches of space above and plenty around the sides, you'll want to put it on the top shelf of your rack or on a separate amp stand to avoid heat-related damage. Everything else you might worry about is handled internally, as the ProLogue Two hass a soft-start circuit to gradually bring the tubes on line, and an easy-to-replace fuse for protecting the output stage. Obviously it's practical, but the ProLogue Two is also plenty sexy. Available with the buyer's choice of silver or black faceplates, it sports a high-gloss lacquer finish in "black sapphire" (actually a blue-black) and a build quality that's nothing short of stunning for the price. A pair of white gloves is provided so you don't smudge the finisha classy touch. Kevin Deal triple-boxes every unit, and mine traveled from California to Pennsylvania without so much as a nick. There's no setup required aside from removing the foam tube protectors and plugging it in. Kevin Deal insists that reviewers take the bottom off and have a look for themselves, and I was not about to resist. I saw point-to-point wiringa nice touch, but not as uncommon as it used to be in budget gear. What is uncommon is the overall care of assembly and wire dressing. How they accomplish so much for so little money is no mysterythe ProLogue Two is assembled in China. For $1345, you even get a removable tube cage, which is generally an extra-cost option. It snaps on and off instantly. I left mine off because I couldn't bear to keep those gorgeous KT88 tubes all cooped up.

While the front of the ProLogue Two is the main attraction, the back looks pretty good as well, with a complement of beefy, gold-plated terminals you'd expect to find on a much more expensive product. If you're like me, you'll be giddy long before you tap the power switch.
Now comes the hard part, which is describing the sound of the ProLogue Two. Should I compare it to similarly-priced tube gear? I could, but much of its competition aims for a purposely soft, romantic sound that is initially appealing but unsatisfying in the long run. I could compare it to solid-state integrated amps I've owned in its price category, but they all seemed to shoot for maximum slam and detail. I decided to throw all comparisons aside and simply tell you what I heard.

The first thing I noticed was a unique sense of air and aliveness. Even before Keith Jarrett played his first note on side one, record one of the monolithic 10-LP box set, Sun Bear Sessions (ECM 1100 ), there was more atmosphere than I'd ever heard. It was downright eerie, and for some listeners, it could be revelatory. Get ready, analog fans: LP + KT88 = a synergy that's not to be believed. When the music started, the ProLogue Two surprisedno, shockedme by painting a smooth sonic picture that was also controlled and coherent. Many tube amps I've heard are slow in the midrange, dull on top, and loosey-goosey on the bottom. Not the ProLogue Two. It can't compete with solid-state amps in terms of tightness and fastness, but it never sacrifices detail to provide a warm, soothing presentation. It just sounds good, and not in a deliberately tube-like way. Music is presented in its entirety. At moderate to medium-high volumes, it does a remarkable job of sorting out instrumental lines, right down to the individual notes. I'd have no qualms about pairing it with sources and speakers that cost many times its absurdly low price. It also brought out the very best in budget gear. Whether fed the signal from my NAD C521i CD player or a $50 Sony CD Walkman, the results were musical. The ProLogue Two can be alternately forgiving and revealing. That, in a word, is magic. The ProLogue Two never put a foot wrong. It's the first amp I've heard in a long time that could bang out bass-laden hip hop tracks, as on The Streets' CD Original Pirate Material (Atlantic 93181), then turn on a dime and resolve the fragile shadings of a minimally-backed female vocalist like Holly Cole on her Tom Waits tribute record, Temptation (Metro Blue 8316532). It was human, expressive, and open sounding to a fault. The only way you'd outgrow this amp is if you upgraded to speakers the size of a Kia, and even then, the ProLogue Two could probably power them to a reasonable volume. There's another reason to consider the ProLogue Two. If you don't like the sound of your solid-state amp, you're pretty much stuck unless you're willing to risk going in with a soldering iron to replace resistors and capacitors. Even then, the benefits are usually subtle. Not so with tubes. You can have a blast trying different tubes until you get precisely the sound you want. It's a relatively cheap way to stave off an acute case of upgrade-itis. The PrimaLuna ProLogue Two may not be as energetic as a solid-state amp, nor will it exert the same level of control. That, however, is the key to its appeal. Music flows through it gracefully. What comes out is lush but not slushy, alive but not prickly, and involving as all get out. The PrimaLuna ProLogue Two garners my strongest recommendation. It's not merely a great tube amp, but a great amp, period.
