Stereophile magazine recommends PrimaLuna ProLogue Premium Integrated amplifier


PrimaLuna ProLogue Premium Integrated amplifierPrimaLuna ProLogue Premium
Designed in Holland and made in China, the solidly built ProLogue Premium is rated to deliver 35Wpc with EL34 tubes or 40Wpc with KT88s. It has a heavy-gauge, ventilated case with a lustrous five-coat finish, features point-to-point wiring, and offers five pairs of RCA input jacks, a Home Theater bypass, and connections for speaker loads of 4 and 8 ohms. Though it lacked the three-dimensional imaging, detailed highs, and extended bass of more expensive amplifiers, the ProLogue Premium produced a natural, inviting midrange and performed well with a wide variety of speakers. “The PrimaLuna ProLogue Premium offers outstanding sound quality at a very reasonable price,” said RD. JA noted respectable measured performance for a classic tube design.

Stereophile magazine recommends Micromega AS-400


Micromega AS-400Micromega AS-400
Housed in a metal enclosure with an attractive powder-coat finish, the AS-400 combines a class-D integrated amplifier with a high-quality moving-magnet phono stage, a D/A converter tailored specifically to computer music files, and a convenient iTunes-ready WiFi receiver. Though it lacked color and spatial depth, the AS-400 was dynamic, dramatic, and almost relentlessly exciting, for a consistently compelling overall sound, said AD. Music streamed from Art’s iMac was slightly clearer and had a more natural sense of flow than that streamed from his iPod, but both sources provided enjoyable listening. “The Micromega AS-400 strikes me as a virtually perfect choice for the audio perfectionist who shares space with other listeners—and multiple iPods and/or iMacs,” he concluded.

Stereophile magazine recommends PrimaLuna DiaLogue Premium Integrated amplifier


PrimaLuna DiaLogue Premium Integrated amplifierPrimaLuna DiaLogue Premium Integrated amplifier
PrimaLuna’s top-of-the-line integrated amplifier is rated to deliver 32Wpc with its stock EL34 output tubes or 43Wpc with optional KT120s. It uses PrimaLuna’s Adaptive AutoBias feature for easy swapping of output tubes, and has a bad-tube indicator, power-transformer protection, and output-transformer protection circuitry. The DiaLogue Premium was extremely quiet and sounded bigger than its power rating suggested, with a rich midrange and an excellent sense of timing, said ST. “The DiaLogue Premium will be a dream come true for anyone who has a closetful of output tubes,” he concluded

Stereophile magazine recommends the Audio Research VSi60


Audio Research VSi60Audio Research VSi60
In the 50Wpc VSi60, a passive line stage is combined with a JFET input stage driving one 6H30 driver tube per channel. Each channel’s output stage has a matched pair of Svetlana 6550C push-pull tubes with a combination of pentode operation and ARC’s “partially cathode-coupled topology.” Convenient to use, the VSi60 provides output taps at 4 and 8 ohms, as well as four pairs of voltmeter test points. Though it lacked the ultimate control of more powerful amplifiers, the VSi60 combined a glorious midrange with clean, detailed high frequencies and outstanding low-level dynamic articulation. “In the VSi60, Audio Research has produced an integrated amplifier of staggering quality, versatility, and value,” said BJR. Add $300 for tube cage.

Stereophile magazine recommends the PrimaLuna DiaLogue Premium


PrimaLuna DiaLogue Premium Integrated amplifierPrimaLuna DiaLogue Premium

Rated to deliver 25Wpc in Triode mode or 42Wpc in Ultralinear, the extremely versatile DiaLogue Premium is a push-pull design that uses six 12AU7 and four EL34, KT88, or KT120 power tubes. Like other PrimaLuna models, it offers: an LED-based Bad Tube Indicator system for the output tubes; a Power Transformer Protection circuit; an Output Transformer Protection circuit; an AC Offset Killer circuit intended to eliminate hum; and an Adaptive Autobias circuit. With every recording AD played, the DiaLogue Premium exhibited an open, clear, and dramatic overall sound, with good tonal balance, realistically weighty bass, and remarkable spatial depth. “A very strongly recommended amplifier and a hell of a good value,” AD concluded. Due to the amp’s high output impedance and its rising distortion when the load impedance drops below the nominal value of the output-transformer tap, careful matching with the user’s loudspeakers is mandatory, cautioned JA.

Stereophile magazine recommends Dan D’Agostino Momentum monoblock


Dan DAgostino Momentum monoblockDan D’Agostino Momentum monoblock
Dan D’Agostino’s statement product, the 300W (450W at actual clipping into 8 ohms) Momentum has a compact chassis (12.5″ W by 5″ H by 21″ D) machined from a single aluminum billet. A large, round power meter dominates the front panel, while thick copper side panels act as heatsinks. The low-feedback, fully complementary, balanced design uses 1% metal-film resistors and two dozen 69MHz output transistors in a direct-coupled, discrete, bipolar output circuit with a claimed frequency response of 20Hz–20kHz, ±0.1dB. The Momentums produced a seamless overall sound, with slightly reserved highs, a tube-like midrange, and an authoritative bottom end, said MF. “With the darTZeel NHB-458, it’s one of the two most satisfying power amplifiers I’ve ever heard,” he concluded. “This is an amplifier that is as well engineered as it is beautiful to behold,” said JA. Add $5000 for black finish. (Vol.36 No.2 WWW)

Stereophile magazine recommends the Conrad-Johnson Classic 60 SE


Conrad-Johnson Classic 60 SEConrad-Johnson Classic 60 SE
The Classic 60SE uses four Tung-Sol KT120 tubes to deliver 60Wpc into 4 or 8 ohms. Upgrades over the standard Classic 60 include Teflon capacitors in the power supply and main reservoir, Vishay resistors at key points, and Cardas binding posts. With its handsome tube cage in place, the Classic 60SE measures 17.4″ W by 6.6″ H by 13.4″ D and weighs 41 lbs. It combined exceptional dimensionality, pinpoint imaging, and excellent low-level resolution for an overall sound that was “the antithesis of mechanical or contrived,” said ST. (Vol.35 No.4)
