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.

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)

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)

Stereophile magazine recommends Audio Research Reference 75

Geplaatst op 17/04/2014 door hermanvandendungen

Audio Research Reference 75Audio Research Reference 75
A half-power version of ARC’s Reference 150, the 75Wpc Reference 75 uses four KT120 and two 6H30 tubes. Two front-panel VU meters double as adjustment meters for biasing each of the four KT120s. A relatively simple, straightforward circuit design enables short signal paths; high-quality output transformers offer 4 and 8 ohm taps, with a common ground. BJR noted lightning-fast transient articulation, superb detail resolution, and exceptional bass slam and authority. He bought the review sample. JA noted good measured performance, but advised against using the amp with speakers whose impedance drops significantly below the nominal value of the output-transformer tap.
