Krell S-550i integrated amplifier

Geplaatst op 28/04/2014 door hermanvandendungen

With a power output of 275W per channel into 8ohms, rising to 550W into an 4ohm load, the S-550i comes complete with both single-ended and balanced inputs, a dedicated iPod dock and Krell’s Theater Throughput mode, enabling it to be integrated into surround sound systems.

The preamp section is based on Krell’s Phantom preamplifier design, with no capacitors in the signal path, discrete balanced circuitry, current mirrors for high linearity and no negative feedback.

The volume control uses a balanced resistor ladder for optimum signal quality and linearity, Krell claiming that ‘bandwidth and transient response of the preamp circuitry are virtually unaffected by the volume setting’.

Despite its relatively compact dimensions, the amplifier packs a 1750W transformer and generous power supply capacitor storage, and the power section again uses all-discrete circuity, and like all of the company’s power amps is designed as an ideal voltage source, doubling output as speaker impedance halves.

The Krell S-550i has one balanced input, three single-ended inputs on RAC phonos, and a dedicated 30-pin input for the iPod dock supplied. It also has an RS-232 control input, a connection for an external infrared sensor, and 12V trigger inputs and outputs.

Basic iPod control functions are available from the remote control supplied, which can also control a Krell CD player.

Stereophile magazine recommends Sonus Faber Venere 1.5

Geplaatst op 27/04/2014 door hermanvandendungen

Sonus Faber Venere 1.5 Sonus Faber Venere 1.5 The Venere 1.5 is a two-way, front-vented, biwirable bookshelf speaker measuring 15.4″ H by 8″ W by 11.7″ D and weighing 13.2 lbs. It uses a 1.25″ silk-dome tweeter with a conical waveguide and a 6″ Curv-cone mid/woofer. Like the larger Venere 2.5, the 1.5 has a beautifully finished, internally braced cabinet whose sidewalls curve around to meet a very narrow rear panel just wide enough to accommodate a staggered array of four multiway terminals. Though it lacked high-frequency sparkle and exhibited a slightly elevated upper bass, the Venere 1.5 produced a natural, dynamic, and involving overall sound, with a detailed midrange and delicate highs, said BJR. Price is for black or white high-gloss lacquer finish. Borderline Class B overall. Durob Audio was the exclusive distributor for Audio Research in the Benelux.

Stereophile magazine recommends Sonus Faber Venere 2.5

Beautifully finished in black or white lacquer, the Venere 2.5 is a compact (43.2″ H by 13.3″ W by 17″ D), 2.5-way, reflex-loaded design with a 1.1″ fabric-dome tweeter, a 7″ Curv-cone mid/woofer, and a 7″ Curv-cone woofer. The cabinet’s sidewalls curve around to meet a very narrow rear panel just wide enough to accommodate a staggered array of four multiway terminals; the cabinet sits on a thick glass base plate that accepts four substantial spikes, the front pair nearly an inch longer than the rear, so that the entire cabinet tilts back to align the tweeter with the deeper woofer diaphragms. The sound was spacious, relaxed, and well balanced overall, with detailed mids and highs and a rich lower midrange, said KR. “The Venere 2.5 is not only provocatively sexy in appearance; it delivers,” he concluded. The Venere 2.5 exhibited an exaggerated midbass on the test bench, but offered “respectable measured performance” overall, said JA.

Stereophile magazine recommends Sonus Faber Guarneri Evolution

Sonus Faber Guarneri Evolution

The beautiful Guarneri Evolution is a two-way, port-loaded, stand-mounted loudspeaker with a 1″ fabric-dome tweeter and 7″ pulp-cone woofer. It measures 16.5″ H by 9.25″ W by 16.2″ D, weighs 40 lbs, and uses an intricate mass-damping system trickled down from SF’s flagship, The Sonus Faber. Though it sounded somewhat congested when used with AD’s 25W Shindo Corton-Charlemagne monoblocks, the Guarneri Evolution produced richly textured, natural tone and delivered detail without edge or glare. “For the listener who delights in the rich, saturated, velvety tones of real instruments and voices, I can think of no more appropriate loudspeaker,” said AD. JA found superb measured performance.
