A Real Powerhouse with Delicacy and Finesse

The Krell S-300i Integrated Amp Would Be a Steal at Twice the Price!

Krell electronics strike a chord with audiophiles and music lovers the world over! Delivering immense satisfaction in those who own them, and intense jealousy in those who don’t. Based on technology from Krell’s flagship Evolution Series of separates, comes a true high-power integrated amp: The S300i. This fifty-pound amp packs a ton of muscle, delivering 150 watts/channel into 8 Ohms and 300 into 4 Ohms. The S300i also employs a Class-A, fully-balanced Krell Current Mode Preamplifier section which provides unequaled bandwidth. The S300i even comes complete with real WBT binding posts to ensure a strong secure cable connection. As always, Music Direct offers our 100% Satisfaction Guarantee on the Krell S300i, so get one in your system and audition it for 30 days. If you're not completely blown away by the performance... we'll take it back!

“Your first realization that this is no ordinary integrated is its weight; it tips the scales at almost 45 pounds. Such wallop! Such extension! Such sheer mass… and the S300i flexes its muscles in another area: retrieval of detail. The sound space is so huge, wall-to-wall and stretching into the sonic vanishing point behind the speakers. I simply didn’t expect this from a unit so compact and so relatively affordable. The S-300i behaves like a $10,000 pre-power combo. This is an inexplicable, insane give-away. I love it!”
-Ken Kessler, Hi-Fi News, February 2009

No ordinary amp here, the Krell S-300i sets its sights on much more expensive products and supersedes all expectations! Detail retrieval, frequency extension and liquidity are top of the class and just like all Krell amps, the S-300i handles any speaker load. The S300i sets a new standard not only for integrated amps but for all components anywhere near its price range. We’re calling this $2500 integrated amp a bargain, words we don’t use lightly. Try this amp in your home, in your system; we know you’ll be blown away!

The S-300i integrated amplifier combines a fully balanced, Class A preamplifier circuit with a stereo amplifier rated at 150 watts per channel into 8 ohms and 300 watts per channel into 4 ohms. Its circuit design borrows the Current Mode technology used in Krell’s top-of-the-line Evolution amps and preamps. This technology delivers unequaled signal bandwidth, ensuring clear, powerful response from the deepest bass notes to the very top of the frequency bandwidth. A massive 750 VA toroidal transformer and 38,000 microfarads of storage capacitance make the S-300i’s amplifier section one of the most robust ever incorporated into an integrated amplifier.

“Few components strike fear in an audiophile’s lumbar region like the heavyweight electronics from Krell. This integrated amplifier is little more than four inches high, but this powerhouse is pure Krell through and through. At 43 pounds, it outputs 150Wpc and doubles that rating into 4 ohms thus likely making the S-300i the most powerful amp in this price range. I had to continually remind myself that the S-300i is only a $2500 amp; yet I was comparing it to amps twice the price and more! What blew me away was the balance Krell has struck between the sonic expectations of traditional audiophiles and a new generation of hobbyists whose priorities also include modern functionality and features."
– Neil Gader, The Absolute Sound, June/July 2009

The S-300i delivers state-of-the-art conveniences audiophiles might not expect. First among these is its included iPod/iPhone interface. Like Krell’s award winning KID iPod/iPhone dock, the S-300i’s iPod/iPhone interface taps audio from the fully differential (balanced) output included in iPods and iPhones—a capability no other manufacturer has used. A cable for iPod/iPhone connection is included. The solid aluminum remote controls the S-300i, the playback functions of a connected iPod or iPhone, and Krell CD, SACD, and DVD players.

The bottom line: Krell quality and performance are finally within reach of many more music lovers, and at this level of performance... this Krell can't be beat!
