The S-300i is the first Krell integrated amplifier to feature iPod connectivity and extends the award winning tradition of audiophile grade integrated amplifiers.

A low profile chassis fronted by an elegantly finished silver Aluminum front panel hints at the potent circuitry hidden within its walls. Small in stature but big in performance, the S-300i integrated amplifier develops 150 W into 8 Ohms and 300 W into 4 Ohms. Employing a massive 750 VA toroidal transformer and 38,000 microfarads of capacitance guarantees huge power capability for maximum dynamic impact. Both balanced and single-ended inputs are provided, and the Theater Throughput(tm) mode, developed by Krell, simplifies integration into home theater systems. Robust WBT binding posts provide superior loudspeaker cable termination. New for the S-300i is direct connection for all generations of Apple iPods /iPhones with complete control of the iPod functionality via the included remote control. Unique for the category, the S-300i taps audio from the fully differential output included in the internal DACs of iPods/iPhones and maintains this balanced signal throughout the circuitry.

The S-300i features the latest Krell Class A, direct coupled design, and fully balanced preamplifier circuitry for the lowest noise reproduction possible. Krell Current Mode provides unequaled bandwidth for the most revealing playback of today’s high resolution music sources. Direct coupled circuitry eliminates impact-robbing capacitors from the signal path and an elegant, custom-machined level control adjusts volume.

The included solid aluminum remote control replicates all front panel options as well as providing control for a connected iPod/iPhone. RS-232 is also included for inclusion in advanced control systems.

Here is what the critics are saying!

Sound and Vision

“A great-sounding, reasonably priced analog two-channel integrated amp from a high-end brand that many people thought they would never be able to afford âeuro” and it’s got an iPod interface, too”

AV Guide

“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.”
