The Full Power Balanced X Series Stereo Amplifiers offer the greatest performance possible from a stereo amplifier. All X Series amplifiers share the same circuit topology, from the 300 Watt Full Power Balanced 300cx and the mid-level FPB 400cx at 400 Watts, to the awesome 700 Watt FPB 700cx, the most powerful stereo amplifier ever offered by Krell. While the amplifiers have much in common, there ...[more]

With the introduction of the Master Reference Amplifier in 1999, Dan D'Agostino established a level of amplifier performance without equal. The new X Series of Full Power Balanced monaural amplifiers are the direct descendants of this design. Sharing the same circuit topology as their stereo counterparts, the monaural amplifiers raise sound reproduction to a new level by dedicating an amplifier fo...[more]

Highlights Fully balanced circuitry from input to output insures signal integrity, rejects noise, and improves signal-to-noise ratios to deliver a "night and day" sonic difference when compared to typical single-ended circuitry. Computer regulated power supply provides consistent sound quality at wide dynamic range regardless of fluctuating line voltages. Current mode operation ensures wide b...[more]

GS150 POWER AMPLIFIER An amplifier is the workhorse of any system – it is responsible for receiving small signals from a preamplifier or source component, and developing them into larger currents to control a loudspeaker. To that end, the GS150 has been designed to seamlessly integrate into any system and steadfastly perform its task. Challenging source material and difficult sp...[more]

A preamplifier, amplifier, phono stage, and digital to analog converter all in one chassis, the GSi75 combines with your favorite speaker to deliver a singular and simple solution to control your listening system. Unlike other integrated designs that make performance - sacrificing compromises to fulfill a price point or form factor, the GSi75 harnesses the power and technologies developed by...[more]

We call it "Hybrid Drive" because that’s how it works.  As in the REF110, a JFET input (for low noise) feeds a 6922 dual triode gain stage, which in turn feeds a 6H30 dual triode cathode follower which drives the outputs through our proprietary coupling capacitors (first used in our REF3 preamp).  This vacuum-tube input/driver arrangement sets the stage for superbly musical perform...[more]

JA 100 This is the first of the new JADIS amplifier range with new schematics and new output transformer. ...[more]

JA 200 An aesthetic look of parallels and diagonals. The JA 200 amplifier reveals a perfection of lines and its two blocks per channel respond to an unusual symmetry of forms and colours. When the eye follows the opposite diagonal, it is caught first of all by the black shape of the output transformer, then by that of the capacitors at the rear end of the other block. Black on black, chrome on ...[more]
