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]

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]

GSPre PREAMPLIFIER The GSPre is the nerve center of a system – not only directing signals and providing attenuation, but also interpreting and deciphering complex signals to create a musical story with the drama and intrigue befitting your favorite songs. The job of a preamplifier is to do its work discretely, leaving the musical signal with as little signature as possible ...[more]

OBravo Audio HAMT-1 headphones combined one of the best tweeter technology, AMT tweeter and a great bass performance Dynamic driver, with a multiple countries patented structure design to create a brand new listen experience in over-ear headphone market.. ...[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]

The Hercules II Mono employs a revolutionary twist on the concept of a fully balanced amplifier. In all balanced amplifiers, mirror-imaged amplifier circuits are used, with one part amplifying the positive half of an audio signal, and the other part amplifying the negative half. Yet in other balanced amps, the two halves are not quite equal, because one uses N-type transistors and the other use...[more]
