The Papa Dock is a dedicated power amplifier for the Krell KID iPod dock. Based on classic Krell amplifier technology, the Papa Dock mates directly with the KID and supplies an impressive 150 watts of power. Coupled together, the Krell KID/Papa Dock pair work as one to deliver audiophile performance to any iPod listener. Externally simplistic but internall...[more]

The PH3 is a phono preamplification stage intended for use with an active line-level stereo preamplifier. Fully single-ended from input to output, the PH3 uses a combination of J-FET input stage technology (for low inherent circuit noise) and class A operation vacuum-tube gain via three 6922 twin triodes. Total gain of the PH3 is 54 dB (non-adjustable). Used with typical line preamplifiers...[more]

The choices of the load are 47K, 1000, 500, 200 or 100 ohms. All functions are duplicated on the remote control. The rear panel includes a pair of single-ended inputs, a ground, and a 15A IEC connector. The PH6 is a hybrid (like PH5), with high-gain JFET input constant current and stadiuo stabilization without any counter-reaction. The PH6 uses four 6H30 twin triodes. Instead of replacin...[more]

The PH7 has 57.5 dB of overall gain, and features one pair of single-ended inputs and outputs. Full remote control is provided for all functions, coupled to an easily readable front-panel vacuum-fluorescent display. The display shows all selected functions including loading (47K, 1K, 500, 200, 100 ohms), as well as accumulated hours of operation. Display intensity can be adjusted to one of eight l...[more]

Operationally, the PH8 maintains the flexibility and ease of operation of its predecessor, with loading (47K, 1K, 500, 200, 100 ohms), Stereo/Mono, Muting andPower buttons under a vacuum fluorescent display that has eight selectable brightness levels. The display can be turned off, with nine small pixels remaining dimly lit to remind one that the supplied remote control. There is one set of single...[more]

The crossover functionality offers the ability to use a subwoofer/satellite speaker arrangement and still maintain the highest quality sonic performance. Previous to the Phantom preamplifier, this system configuration would require signals to pass through a subwoofer's lower quality crossover circuitry. The Phantom preamplifier is the centerpiece of a world class audio system where space is at ...[more]

Sharing the same audio circuitry as its bigger brother, the Phantom II preamplifier is a dual monaural circuit design with the left and right channels afforded their own power supply regulation and individual full chassis sized boards. All signal gain is realized in surface mount topology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other desig...[more]

Circuitry Highlights The Phantom preamplifier is a dual monaural design with the left and right channels afforded their own power supply regulation and individual circuit boards. All signal gain is executed with surface mount technology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. Featuring 700 kHz bandwidth in a zero feed...[more]

Incorporating the best electronic elements of the original ProLogue Three, plus selected ground-breaking features from the more advanced DiaLogue Series, the next generation ProLogue Premium Preamplifier is an engineering marvel — setting a new benchmark in high-performance audio with the following features: *Home theater pass-thru. Straight from the critically-acclaimed DiaLogue Seri...[more]
