First, you will notice a more modern, monochromatic appearance, including a new front panel with a small aluminum power button: natural units include silver handles and top cover, while black units come with black panel, handles and top cover. A new analog meter replaces the vacuum-fluorescent digital display of its predecessor; this illuminated meter is capable of displaying power output, line...[more]

The REF75 is a great looking amplifier, slightly reminiscent of our older classic designs.  The front panel has two illuminated analog power/bias meters, one for each channel.  Under each meter is a knob to switch from power output to bias monitoring for each output tube.  Bias adjustment points are accessed from the front panel, too, offering real convenience.  The outer di...[more]

The appearance is more refined and attractive, but is clearly a statement piece from Audio Research. A new, optional 12V fan-cooled silver top cover is available at additional cost.   Using the now-standard KT120 output tubes (8 matched pairs, driven by another matched pair) in the classic Audio Research push-pull Class AB output stage, the input stage has been streamlined, using very low ...[more]

The S-150m is a slim line monaural power amplifier boasting our latest circuit topology and a substantial power output of 150 Watts into 8 Ohms and 300 Watts into 4 Ohms. The elegant exterior houses the technology developed in the Krell Evolution amplifiers including Krell Differential Current Mode circuitry and balanced operation. The S-150m is the ideal choice for high performance systems in ...[more]

The S-275 is a slim line stereo power amplifier boasting our latest advancements in circuit design featuring an impressive 275 Watts per channel into 8 Ohms and 550 Watts per channel into 4 Ohms in stereo mode. Setting the rear panel switch to mono operation, the S-275 boasts a massive output of 550 Watts into 8 Ohms and 1,100 Watts into 4 Ohms. Technologies developed for the Krell Evolution am...[more]

AUDIOPHILE GRADE INTEGRATED AMPLIFIER Employing a massive 750 VA toroidal transformer and 38,000 microfarads of capacitance, the S-300i sets the performance standard for integrated amplifiers. At 150 Watts per channel into 8 Ohms and 300 Watts per channel into 4 Ohms the S-300i is built to meet the demands of today's latest loudspeaker technology. A KRELL Class A, direct coupled design, ful...[more]

It was all a bit of shock back in the ‘90s when Krell suddenly introduced a neat little integrated amplifier in the form of the KAV-300i - such a contrast to their tradition of big, beefy power amps. But once past the scepticism we all realised, perhaps to our surprise, that this slim and unassuming device actually had a good measure of Krell’s unique signature: control, dynamics an...[more]

Like the larger HD220, the new SD135 ("SD" for "Silicon Drive") uses Thermal TrakŽ self-biasing output devices in a Class A-B design. And like the HD220, it accommodates either single-ended or balanced inputs. But unlike the larger hybrid, the SD135 features an all-solid-state input stage using multiple JFET devices in each channel, directly driving the output stage – no interstage coupling capa...[more]

The Vanguard’s amplifier incorporates a massive power supply with a 750 VA toroidal transformer and 80,000 microfarads of storage capacitance. The tremendous amount of energy on tap provides 200 watts per channel into 8 ohms and 400 watts into 4 ohms. Two quiet, thermostatically controlled fans permit the use of a surprisingly compact chassis. The preamplifier section of the Vanguard ...[more]

The Digital Vanguard incorporates a 200-watt-per channel amplifier and a Class A preamplifier, enclosed in a chassis that borrows its design and construction from the new Krell Foundation preamp/processor, Connect stream player, Illusion preamp and iBias amplifiers. Digital support has been included with USB, HDMI, coaxial, and optical inputs as well as Ethernet audio and Bluetooth streaming. ...[more]
