The Reference 80S stereo amplifier continues Audio Research’s latest design effort in creating a vacuum-tube amplifier that not only redefines ultimate music reproduction, but does it in an incredibly beautiful package.  Outwardly, the 80S shares the same dimensions as the 160M. A single shallow whisper fan is built into the bottom plate. Flexibility is built-in, too, with XLR an...[more]

Circuitry Highlights Patent pending Krell iBias Class A technology allows our latest amplifiers to run in full Class A mode to full power while minimizing heat generation. All signal gain is realized in the current domain using discrete, proprietary, multiple-output current mirrors with extraordinary open loop linearity. There are no generic integrated circuits or op amps used anywhere. Current...[more]

The Inspiration 2 Stereo and Mono use the same Line Stage Gain Module input stage found in our top amplifiers. Hand-matched, low-noise transistors combine with a servo circuit that corrects any signal balance inconsistencies. The Inspiration 2 amplifiers’ Constellation Link interface connects to Constellation amplifiers to remove one amplification stage from the signal path, resulting in ...[more]

Every major section of the amplifier - power supply, input, driver, and output stages - have all been enhanced in this advancement. A new transformer winding pattern provides over 50% more current output from the same transformer footprint. This additional current offers greater headroom during dynamic passages. A reinvisioned input stage combines a brand new circuit topology with advanced comp...[more]

DarTzeel true passion for music reproduction, which they have nurtured for 25 years, led us on a long quest to design an audio amplifier that can convey the emotions at the heart of a musical performance.Absolute sounds are proud to introduce the long-awaited result, the darTZeel NHB-108 model one stereo amplifier.Most consumer products today—even some very expensive audio components—are designed ...[more]

Abundant power is required for realistic sound quality and is a cornerstone of Dan D’Agostino Master Audio Systems’ amplifier design. The Progression Stereo continues this practice. A graceful anodized Aluminum chassis houses a 2,000 VA power supply transformer coupled to nearly 100,000 microfarads of power supply storage capacitance. Paired to this foundation is a fully complementa...[more]

The Revelation 2 Stereo and Mono use the same Line Stage Gain Module input stage found in our top amplifiers. Hand-matched, low-noise transistors combine with a servo circuit that corrects for any inconsistencies in the signal balance. The Revelation 2 amplifiers’ Constellation Link interface connects to Constellation amplifiers to take one amplification stage out of the signal path-...[more]

The Statement Stereo represents a breathtaking evolution, joining extraordinary modern engineering with the legendary musicality of traditionally designed amplifiers. Thanks to our new Constellation Switched-Mode Power Supply (C-SMPS) with Power Factor Correction (PFC), the Statement Stereo delivers every bit of performance our engineers designed into it, regardless of the speaker or your count...[more]
