Description
Reference 6SE line pre amp
Audio Research has produced some of the finest components for music reproduction; this is especially true with regard to preamplifiers. In 1973, the SP3 was hailed by every major critic as the best preamplifier available, and this tradition of excellence has continued ever since. The Reference Series from Audio Research was first introduced in 1995 and has been the ultimate representation of performance, musicality and dynamics. The Reference 6SE is the latest chapter in our story.
With a single gain stage, the 6SE is a fully-balanced, Class-A design with zero feedback. In addition to six long-life 6H30 tubes in the gain stage, the enormous and highly-regulated power supply has another 6H30 with a 6550 providing vacuum-tube regulation.
The Reference 6SE replaces the Reference 6 and offers the highest performance ever available in a single-chassis preamplifier. Benefitting from the development that went into the Reference 160-series amplifiers, and the latest Reference 750SEL, the 6SE incorporates a myriad of new parts that have been judiciously incorporated into its design. The final 6SE would not have been possible without these revolutionary amplifiers.
Regardless of the recording, the improvement in sound is immediate and compelling. Effortless, dynamic, and dimensional. The speed and resolution merge with musical color and textures that are both accurate and captivating.
Reference 250 mono power amplifier
The concept of a large monoblock amplifier is to provide control to a speaker. The difficult part of the job is maintaining finesse and musicality while doing it. Audio Research has produced some of the most critically acclaimed products during its 42-year history and the new Reference 250 aims to break new ground.
From the moment the music begins, the foundation of an exceptional musical experience is evident. Sound emerges from an inky black background, revealing microdetails and performance cues typically reserved for the live performance. Substantial, fundamental bass underscores the event with resolution and textural accuracy. Space around performers and groups of instruments stretch before you onto a lifelike stage with scale and body. Dynamics swing from silent passages to grand fortissimos without effort or strain. This is high definition listening.
The Reference 250 features new enhancements outside as well as major performance advances inside. First, you will notice a more modern, monochromatic appearance, including a new front panel with a small aluminum power button. An analog meter with adjustable illumination is set in the front panel is capable of displaying power output and tube bias settings. A new low turbulence fan provide effective yet silent cooling. Internally, the Reference 250 is outfitted with the KT120 output tubes and a bulk power supply 50 percent larger than its predecessor. Connections include accommodation for 4, 8 or 16 ohm speakers, an XLR input as well as 12 volt trigger connections.
