Audio Research REF 6SE
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.

Audio Research REF 80S
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.
The 80S was created for the music lover who does not require the output power of its larger siblings, the Reference 160S stereo and 160M mono amplifiers. The 80S continues the design ethos, including dual GhostMeters® that float in front of four KT150 output tubes. Extruded panels, a vital part of the all-aluminum chassis, provide rigidity and beauty.

POWER OUTPUT
70 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 140 watts (33 watts in Triode mode) per channel, below 0.04% at 1 watt (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not critical)
POWER BANDWIDTH
(-3dB points) 7Hz to 68kHz
FREQUENCY RESPONSE
(-3dB points at 1 watt) 0.7Hz to 94kHz
INPUT SENSITIVITY
1.4V RMS Balanced for rated output. (25.5 dB gain into 8 ohms);
0.7V RMS SE for rated output.

INPUT IMPEDANCE
300K ohms Balanced, 75K ohms Single Ended
Audio Research I/50
The I/50 Integrated Amplifier is the first product in an all-new series from Audio Research. Functionally simple, visually engaging, and musically sublime – the I/50 takes music listening to a whole new experience.
Hand-crafted in Minnesota, the I/50 is built with the same attention to detail as all other Audio Research products – each one even gets its own listening test with sonic designer, Warren Gehl.

Audio Research DAC 9 Tube DAC
The DAC9 digital-to-analog converter decodes most current formats with state-of-the-art vacuum tube technology. Five digital connections – USB, RCA, BNC, AES/EBU, and Toslink – provide connectivity to all of your digital sources. Quad DAC architecture provides a balanced digital signal, wide dynamic range, and decoding resolutions from red book CD up to 384 kHz and native DSD sampling rates. A pair of 6H30 vacuum tubes are the heart of the analog circuit. Both balanced and single-ended connectors are provided for output connectivity. Native-rate upsampling and selectable digital filters allow customization of the digital signal.
Audio Research is pleased to introduce the Foundation Series. From the same engineering and design team responsible for the award-winning Reference Series, the Foundation family of vacuum tube components has been created to provide incredible musical experiences. Spatial definition, dynamics and detail abound while providing the most natural musical experience.
