Audio research foundation series

Audio Research has introduced the Foundation Series utilising the same engineering and design team responsible for the Reference Series. The first three components include the LS28 line stage preamplifier, the PH9 phono stage and the DAC9 digital- to-analog converter. A new amplifier will follow, with other products to complete the series. All models will be available in both black and natural anodised aluminium finishes. Each unit comes with its own custom metal remote control.

Many of the parts in an Audio Research product are proprietary, while some are designed for a singular model.

The LS28 line stage features four balanced and four single-ended inputs and two sets of both balanced and single-ended outputs. The menu allows control of numerous parameters, including input naming, valve hours, auto shutdown, and home theatre passthrough. Phase invert and mono are also standard functions. At the heart of the LS28 are four 6H30 vacuum tubes in the analogue circuit. Shipping to begin this month.

The PH9 phono preamplifier includes a trio of 6H30 valves. Five different impedance settings allow for cartridge loading, which can be changed on the fly with the included metal remote. Cartridge impedance, valve hours, auto shutdown and other features are included in the menu system. Shipping to begin in July.

The DAC9 digital-to-analog converter decodes most current formats with valve technology. Five digital connections – USB, RCA, BNC, AES/EBU and Toslink – provide connectivity. Quad DAC architecture and decoding resolutions from red book CD up to 384 kHz and native DSD sampling rates are included. 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 customisation of the digital signal. Shipping to begin in August.

The units described above are priced at £6,998 each.
