The AD-2850 uses printed circuit boards made from glass cloth fluorocarbon resin, housed in a sturdy aluminium enclosure to minimise any kind of external influence. The input terminals are connected to the amplification circuitry by the shortest possible route, realising outstanding signal/noise ratio. The use of a DIN standard connector for the link to the host component provides enhanced reliability.

Who is this for?

The Accuphase AD-2900 is designed for vinyl enthusiasts who want high-end analogue playback integrated directly into their compatible Accuphase preamplifier or integrated amplifier. It suits listeners seeking the performance of a premium standalone phono stage while maintaining the elegance and simplicity of an all-Accuphase system.

Supporting both moving magnet and moving coil cartridges, the AD-2900 is ideal for high-quality turntable setups where low noise, transparency, and tonal realism are priorities. It pairs particularly well with resolving systems that can reveal the improved dynamics, detail, and musical flow that a refined phono stage brings to vinyl playback.

For customers wanting a seamless and highly capable analogue solution without adding extra boxes or cabling, the AD-2900 is an elegant upgrade that fits naturally within a serious Accuphase system.
