Cambridge Audio 851 Pre-Amplifier
The pre-amp stage is all about minimal colouration. Take the source signal and pass it onto the power amp stage with as little interference as possible. That’s exactly what the 851E does, and coupled with its solid-state volume control, it retains audio signal purity and precision even at the lowest listening levels.
The toroidal transformer helps, as does our insistence on using only audiophile-grade components; many hours of fine tuning also play their part. The 851E has a broad range of connection options, including three switchable between unbalanced RCA and balanced XLR, the later ideal for high-end sources. Traditional sources get six RCA unbalanced inputs, plus there’s a dedicated sub woofer output and two sets of speaker terminals.
