The SCA2 is a highly acclaimed, hand-built ultra high-end preamplifier from legendary British ATC. It is renowned for its transparent and extremely noise-free circuit design.
It has previously been used in a music studio, and very limitedly there, as I have other preamps. It is equipped with a phono/RIAA stage, so turntables can be connected directly to the unit.
Below is some info from the manufacturer.
The SCA2 is ATC's highest performance preamplifier and has been in continuous production since 1996, testament to its exceptional performance and timeless styling. Balanced and unbalanced inputs and outputs provide flexible connectivity to a very wide range of partnering equipment. The phono stage is fully configurable for both gain, resistive and capacitive loading and its low-noise design makes it well suited to even the lowest output moving coil cartridges.
