That's Seduction, a phono preamp. It was introduced in 2002, and upgraded in 2003 with the PT-1 and the C4S - the narrow PC board. The signal-carrying caps appear to have been upgraded by the builder.
It was discontinued in 2007, around the time Eros was introduced, but resurrected in 2014 under the name Reduction, revised as version 1.1 in 2020, and discontinued it 2023.
