Expansion Boards & Modules

An expansion board or module installs inside an amplifier, preamplifier, or CD player to add something it did not ship with: a DAC, a phono stage, streaming, or more inputs. The trade-off is fit: each one is built for named host models, so check it against the component you own. This collection gathers expansion boards and modules from Audia Flight, Kora, Primare, and Unison Research.

The Audia Flight FLS 1, FLS 9, and FLS 10 have two rear bays: the FLS DAC Board or XLR board in one, the MM/MC Phono Board or RCA board in the other. The Flight DAC Board and Phono Board are made for the Flight Three S, and the Digital Input Board for the Flight CD Three S. Kora's DAC Module and Phono Module fit the PR140. Primare's DM36 fits the I25, I35, and PRE35, the SM35 adds Prisma streaming once a DM35 or DM36 is in place, and the MM15 adds a moving magnet phono input to the I15. Unison Research's Phono Stage Board adds a phono input to the Unico Primo and Nuovo. For standalone boxes, see our DACs and phono preamps.
