The Stageline is a separate phono stage, available in either moving coil or moving magnet versions, designed to optimise sound quality from a wide range of cartridges.

The Stageline can be powered either from a special socket on the rear of the NAIT 5 or by a separate supply such as the Flat-Cap 2 for even better performance. The Naim i-SUPPLY can also be used to deliver very cost effective 24V power to the Stageline.
