About the SIA-025
The SIA-025 is a Signature Series fully balanced solid-state integrated amplifier with five analogue inputs—three balanced XLR and two unbalanced RCA—and an XLR preamplifier output. It offers switchable Class A and Class AB operation, balanced speaker outputs, and a bypass function for use with an external surround processor. The original SIA-025 is distinct from the later SIA-025 Mk.II; the manufacturer’s current product listing is for the Mk.II, so its specifications and current pricing should not be assumed to apply exactly to the original model.
