Yes, but we don’t recommend it. The SM-2A3 has been “voiced” in concert with micro power tube amps. Its frequency response curve is an acoustical inverse of traditional micro power SETs. When powered by such an amplifier, the result is a composite flat frequency response. However, amplifiers with linear frequency response [all solid state and most high-power tube] will improperly interface with the SM-2A3 response to create a bright, forward treble and an elevated midbass. Also, as a series-type crossover, the SM-2A3 tweeter doesn’t benefit from the overdrive protection of the other Soliloquy models and is thus most suitable for micro- and low-power tube amplification.
