Know before you buy
The Direct connection mode is designed specifically for use with Constellation preamplifiers. It bypasses certain input stages to minimize signal path interference, effectively reducing noise and distortion for a cleaner, more transparent sound.
No, this amplifier is not bridgeable. It is designed as a dedicated two-channel stereo amplifier and does not support mono-bridging configurations.
The Inspiration Stereo 1.0 delivers 200 watts per channel into 8-ohm speakers and doubles that to 400 watts per channel when driving 4-ohm loads, providing plenty of headroom for most high-end speaker systems.
While it is not rack-mountable, you should ensure your furniture can support its weight. The unit weighs 80 pounds and measures 17 inches wide by 19 inches deep, so it requires a sturdy, well-ventilated surface.
The amplifier offers versatile connectivity, including standard balanced XLR inputs and unbalanced RCA inputs. It also features a dedicated Direct XLR input for use with compatible Constellation preamplifiers.
The robust aluminum chassis provides a rigid, resonance-resistant foundation that protects the internal components. The distinctive honeycomb-vented side panels are engineered to manage heat dissipation efficiently, ensuring the amplifier remains stable during demanding playback.
