Parasound JC1+ Monoblock Power Amplifier
Reference-grade monoblock amplifier delivering immense power, precision, and musical detail for the ultimate high-end listening experience.
The Parasound JC1+ Monoblock Power Amplifier is the flagship creation of legendary designer John Curl, engineered to provide 450 watts into 8 ohms, 850 watts into 4 ohms, and up to 1,300 watts into 2 ohms. Its first 25 watts operate in pure Class A mode for ultra-smooth, detailed sound, while its transition to Class AB ensures full control and dynamic range at higher levels.
Designed with a massive 2.1 kVA R-core transformer and 198,000 µF of filter capacitance, the Parasound JC1+ delivers effortless power and stability even with difficult speaker loads. Its dual-mono architecture, ultra-wide bandwidth, and exceptionally low distortion deliver a level of control and realism that places it among the world’s finest amplifiers.
The Parasound JC1+ features both balanced XLR and unbalanced RCA inputs, gain selection (23 dB or 29 dB), and heavy-duty speaker terminals for precision connection. Whether used as a single-channel reference amp or paired for stereo operation, it offers commanding authority with delicacy and refinement.
