Parasound JC2 BP is the best high-end stereo preamplifier that the famous American company Parasound has ever created. The Parasound JC2 BP stereo preamplifier is designed using a “dual mono” design using massive centimeter-thick screens, which, along with innovative design solutions, made it possible to achieve an incredibly high signal-to-noise ratio of 116 dB. Refusal to use a standard toroidal network transformer in favor of a new design transformer with an R-type core eliminates its own radiation of interference due to complex balanced-type windings.

The design uses separate power supplies for audio circuits and relay windings, for example, even control triggers and mode indication LEDs are powered separately! Just like the famous JC1 power amplifier, the new super-preamplifier uses the famous DC-servo circuit, which eliminates capacitors from the audio path that negatively affect the sound. In the new combination of the JC2 BP preamplifier with the JC1 monoblock, there are no capacitors along the entire sound path, and the frequency range is forcibly limited from below at a frequency of 5 Hz. The result is simply stunning – at home you can now really feel even the size of the concert hall where the recording was made and hear the simultaneous gasps of thousands of people when something amazing happens on stage.

The JC2 BP volume control is completely analog, motorized, no digital circuits or processors that can affect the sound. The traditional balance control is simply excluded from the circuit – it greatly increases the parasitic signal penetration between stereo channels, which affects the virtual sound stage. Instead, gain calibration is used for each channel using individual TKD regulators. Even the relays that switch the audio signal have silver conductor contacts coated with a layer of gold.

The Parasound JC2 BP (preamplifier) ​​and JC1 (monoblock) set is not picky about recording quality and from the first notes wins the listener over, captivating you not with contemplation of the sound ins and outs of a musical work, but with its content. Put on an album by Mark Knopfler, and you will inhale the “American” aroma – the sound is warm, soulful, but transparent and not lazy, with good drive. If you want to listen to classical music, for example, the symphonic poems of B. Smetana, Parasound will be light and lyrical; if you listen to the Rapture of Deep of the gray-haired rockers Deep Purple, you are guaranteed drive and pressure.

Parasound JC1/JC2 BP is an extremely attractive offer for those who are not used to throwing away money – neither big nor small, and expect to get the most out of their money even when purchasing High-End equipment. It’s also a great option if you want the composition of your music library to be dictated solely by your musical taste, and not by the quality of the recordings themselves.
