About the Parasound Halo JC 2 BP
Wide open soundstage
Wide open soundstage
Parasound's JC 2 BP is like a perfect canvas which lets you fully experience the color and texture of your music. This all-analog stereo preamp identical in circuitry to its predecessor — the longtime audiophile favorite JC 2 — except for the addition of a home theater bypass function. Part of its beauty is that it doesn't try to do too much. There's no DAC, no Bluetooth®, not even a phono input. Rather, the JC 2 BP is designed to give you the best possible sound with your streaming components, outboard phono preamps, and other sources.
Silence is golden, by design

Beautiful topology: a 3/8" aluminum partition isolates the power supply from the right and left channel circuitry, and each channel is on its own separate circuit board.
Every design detail in the JC 2 BP serves to minimize interaction between its component parts. For instance, 3/8"-thick aluminum partitioning isolates the high-current, low-impedance power supply. On the other side of the partition, separate circuit boards for the left and right channels keep interference at bay.
Parasound has also minimized long wire runs by placing master and individual channel switches and level controls as close as possible to the actual input circuitry. Non-audio control circuitry, like LED lights on the display, run on a separate power supply.
All this adds up to almost nothing — an utterly silent background. The low noise floor allows the JC 2 BP to deliver warm and articulate musical nuance.
The legacy of John Curl
The JC 2 BP features circuitry designed by by John Curl, a legend in audio engineering. He started his career in the 1970s, designing tape and video recorders at Ampex, and he had a hand in building the Grateful Dead's Wall of Sound. Curl has worked with Parasound since 1989, designing all of their high-power amplifiers and more. The power supply, transistors, capacitors and other parts in the JC 2 BP were chosen to offer high performance at a reasonable price.
