Parasound HALO JC3+ Phono Amplifier LNIB

Designed by John Curl, the JC3+ is Parasound's top of the line phono stage. It features a dual-mono, all-analog architecture for ultra-low noise and stunning musicality. With support for both MM and MC cartridges (adjustable loading), and balanced XLR plus gold-plated RCA outputs, the JC 3+ integrates seamlessly into high-end analog systems. Winner of many awards. Parasound is not currently available in Canada - the last retail price of the JC3+ was $4850. This is a one owner unit, bought from Upscale Audio. Only used a few months.

No sales tax. Shipping is no problem.
