PBN's Olympian PX Fully Balanced Phono Preamp features a hefty outboard power supply and is fully balanced. It features XLR inputs and outputs and is best used with a balanced preamplifier. Designed by Erno Borbely and Peter Noerbaek, the Olympian PX is built in America and retails for $12,000. PBN manufactures another, even more expensive phono preamp. The bottom of the line $1749 B2B-1 is a superb performer that measures as well as it sounds so we look forward to auditioning the more expensive models!
