DESCRIPTION
Uniting source components with power amplifiers, it must perform the critical functions of impedance matching, level balancing and volume control while maintaining perfect signal accuracy and channel integrity. Adding nothing. Taking nothing away.
While the perfect preamplifier continues to be a technical challenge for audio designers, we believe the 525 gets closest to the ideal.
