Topping Pre90 Preamplifier and Ext90 Input Extender

Topping’s Pre90 Preamplifier provides excellent clarity and control for your audio setup, and when paired with the Ext90 Input Extender delivers a full featured input array that fits right on your desktop in a neat little stack. The Pre90 uses Topping’s celebrated Nested Feedback Composite Amplifier (NFCA) technology to deliver excellent dynamic control to your amplification—with +16 decibels of maximum gain and an impressively expansive 145 decibels of dynamic range. Add that to a near-perfect 0.00007-percent total harmonic distortion, and you’ve got clean audio adequately delivered to whatever amp your setup is rocking. Plus, thanks to the safe volume function and gain memory per input, the performance won’t bring you any unwanted surprises in the loudness department. When you fold in the Ext90 Extender, you can add six powerful input ports (two RCA and four XLR) to carry that impressive functionality to even the most diversely routed systems.
