Chord Electronics Ultima Pre 3 Preamplifier Review


The ULTIMA PRE 3 is an all-new ground-up-design preamplifier containing the very latest proprietary power supply technology and the latest circuit design.


Built from the ground up, the UTLIMA PRE 3 takes advantage of the very latest developments in advanced low-distortion power supplies. These advanced devices offer exceptionally low noise and outstanding amplifier operation. Coupled with our latest design developments, the PRE 3 offers new levels of preamplifier performance.


The UTLIMA PRE 3 is equipped with five analog inputs (two balanced and three unbalanced) all of which benefit from individual buffering and are selectively filtered against potential ingress from radio frequency interference.


Externally, the PRE 3 benefits from a completely redesigned aesthetic with a central circular power sphere flanked by a new volume control and balance/AV bypass selector, both of which benefit from a new ergonomic knob design.

Additional features include an AV bypass, plus a 5 V charging USB Type-A port.
