Review: icOn4 AVC (Autoformer) Passive Preamplifier

Andrew Harrison recently reviewed two passive preamplifier/control units, namely the earlier series Life-Changer Audio icOn2 earlier this year (HIFICRITIC Vol 13 No1) and also the Bespoke Audio Company Pre-amplifier in (Vol 13 No2). Now a new and even more interesting version of the icOn series from that irrepressible designer and manufacturer Pál Nagy. He is full of enthusiasm for his subject and a burst of imagination allied to the versatility of the Arduino micro-computer module he incorporates, has allowed him to take the project further.
