For upgrading Quad ESL57 (and 63 as well) or your own precious fullrange ESL projects

A.) That one really does not give any chance to leakage. And therefore will improve transient response by at least one power. Also efficiency of the transducer is ameliorated.

B.)The Quad57 HV wires are corroded after at least 10 years. They even resist correct resoldering, or the strands are going to break,  and consequently the cable becomes too short for the soldering points. So completely renewing the cables of th Quad ESL57 is nearly a must.
