"Now I will concede one thing. I have used these current dumpers most of my life now. So my speakers were designed and voiced using those amps. So it is certainly possible my designs are optimal with those amps." He probably voiced the amps as well to obtain what he wanted . BTW ......I think it is a bit unfair and irresponsible to call Nelson Pass a plagiarist , especially without proof . He has many patents and gives his schematics , time and experience to the DIY community . Not only that , to most audiophiles , his work is the pinnacle of solid state design , build and sound quality .
