   I think he means that better audio results can be achieved by providing true   
   dual-voltage supplies and eliminating all coupling caps.   
      
   The "DC amplifier" is a fine design, but will result in inferior audio   
   performance due to the caps.   
      
   Now, if someone would volunteer such a negative voltage generator circuit...

   Thanks.
