   **Indeed. However, several points:   
      
   * The most critical aspects to good sound reproduction lie with the DAC   
   and the output stages. The best DACs are generally regarded to be R2R   
   types. These types of DACs tend to be much larger than the more popular   
   Sigma/Delta types.   
   * RAM based players are not immune from failure of the RAM itself. The   
   type of RAM used has a finite life-span.
