Peter, I am very convinced that the additional background noise with injection of AD/DA stage comes from the fact that your AD/DA stage out more gain then you Sansui direct. Use the Sansui’s internal generator to make sure that when you compare the AD/DA with “Sansui Direct” then your signals are at the same levels. You might use AC voltmeter on amp’s outputs with Sansui’s generator engaged. Use analog voltage dividers to synchronize the gains on both chains. Rerurn to Romy the Cat's Site
