Jb0194, I'm using the circuit in the Sonus DAC's active output to do double duty as a DAC output and a line stage. Two pairs of resistors do the I/V conversion and a pair of relays connects to the passive attenuator and the grids of the 6N6P gain stage. With analog inputs, the relays connect a Lundalh line input trannie. If you are interested, pictures are posted on Dave Davenport's "Gallery". www.raleighaudio.com/tracy.htm BTW, this new twist that I mentioned will apply to your DAC. As to "different" rather that "better", Kevin has always in talking to me made the distinction between different and better. Whenever he has told me that a change was merely different, that's what it was. When he made the claim that a change was better, to my ears it has been so.
